The platform manages geo-spatial information and provides analytics services and tools for critical assets and infrastructures monitoring, for customers and prospects worldwide.  The huge amount of geo-spatial data to be managed required us to rely on a cloud-based distributed architecture, based on open-source big-data management solutions. In particular, we defined a Docker container-based distributed infrastructure, using Geomesa and Accumulo. The talk will delve into details of architecture and strategies used to ingest, store, indexing, and analyzing the geo-referenced data, for optimal performance in terms of concurrent content delivery to multiple web clients world-wide, each acting on a set of Areas of Interest. Case studies will be presented to show the value of the proposed solution, in terms of user experience and real-time processing capability.\n\nNone","original_language":"eng","persons":["Marcello"],"tags":["bucharest","219","2019","General"],"view_count":330,"promoted":false,"date":"2019-08-30T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2025-03-17T00:45:05.061+01:00","length":1192,"duration":1192,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/219-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/219-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/219-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/219-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-219-a-geo-spatial-big-data-infrastructure-for-asset-management","url":"https://api.media.ccc.de/public/events/d3a697b4-8bc4-57ba-934c-2747fbec39ab","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7465,"event_guid":"d2b2bdd0-36fa-5ae1-aba0-a38960010e3b","weight":4},{"event_id":7468,"event_guid":"43d9cc0e-3fb9-55b2-a3a1-b9cfbe928e23","weight":2},{"event_id":7469,"event_guid":"c0174aef-c7a6-5d21-8dfe-e592c5a4eff3","weight":3},{"event_id":7477,"event_guid":"9227fcf3-b7b2-5a7a-b135-3e7a18341a82","weight":4},{"event_id":7483,"event_guid":"54f0806e-4257-53c6-a558-e336ee584bb5","weight":1},{"event_id":7484,"event_guid":"b4d6c8c6-688b-5273-aa8f-a2044128ac13","weight":2},{"event_id":7487,"event_guid":"6f1b8b15-b44a-592c-b3e9-96bd9e0fbce3","weight":5},{"event_id":7488,"event_guid":"0a3e23aa-d593-58cd-a3a1-7991e3a3a064","weight":1},{"event_id":7492,"event_guid":"f65e1c2f-8bde-5c89-a128-e113b0b9a3f6","weight":4},{"event_id":7501,"event_guid":"a4aa4222-f2ca-5e0c-94f6-4c7a3595d1a2","weight":4},{"event_id":7514,"event_guid":"0d63b0b4-259d-5114-8c8f-18604b514f7d","weight":5},{"event_id":7518,"event_guid":"8773035b-d16c-5cf3-902d-43abc7e5dab7","weight":4},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":6},{"event_id":7527,"event_guid":"b05efa77-03a4-5ff9-a037-06d5aa2a1b6d","weight":2},{"event_id":7536,"event_guid":"9f921eab-53c5-5ce7-9489-45a586162248","weight":1},{"event_id":7562,"event_guid":"79cf5a8f-8601-533e-82c5-56626447534c","weight":2},{"event_id":7579,"event_guid":"0112454d-62b2-5132-8971-73c7fdb972d0","weight":5},{"event_id":7590,"event_guid":"0bdb57e7-edb8-50e8-a60e-4ec5480e14b9","weight":4},{"event_id":7607,"event_guid":"d0794cae-d707-584c-8879-6c438a603486","weight":3},{"event_id":7616,"event_guid":"23bc1246-3fcb-5ce4-ac80-f8c176a25d97","weight":1},{"event_id":7619,"event_guid":"21ffa487-5dfd-57d3-acce-8fd048ead7cf","weight":4},{"event_id":7623,"event_guid":"d7305220-5dac-5581-bf1b-14e735c39756","weight":2},{"event_id":7624,"event_guid":"69079f64-448d-55b5-9cb3-7089547c370d","weight":2},{"event_id":7626,"event_guid":"227ae37a-41aa-53d7-944a-2e9b7c8d99a7","weight":3},{"event_id":7641,"event_guid":"d5b00dcc-d898-5a3a-bc8f-8e62d492bf4e","weight":1},{"event_id":7652,"event_guid":"e04c27d0-8ff8-5bf4-b932-34db4e4fdf5b","weight":4},{"event_id":7655,"event_guid":"3b5c1185-42c2-5e87-b4ba-779be1a3297b","weight":1},{"event_id":7657,"event_guid":"13347d51-f447-50a0-86b3-1e0833dedc68","weight":1},{"event_id":7662,"event_guid":"a8fbf537-cbe1-5f17-aa73-97d64132f660","weight":4},{"event_id":7663,"event_guid":"1b265f5f-a622-52e0-a2a4-88105aa09aba","weight":7},{"event_id":7664,"event_guid":"bc480eaa-8db8-54d0-bc53-32a81725f2d9","weight":2},{"event_id":7674,"event_guid":"ac484924-85f6-5195-bf5b-9f689f24ef57","weight":2},{"event_id":7695,"event_guid":"5df0ebe1-cfe2-54c4-a0c8-40e35a6de826","weight":4},{"event_id":7733,"event_guid":"0ba5c644-2353-5225-972e-6e3958f74f3e","weight":2},{"event_id":7749,"event_guid":"5117b85e-052d-5b96-bcc3-f14e953b887a","weight":4},{"event_id":7756,"event_guid":"c4299de5-e39e-576d-93bb-7ae47fee42af","weight":4},{"event_id":7757,"event_guid":"08e7e90e-7da4-524d-8875-b38d23b6c1cf","weight":2}]},{"guid":"88c4c363-fafc-52a3-9ddf-60753caed575","title":"inous Initiative - An eco-system for OGC IndoorGML","subtitle":null,"slug":"bucharest-311-inous-initiative-an-eco-system-for-ogc-indoorgml","link":"https://talks.2019.foss4g.org/bucharest/talk/ZMTKLV/","description":"Due to the growing population in urban areas, the building structures become more huge and complicated. The demands for geospatial information and services in indoor space are increasing as well as outdoor spaces. An OGC standard, called IndoorGML, was published to provide a standard indoor spatial model and exchange data format. And inous R\u0026D initiative has been established to set up an eco-system for IndoorGML based on open source software. In this talk, we will present an overview of this initiative and details of the achievements so far. First, it will covers several approached for 3D indoor map construction in IndoorGML from point cloud, blueprint maps, as well as crowdsource. Second, the conversion issues from CAD and BIM data to IndoorGML will be also discussed in the talk. Third, we will present several interesting application services of the initiative such as sharing IndoorGML data via 3D geo-portal and voice map service for blind people.\n\nNone","original_language":"eng","persons":["Do-Hun Kang","Byeong-Gon Kim","Yongsu Song","Ki-Joune

sheer amount of statistics collected as the world entered the age of Big Data transformed computers from simple tools for processing data into complex machines able to present the results of this processing as compelling visuals with little to no human input. And when it comes to presenting the evolution of phenomena that vary in space and time, there is no better solution than a map.\nAs part of a project involving a major institutional client, we developed a FOSSGIS-based custom spatial visualisation widget for use with Microsoft’s PowerBi. Integrating with an environment that includes a plethora of graphical representations for data, the developed widget, built on top of OpenLayers, provides a novel view of data with spatial characteristics. Unlike the default map widgets, it allows the use of custom, time-enabled geometries, as well as custom basemaps, consumed using open standards (GeoJSON, WMS), custom projections (with Proj4js), feature zoom across the International Date Line and complex visualisation using charts on top of choropleth maps. We thus show the advantages of using open-source GIS technology on top of proprietary frameworks, providing advanced, project-specific features supported by a wide community.\n\nNone","original_language":"eng","persons":["Daniel Urda","Florin Iosub"],"tags":["bucharest","247","2019","General"],"view_count":200,"promoted":false,"date":"2019-08-30T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2025-06-30T16:30:04.409+02:00","length":1379,"duration":1379,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/247-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/247-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/247-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/247-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-247-big-data-above-and-beyond-openlayers-and-power-bi-working-together","url":"https://api.media.ccc.de/public/events/a38570ce-3943-5e91-aa70-1333d5d9cc48","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":4326,"event_guid":"1b4ced58-cf46-4f36-9ddc-bcb567fa9f47","weight":1},{"event_id":7473,"event_guid":"feda735f-5467-56f0-9ddf-55cefdf60199","weight":1},{"event_id":7477,"event_guid":"9227fcf3-b7b2-5a7a-b135-3e7a18341a82","weight":2},{"event_id":7480,"event_guid":"603a5649-724a-53d7-ac20-ff7d520696d3","weight":2},{"event_id":7487,"event_guid":"6f1b8b15-b44a-592c-b3e9-96bd9e0fbce3","weight":3},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":2},{"event_id":7524,"event_guid":"f58c39cb-2250-51b5-8902-d52f713c934b","weight":2},{"event_id":7525,"event_guid":"9cb9910c-3b3f-5cec-830b-24e93de3edc9","weight":2},{"event_id":7546,"event_guid":"c2504e4b-02f0-5347-92b9-bcd1d86d7df4","weight":1},{"event_id":7552,"event_guid":"4c2f4b81-1316-502d-870c-dc39567b782e","weight":1},{"event_id":7560,"event_guid":"fb1d6f2b-e06d-5bfb-9ecb-0768ed3a2fb0","weight":2},{"event_id":7587,"event_guid":"1dac21fe-e493-541b-8e5f-ba1c1f15db2c","weight":1},{"event_id":7590,"event_guid":"0bdb57e7-edb8-50e8-a60e-4ec5480e14b9","weight":2},{"event_id":7594,"event_guid":"9f3b41cc-dc93-55d8-a318-7b7740109b71","weight":2},{"event_id":7595,"event_guid":"1b45aaaa-70dc-5f27-8b7b-64dc0fe409a5","weight":4},{"event_id":7607,"event_guid":"d0794cae-d707-584c-8879-6c438a603486","weight":2},{"event_id":7621,"event_guid":"8e5e286c-0e3c-5c18-9122-dee8e92752cc","weight":1},{"event_id":7635,"event_guid":"a134c0ce-1291-54b1-a56e-547284a962f0","weight":1},{"event_id":7651,"event_guid":"84c94e48-3002-55f3-9d4a-c66f5d2e4198","weight":2},{"event_id":7663,"event_guid":"1b265f5f-a622-52e0-a2a4-88105aa09aba","weight":2},{"event_id":7667,"event_guid":"4bc8bbe5-cb04-5a2b-b441-a696be055948","weight":2},{"event_id":7670,"event_guid":"87692512-45dd-5b7b-9456-62d1a04a185e","weight":2},{"event_id":7672,"event_guid":"1c58bd3e-15f6-51a3-af44-9d6a75f31556","weight":2},{"event_id":7691,"event_guid":"51a27fc2-ea89-5b31-8a60-fed8cdc9ef91","weight":2},{"event_id":7692,"event_guid":"3c0ea464-ce0e-5676-a977-075148d7bbdd","weight":2},{"event_id":7698,"event_guid":"61a1baea-9b7c-5f64-bef2-094b291f77fd","weight":2},{"event_id":7701,"event_guid":"d3a697b4-8bc4-57ba-934c-2747fbec39ab","weight":1},{"event_id":7707,"event_guid":"8f9b67d8-fd60-522f-9a5b-6f0f81626e5c","weight":1},{"event_id":7721,"event_guid":"9462ccbb-1601-5d12-8756-5e11e3134112","weight":1},{"event_id":7738,"event_guid":"ecbd87e4-3c54-5fbe-b5fd-aefc02e7c95d","weight":1},{"event_id":7743,"event_guid":"c393e563-c11d-5111-aa92-fc579ac7ecc9","weight":1},{"event_id":7749,"event_guid":"5117b85e-052d-5b96-bcc3-f14e953b887a","weight":2},{"event_id":7750,"event_guid":"123bf2f0-6f17-5563-96c7-430cfe28dd0d","weight":1}]},{"guid":"ecbd87e4-3c54-5fbe-b5fd-aefc02e7c95d","title":"An open drought monitoring system for the Deduru Oya basin in Sri Lanka in the context of the 4onse project.","subtitle":null,"slug":"bucharest-72-an-open-drought-monitoring-system-for-the-deduru-oya-basin-in-sri-lanka-in-the-context-of-the-4onse-project-","link":"https://talks.2019.foss4g.org/bucharest/talk/MLUXMW/","description":"During the last decades, many climatic parameters are more and more deviating from the average according to the mean values registered since consistent weather observations are available. The World Meteorological Organization (WMO) stated that the 2015, 2016 and 2017 years were the warmest since 1850 [1]. This trend is going to be confirmed in 2018 according to the preliminary data analysis of the last year. Drought events will likely occur more frequently or with an higher intensity either in Europe and in Asia [2,3].  Sri Lanka is not an exception, the norther-east area is already facing long period with very few precipitation events. Drought has multiple impacts on environmental and socio-economic aspects such as water resources management, human lives, energy consumption and many others. This climatic scenario highlights the importance of the development of monitoring systems to support the management of the drought risk. \nThe 4onse project (analysis of Open, Non-conventional, Sustainable and Effective monitoring systems), funded by the Swiss National Science Foundation (SNSF), aims to evaluate “non-conventional” Environmental Monitoring System (EMS) based on open technologies both hardware and software. At this state of the project, after developing and validating the prototype [4], 30 weather stations have been deployed in the Deduru Oya Sri Lankan basin and collecting the basic weather parameters (air temperature, humidity, pressure, accumulated rain, wind speed and wind direction). The system can help developing and low-income countries in coping the lack in the monitoring and management of natural hazards. In fact, thanks to the collected data, it is possible to elaborate some drought indexes which help in evaluating the intensity of the dry periods. The Standard Precipitation Index (SPI) has been selected as principal indicator to evaluate droughts. The SPI has been calculated integrating the data collected by the 4onse stations together with the Climate Hazards group Infrared Precipitation with Stations (CHIRPS) dataset. In this paper, the authors present the results of the methodology used and the proposed system to share the information that are useful to better take mitigation actions in time.\n\n[1] WMO WMO statement on the state of the global climate in 2017; 2018; ISBN 978-92-63-11212-5.\n[2] Spinoni, J.; Vogt, J.V.; Naumann, G.; Barbosa, P.; Dosio, A.

government has launched the 'Public Safety Map' to provide safety information, with a web map service since 2013. It collects 160 pieces of information from 29 agencies, and compiles Public Safety Information maps in eight categories. In 2018, we analyzed performance and usage patterns to evaluate the use of the system. This analysis revealed that users were having difficulty in accessing the thematic map rather than the information itself. Users unfamiliar with the service had to click on the menu tree structure in order to find the desired topic, which resulted in a decrease in service utilization. It also became clear that it was difficult for users to find their desired thematic map, because there were over 214 service menus. In order to enhance accessibility through an improved user interface, we applied a new technology: a chatbot. Now users can find the desired thematic map and move to the area of interest through dialogue with the chatbot.

Traditionally, each water organization was required to have the expensive infrastructure and capacity to access large global datasets and develop their own models to forecast streamflow useful for decision-makers. Using the GEOGLOWS global streamflow services they no longer have to have their own internal infrastructure for modeling, but instead can access the streamflow forecasts through web services and use them according to their own prioritized needs. This freely provided streamflow information, which leverages the hydrometeorological computational expertise of the GEOGLOWS Partnership, saves millions of dollars and allows national and local

Telekom AG (DTAG) revolutionises the planning process of fibre networks (FTTH) to\n * increase number of connected households and industries dramatically, and\n * shorten the time to market in general.\n\nFor this goal DTAG, advanced geoprocessing algorithms including artificial intelligence (AI) automate the conversion of surface information into cost optimised potential trenches used in the fibre build process. The surface information is gathered by terrestrial laser scanners and photos as well as extracted through a complex analysis from aerial orthophotos. This surface information then is used in conjunction with other (open) data as an input for the provisioning of potential trenches needed for FTTH. The processing of these orthophotos as well as the calculation of trenches are handled by the open source actinia cloud geoprocessing engine. Actinia is a new OSGeo community project, offering a REST API to GRASS GIS. The actinia processes are scaled and implemented as a service in the Open Telekom Cloud.\n\nIn this talk, we present the handling of large and complex input data in the FTTH-process. Focus is on the usage of actinia, and how actinia supports a core process of the largest German telecommunication provider.\n\nNone","original_language":"eng","persons":["Markus Neteler","Markus Metz","Anika Bettge","Torsten Drey","Carmen Tawalika"],"tags":["bucharest","234","2019","General"],"view_count":119,"promoted":false,"date":"2019-08-29T00:00:00.000+02:00","release_date":"2019-08-29T02:00:00.000+02:00","updated_at":"2024-12-22T13:45:02.767+01:00","length":1529,"duration":1529,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/234-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/234-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/234-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/234-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-234-how-digging-in-the-earth-for-the-fibre-roll-out-took-grass-to-the-cloud","url":"https://api.media.ccc.de/public/events/c2504e4b-02f0-5347-92b9-bcd1d86d7df4","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":2766,"event_guid":"3d7c49e7-7e31-11e5-b91e-b21625562c7b","weight":1},{"event_id":6850,"event_guid":"804c595e-98f9-5ab4-9bbc-c0d2b5582b1e","weight":2},{"event_id":7394,"event_guid":"14a2c922-697c-4073-885c-568850a390a7","weight":1},{"event_id":7409,"event_guid":"b4902bdb-38ab-5abb-9884-5efdb4bca02f","weight":1},{"event_id":7459,"event_guid":"4263620e-f36f-4408-b702-01481e0efbd7","weight":1},{"event_id":7464,"event_guid":"a5a5b7b3-060a-582a-b1b2-f626a681e79b","weight":3},{"event_id":7478,"event_guid":"ae1cdec5-93fe-5638-a167-faa6e81cf9c6","weight":1},{"event_id":7481,"event_guid":"c6a74a91-9d1a-55b9-ae43-118e9abb2617","weight":1},{"event_id":7487,"event_guid":"6f1b8b15-b44a-592c-b3e9-96bd9e0fbce3","weight":2},{"event_id":7495,"event_guid":"bffc8bd9-0df8-5543-8c24-254c05092bbd","weight":1},{"event_id":7497,"event_guid":"ee2c0473-7931-5239-85f0-0385fb68054e","weight":1},{"event_id":7501,"event_guid":"a4aa4222-f2ca-5e0c-94f6-4c7a3595d1a2","weight":1},{"event_id":7520,"event_guid":"2e1e926d-3eaa-5fa1-83b3-1a8e001df0c6","weight":1},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":2},{"event_id":7537,"event_guid":"14a1b81d-47c2-560c-9525-26e35f4caf54","weight":3},{"event_id":7542,"event_guid":"7e354528-0b5a-512d-be47-bdc7447bb93b","weight":2},{"event_id":7552,"event_guid":"4c2f4b81-1316-502d-870c-dc39567b782e","weight":1},{"event_id":7553,"event_guid":"9f0999f8-6941-5308-b1a8-f094c738245f","weight":1},{"event_id":7559,"event_guid":"69de3e04-de0f-5325-9862-023143b3252b","weight":2},{"event_id":7575,"event_guid":"bcca12c5-309f-588b-a67e-c5f1fc31f998","weight":1},{"event_id":7609,"event_guid":"64785b52-3c01-587f-ad49-224968c337df","weight":10},{"event_id":7630,"event_guid":"2922816b-f00a-5fc1-97e6-69df1a0c98ab","weight":1},{"event_id":7663,"event_guid":"1b265f5f-a622-52e0-a2a4-88105aa09aba","weight":1},{"event_id":7671,"event_guid":"a38570ce-3943-5e91-aa70-1333d5d9cc48","weight":1},{"event_id":7672,"event_guid":"1c58bd3e-15f6-51a3-af44-9d6a75f31556","weight":1},{"event_id":7701,"event_guid":"d3a697b4-8bc4-57ba-934c-2747fbec39ab","weight":2},{"event_id":7743,"event_guid":"c393e563-c11d-5111-aa92-fc579ac7ecc9","weight":2},{"event_id":7749,"event_guid":"5117b85e-052d-5b96-bcc3-f14e953b887a","weight":1},{"event_id":7761,"event_guid":"ebffdad1-55ef-4b66-b7cd-a170c801c147","weight":1}]},{"guid":"de42794d-e607-5d76-9b1e-3b5e52bd6c68","title":"Automated GIS-based Complex Developed for the Long-term monitoring of Growing Season Parameters Using Remote Sensing Data","subtitle":null,"slug":"bucharest-87-automated-gis-based-complex-developed-for-the-long-term-monitoring-of-growing-season-parameters-using-remote-sensing-data","link":"https://talks.2019.foss4g.org/bucharest/talk/77BJYC/","description":"A number of climate change research projects discover dependencies between dynamics of vegetation indexes and dynamics of meteorological parameters, which make possible estimation and monitoring of growing season parameters using remote sensing data. In our study, we use Normalized Difference Water Index (NDWI) that can be derived automatically from the daily satellite imagery collected by MODIS sensor. The NDWI indicates amount of liquid water in plant tissue, and then reflects change of vegetation growing conditions and particularly growing season change. \n\nTo ensure monitoring of growing season parameters we elaborated an automated software complex that incorporates desktop Geographic Information System (GIS) software (QGIS was used), geospatial database and complex of computational tools. The GIS is used as an infrastructure element for operating and visualization purposes, while the database together with computational tools enable storage and multipurpose processing of meteorological and remote sensing data. The meteorological data is collected for the past period of 130 years and NDWI data for the 20 years. Developed complex is tested on the example of Republic of Komi (Northern part of European Russia) that is covered by Taiga and Tundra natural zones and impacted by different climate forming factors. \n\nCurrently we describe architecture of the elaborated complex and design of data processing chains. Elaborated complex ensure automation of downloading raw remote sensing data and reprocessing it into gridded NDWI maps. In this context, it can be underlined that daily collected MODIS imagery can be discovered as big geospatial data, due to this we were needed to resolve a number of optimization tasks to implement its processing. Subsequently, NDWI data is used to produce gridded map series that reflects time and spatial dynamics of growing season characteristics. Produced data have a special significance for areas with sparse meteorological network.\n\nKeywords: GIS, Remote Sensing Data, Climate Change, Growing Season, Vegetation Indexes, MODIS, NDWI.\n\nNone","original_language":"eng","persons":["V.

We are clearly facing a rapid and global trend, that will affect daily life in the next few decades. It is, therefore, crucial to managing this social and cultural change in a much more sustainable way, compared to what was done in the past.\nWithin this framework, the collection, integration, and sharing of reliable and open spatial information is a key factor, benefiting both of different space (Earth Observation (EO) satellites and Global Navigation Satellite Systems (GNSS)) and ground (low-cost devices networked in the Internet of Things (IoT), 50 billion are expected within 2020) technologies.\nThe contribution deals with the general presentation of the Urban Geo Big Data, a collaborative acentric and distributed free and open source platform consisting of local data nodes for data and related service Web deploy, a visualization node for data fruition, a catalog node for data discovery, a CityGML modeler, data-rich viewers based on virtual globes, an INSPIRE metadata management system enriched with quality indicators for each dataset.For data visualization and analysis, a 3D model of the urban environment was created. CityGML is an open standard that has been thoroughly tested in the past years. One of the activities in this project was to create an Extract, Transform and Load (ETL) procedure for converting information from cartographic sources into CityGML at LOD1 (Level of Detail 1). Data are viewable by means of Cesium or Web World Wind depending on the specific examined case.\nThree use cases in five Italian cities (Turin, Milan, Padua, Rome, and Naples) are examined: 1) urban mobility; 2) land cover and soil consumption at different resolutions; 3) displacement time series. Concerning mobility data and analysis, particular attention has been given to data modeling and processing algorithms with the aim to deliver value-added information enabling standard and innovative services (Origin/Destination matrix, flows checking, routing options, etc.) based also on crowdsourced data.

To address this lack of geographic data, remote mapping and especially mapathons have played an important role in collecting geographic data in OpenStreetMap (OSM) that can be used to plan activities in areas effected by disaster or other humanitarian efforts. During mapathons, volunteers from various backgrounds get together to map a specific area using satellite imagery or aerial photographs. The expertise and motivation of these volunteers generally differ. Even though the geographic data in OSM is invaluable in cases where little to no data is available, the quality of the data collected during mapathons is often questioned. In this paper, we present our results from an evaluation of university students’ motivation for participating in mapathons and their productivity (i.e. how much data they contributed). \n\nTo achieve our aim, we hosted four mapathons for final year university students where the participants were asked to complete a short questionnaire to determine their motivations and personal opinions of the mapathon. Afterwards, the productivity for two mapathons were evaluated. Final year students enrolled in a geoinformatics module were offered extra credit for participating in the mapathons. As a result, the majority of the students participated in all four mapathons and the answers did not differ significantly between the four mapathons. \n\nOne of the main reasons mentioned, apart from extra credit, was that the participants felt a sense of humanitarianism through contributing to communities in need by assisting. Additionally, the social aspect also came through with a large percentage of the participants indicating that mapathons are fun and that they learned something new, for example by improving their digitizing skills or that humanitarian organizations need help. Participants also indicated that the tools (i.e. OSM and iD editor) were easy to use, but that the imagery is sometimes not good enough due to cloud coverage. The general productivity for two mapathons was evaluated and we found that with more experience the participants were generally more productive. A further step was taken by investigating five individuals productivity. It was clear that their productivity increased, and that they made fewer errors during the subsequent mapathons. \n\nThe results from this evaluation provided insight and knowledge that could assist mapathon organisers to create a more productive environment for participants with the hopes of encouraging them to produce high quality data. The feedback from students was clear that if they receive information about the aim of a mapathon and why the data is important, they are more motivated to produce high volumes of quality data.\n\nNone","original_language":"eng","persons":["Victoria Rautenbach","Cameron Green","Serena

es Salaam, the primary city of Tanzania is highly vulnerable to flooding even from minor Storms, floods in 2009, 2011, 2014 and 2015, caused loss of life,injury, and severely impacted diverse sectors. Dar es Salaam’s flooding problems are largely a function of inadequate storm drainage and poor waste disposal practices rather than being driven exclusively by only extreme rainfall. \nTo reduce flood risk through improved management of drain infrastructure The World Bank Tanzania funded the development of a flood risk monitoring system(Twaa Mtaro) to engage  communities in drain clean ups, to facilitate community reporting on blockages affecting the flood risk of local drainage systems and  provide municipalities with relevant data related to drain cleaning activities.\nThe development  of Twaa Mtato as a web application started May 2017 however the initial co-debase was forked from Chicago-based website for collecting and displaying resident submissions around snow emergencies called adopt-sidewalk. Twaa Mtaro core is based on ruby on rails, uses postgres/postgis for data storage and leaflet for map visualization, all geospatial data(drains data) was prepared using QGIS.\n\nNone","original_language":"eng","persons":["Edgar Vitus Mlowe","Beatrice Charles Mkumbo"],"tags":["bucharest","172","2019","General"],"view_count":46,"promoted":false,"date":"2019-08-30T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2025-05-14T11:00:05.716+02:00","length":1331,"duration":1331,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/172-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/172-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/172-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/172-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-172-development-of-a-flood-risk-monitoring-system-to-support-flood-risk-reduction-through-community-driven-drainage-cleaning-and-drain-adoption-twaa-mtaro-in-dar-es-salaam-city-","url":"https://api.media.ccc.de/public/events/123bf2f0-6f17-5563-96c7-430cfe28dd0d","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7471,"event_guid":"3c2d5b68-ca8e-5c4e-9110-59ad868cfc70","weight":2},{"event_id":7480,"event_guid":"603a5649-724a-53d7-ac20-ff7d520696d3","weight":2},{"event_id":7498,"event_guid":"b197164d-0898-54b9-9348-e8d76b0efb91","weight":2},{"event_id":7509,"event_guid":"2ecaf4b8-9654-58a3-afce-5771d68ac94f","weight":2},{"event_id":7513,"event_guid":"17f484f5-c4e2-58da-a7ec-cb18c3e85cd4","weight":1},{"event_id":7526,"event_guid":"fd5614a8-535f-5069-8f69-3a9983d37830","weight":2},{"event_id":7528,"event_guid":"92975aff-039a-5545-ba1f-1252a7690110","weight":2},{"event_id":7547,"event_guid":"a31e875c-a407-5233-a81b-d682a44e33b7","weight":2},{"event_id":7552,"event_guid":"4c2f4b81-1316-502d-870c-dc39567b782e","weight":2},{"event_id":7553,"event_guid":"9f0999f8-6941-5308-b1a8-f094c738245f","weight":2},{"event_id":7589,"event_guid":"42fe787e-4472-5c3d-a5d8-142940a0f281","weight":2},{"event_id":7595,"event_guid":"1b45aaaa-70dc-5f27-8b7b-64dc0fe409a5","weight":2},{"event_id":7611,"event_guid":"d265363a-2529-5055-80ad-05459b56a581","weight":1},{"event_id":7623,"event_guid":"d7305220-5dac-5581-bf1b-14e735c39756","weight":1},{"event_id":7635,"event_guid":"a134c0ce-1291-54b1-a56e-547284a962f0","weight":1},{"event_id":7637,"event_guid":"37fd6d99-fbed-5c0e-b209-5418299ffce5","weight":2},{"event_id":7642,"event_guid":"c51c6100-e015-53bc-8296-486d5e4e3ce7","weight":2},{"event_id":7671,"event_guid":"a38570ce-3943-5e91-aa70-1333d5d9cc48","weight":1},{"event_id":7683,"event_guid":"6c1f2dfd-1e20-5232-9dc0-f66bdc178f1f","weight":2},{"event_id":7696,"event_guid":"cf0c6d43-7a50-5d88-b6dd-db5aa818aff8","weight":2},{"event_id":7699,"event_guid":"3394a8b8-5954-531f-bbab-877ae065fcee","weight":2},{"event_id":7714,"event_guid":"33201832-16d0-59aa-b06b-93d04ed0b637","weight":2},{"event_id":7722,"event_guid":"8f2a7b79-eb9b-5eea-9cec-6878c3dc26b0","weight":2},{"event_id":7734,"event_guid":"0e88cd88-aa0a-5920-9708-e22fbf97b784","weight":2},{"event_id":7736,"event_guid":"61205921-df6b-5dff-902b-9d757f719602","weight":2},{"event_id":7738,"event_guid":"ecbd87e4-3c54-5fbe-b5fd-aefc02e7c95d","weight":1},{"event_id":7743,"event_guid":"c393e563-c11d-5111-aa92-fc579ac7ecc9","weight":1},{"event_id":7744,"event_guid":"e48d8c2a-d423-5568-8be0-45464da7dfce","weight":2},{"event_id":7758,"event_guid":"d7541c86-83fd-55c3-8843-f64e30b8aa55","weight":1}]},{"guid":"e04c27d0-8ff8-5bf4-b932-34db4e4fdf5b","title":"QGIS: No more plugins only processings","subtitle":null,"slug":"bucharest-317-qgis-no-more-plugins-only-processings","link":"https://talks.2019.foss4g.org/bucharest/talk/YLFXEV/","description":"With QGIS 3 and the processing module refactoring, it is easiest to add tools without the complexity of plugins. \n\nWe will discuss the way to add algorithms in python to QGIS and the advantage of using processing.

availability of the growing volume of environmental data from the Sentinel satellites represents a unique opportunity for the operational usage of Earth Observation (EO) for wetland inventorying, assessment and monitoring on global scale. However, it also poses major challenges in terms of data access and exploitation to achieve its full potential. GlobWetland Africa (GWA) Toolbox is an outcome of an initiative of the European Space Agency launched to facilitate the exploitation of satellite observations for the conservation, wise-use and effective management of wetlands in Africa. It is a fully free and open-source software toolbox that seamlessly combines algorithms from a number of EO and GIS tools like SNAP, QGIS, OrfeoToolbox, GRASS GIS, TauDEM together with customised Python and R scripts (e.g. for hydrological modelling) into one GUI based on QGIS. This is achieved by relying heavily on the QGIS Processing Toolbox. The algorithms are then combined into workflows, which guide less experienced users through step-by-step process of EO data analysis for wetland delineation, wetland habitat mapping, monitoring of inundation regimes and water quality as well as for mangrove mapping and river basin hydrology assessments.\n\nNone","original_language":"eng","persons":["Radoslaw Guzinski"],"tags":["bucharest","211","2019","General"],"view_count":38,"promoted":false,"date":"2019-08-30T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2025-07-05T15:30:03.807+02:00","length":1301,"duration":1301,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/211-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/211-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/211-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/211-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-211-globwetland-africa-toolbox-implementing-earth-observation-based-wetland-monitoring-capacity-in-africa","url":"https://api.media.ccc.de/public/events/87cfd947-401b-57a9-9ea2-4f6a76b8fdd6","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7466,"event_guid":"98c0417b-cdfd-57b3-9411-14f9f465f5b9","weight":1},{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":1},{"event_id":7468,"event_guid":"43d9cc0e-3fb9-55b2-a3a1-b9cfbe928e23","weight":1},{"event_id":7472,"event_guid":"d021f555-141a-58f6-a21b-a787b1c84188","weight":2},{"event_id":7484,"event_guid":"b4d6c8c6-688b-5273-aa8f-a2044128ac13","weight":1},{"event_id":7487,"event_guid":"6f1b8b15-b44a-592c-b3e9-96bd9e0fbce3","weight":1},{"event_id":7514,"event_guid":"0d63b0b4-259d-5114-8c8f-18604b514f7d","weight":1},{"event_id":7523,"event_guid":"a95cf31f-07d2-5255-bfa2-6fb38923a15f","weight":2},{"event_id":7561,"event_guid":"1125685c-9fdc-5572-89c0-8bc80c7df3e0","weight":1},{"event_id":7571,"event_guid":"ff3f8976-451e-5f00-bc69-fb2dea80b3bb","weight":1},{"event_id":7573,"event_guid":"347ab764-8ae3-58fe-87a0-18dca9880c63","weight":1},{"event_id":7579,"event_guid":"0112454d-62b2-5132-8971-73c7fdb972d0","weight":2},{"event_id":7583,"event_guid":"170c66c2-7991-5555-83b9-28702a52af03","weight":1},{"event_id":7607,"event_guid":"d0794cae-d707-584c-8879-6c438a603486","weight":2},{"event_id":7623,"event_guid":"d7305220-5dac-5581-bf1b-14e735c39756","weight":2},{"event_id":7640,"event_guid":"82b144e3-2fb0-5184-89b7-4594567be536","weight":2},{"event_id":7650,"event_guid":"eb077a88-d0d1-5a87-bc50-68bacdeaf135","weight":1},{"event_id":7656,"event_guid":"cdcc0bac-ebad-566c-b691-c54010212a86","weight":2},{"event_id":7658,"event_guid":"361e8802-42c9-542d-8fcd-05647efe3d84","weight":1},{"event_id":7666,"event_guid":"5b35bf19-e251-5dea-96f1-49e2f0f88d09","weight":1},{"event_id":7686,"event_guid":"32b1eb85-fc7e-50f8-9551-94bbb22873cf","weight":2},{"event_id":7694,"event_guid":"05466dda-8c63-57a3-a1ff-ebeff2abaa92","weight":1},{"event_id":7704,"event_guid":"d4397024-b341-5a6f-ab92-b0f157931833","weight":1},{"event_id":7724,"event_guid":"583daa21-2358-57db-8ee9-d7e1572e4c8f","weight":1},{"event_id":7726,"event_guid":"5fabfcb3-0d99-553b-a6f8-5a6119513afc","weight":2},{"event_id":7731,"event_guid":"dd3327f8-7f66-5844-bc78-9dede7aeb710","weight":1},{"event_id":7732,"event_guid":"771fc01c-25ee-5202-abbe-0b993a5e7ace","weight":1},{"event_id":7754,"event_guid":"a413689b-2102-5eec-93ef-bae111230fd3","weight":1},{"event_id":7756,"event_guid":"c4299de5-e39e-576d-93bb-7ae47fee42af","weight":2},{"event_id":7758,"event_guid":"d7541c86-83fd-55c3-8843-f64e30b8aa55","weight":1}]},{"guid":"989095dc-a2cf-5089-88da-1ae250f1cdce","title":"MAPPING FOR BETTER AND CLEAN COMMUNITIES.","subtitle":null,"slug":"bucharest-374-mapping-for-better-and-clean-communities-","link":"https://talks.2019.foss4g.org/bucharest/talk/X3T8AF/","description":"According to the recent survey that we conducted in Mukuru informal settlement here in Kenya.

Total average waste per week is 15 kg the question is where does this waste go?? Over 50% of respondents claimed that there are no efforts being made to deal with waste. Again what happens to this waste?? 18.9 % bury their waste placing it in drainage or undeveloped spaces. This is posing a great danger to our environment and beyond. During rainy seasons this waste is carried away blocking drainage and some gets its to the rivers and all the way to the sea. \nNote in Nairobi Kenya alone. We have 57 informal settlement and Kenya as a whole got 167 informal settlement. How many tonnes of garbage are produced in this areas. Which are defined as SLUMS.\n\nNone","original_language":"eng","persons":["Nicera wanjiru

Historically, analyzing large time series of satellite imagery was achieved using proprietary GIS tools or by time-intensive methods requiring substantial geospatial expertise.   CometTS requires only a web browser, Python, and dependent packages to function, obviating the GIS requirement for time series analysis and visualization.  CometTS provides a partially automated approach for analyzing a time series of satellite imagery in any user defined area of interest, then calculating relevant statistical quantities (e.g., measures of central tendency and variation), and visualizing their changes over time, all in a matter of seconds.  The overall focus of this talk will be on the development and application of CometTS for two analyses: 1) analyzing dynamic population changes over time in Africa and the Middle East and 2) ccreating the first independent estimate of the number of persons without power over time in Puerto Rico following Hurricane Maria.\n\nNone","original_language":"eng","persons":["Jake Shermeyer"],"tags":["bucharest","398","2019","General"],"view_count":115,"promoted":false,"date":"2019-08-30T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2025-06-26T20:15:03.734+02:00","length":1031,"duration":1031,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/398-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/398-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/398-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/398-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-398-comet-time-series-cometts-visualizing-temporal-trends-in-a-time-series-of-satellite-imagery-with-an-open-source-tool","url":"https://api.media.ccc.de/public/events/f1f4f54c-e816-573f-a05d-7973f9f5d48e","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7465,"event_guid":"d2b2bdd0-36fa-5ae1-aba0-a38960010e3b","weight":4},{"event_id":7469,"event_guid":"c0174aef-c7a6-5d21-8dfe-e592c5a4eff3","weight":4},{"event_id":7475,"event_guid":"49a7c19c-a42e-5058-afe1-7577dd2736c9","weight":3},{"event_id":7483,"event_guid":"54f0806e-4257-53c6-a558-e336ee584bb5","weight":3},{"event_id":7484,"event_guid":"b4d6c8c6-688b-5273-aa8f-a2044128ac13","weight":4},{"event_id":7501,"event_guid":"a4aa4222-f2ca-5e0c-94f6-4c7a3595d1a2","weight":4},{"event_id":7504,"event_guid":"c54aa667-78de-55fb-85e7-60f2eaffd2a4","weight":6},{"event_id":7505,"event_guid":"5ac07c14-e2f1-5cba-a86f-047443848af5","weight":3},{"event_id":7518,"event_guid":"8773035b-d16c-5cf3-902d-43abc7e5dab7","weight":3},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":4},{"event_id":7553,"event_guid":"9f0999f8-6941-5308-b1a8-f094c738245f","weight":2},{"event_id":7568,"event_guid":"7a848633-35e2-5b06-962e-c9cb71cf9762","weight":3},{"event_id":7579,"event_guid":"0112454d-62b2-5132-8971-73c7fdb972d0","weight":2},{"event_id":7593,"event_guid":"6a8c04d0-d372-5f16-87a2-96f537854ebc","weight":2},{"event_id":7623,"event_guid":"d7305220-5dac-5581-bf1b-14e735c39756","weight":5},{"event_id":7624,"event_guid":"69079f64-448d-55b5-9cb3-7089547c370d","weight":3},{"event_id":7652,"event_guid":"e04c27d0-8ff8-5bf4-b932-34db4e4fdf5b","weight":3},{"event_id":7664,"event_guid":"bc480eaa-8db8-54d0-bc53-32a81725f2d9","weight":2},{"event_id":7673,"event_guid":"89f564bf-e743-5086-a372-478a49b0d7ce","weight":3},{"event_id":7681,"event_guid":"a1326956-88be-5af4-b747-5cefc95e8232","weight":4},{"event_id":7695,"event_guid":"5df0ebe1-cfe2-54c4-a0c8-40e35a6de826","weight":4}]},{"guid":"2ecaf4b8-9654-58a3-afce-5771d68ac94f","title":"A framework for collaborative, open-access, and interactive GIS educational resources","subtitle":null,"slug":"bucharest-117-a-framework-for-collaborative-open-access-and-interactive-gis-educational-resources","link":"https://talks.2019.foss4g.org/bucharest/talk/HYT3HJ/","description":"Developing meaningful and interactive materials for the GIS classroom is a major challenge for educators.

A graphical user interface (GUI) makes the program user friendly. \nBesides the basic surveying calculations it is suitable for network adjustment, local coordinate transformations. digital terrain models and regression calculations. The program supports several input (electric field-books of total stations, csv, dxf) and output formats (csv, dxf, gpx, kml, vrml, ascii grid), so it can easily be inserted into user’s work-flow and can fill the gap between the surveyor’s data and GIS.\nGeoEasy is based on other open source projects among others PROJ, GNU GaMa, Triangle and available in five languages (English, German, Czech, Russian and Hungarian). The source code is available on GitHub.\nThe aim of the presentation is to make the user and developer community wider.\n\nNone","original_language":"eng","persons":["Zoltan Siki"],"tags":["bucharest","413","2019","General"],"view_count":640,"promoted":false,"date":"2019-08-29T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2025-06-23T05:30:02.405+02:00","length":1862,"duration":1862,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/413-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/413-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/413-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/413-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-413-geoeasy-free-surveying-calculations","url":"https://api.media.ccc.de/public/events/2b9d3727-6fec-552b-99b1-f240c64986b4","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7466,"event_guid":"98c0417b-cdfd-57b3-9411-14f9f465f5b9","weight":3},{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":6},{"event_id":7487,"event_guid":"6f1b8b15-b44a-592c-b3e9-96bd9e0fbce3","weight":4},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":9},{"event_id":7526,"event_guid":"fd5614a8-535f-5069-8f69-3a9983d37830","weight":4},{"event_id":7541,"event_guid":"222dc305-9e4a-5085-83c2-d78971f07dea","weight":2},{"event_id":7547,"event_guid":"a31e875c-a407-5233-a81b-d682a44e33b7","weight":2},{"event_id":7552,"event_guid":"4c2f4b81-1316-502d-870c-dc39567b782e","weight":4},{"event_id":7553,"event_guid":"9f0999f8-6941-5308-b1a8-f094c738245f","weight":5},{"event_id":7572,"event_guid":"fb951433-b271-5884-b370-a8ef56393406","weight":4},{"event_id":7574,"event_guid":"b3b2685b-8691-5c3a-bb1c-14d2038338cd","weight":2},{"event_id":7597,"event_guid":"5250fc42-6c79-5499-9029-87009757e5f5","weight":2},{"event_id":7605,"event_guid":"e8a71f0f-3fbc-5e20-9459-c17cd58bdf11","weight":1},{"event_id":7608,"event_guid":"13e2ef4d-8375-580b-a797-c54a85faa0aa","weight":2},{"event_id":7624,"event_guid":"69079f64-448d-55b5-9cb3-7089547c370d","weight":6},{"event_id":7626,"event_guid":"227ae37a-41aa-53d7-944a-2e9b7c8d99a7","weight":6},{"event_id":7669,"event_guid":"7627a093-69e4-5c72-b8b5-0f05c27ce815","weight":4},{"event_id":7674,"event_guid":"ac484924-85f6-5195-bf5b-9f689f24ef57","weight":2},{"event_id":7681,"event_guid":"a1326956-88be-5af4-b747-5cefc95e8232","weight":4},{"event_id":7695,"event_guid":"5df0ebe1-cfe2-54c4-a0c8-40e35a6de826","weight":4},{"event_id":7711,"event_guid":"ca42c4dc-9dda-5b88-abe8-f843062db935","weight":1},{"event_id":7717,"event_guid":"a68f321d-2709-5ede-8a20-aeb7f8d4a723","weight":1},{"event_id":7733,"event_guid":"0ba5c644-2353-5225-972e-6e3958f74f3e","weight":4},{"event_id":7749,"event_guid":"5117b85e-052d-5b96-bcc3-f14e953b887a","weight":5}]},{"guid":"35484d53-6b48-581d-982b-5fef3725c214","title":"The open geospatially anchored  superverse  ecosystem (Open AR Cloud)","subtitle":null,"slug":"bucharest-20-the-open-geospatially-anchored-superverse-ecosystem-open-ar-cloud-","link":"https://talks.2019.foss4g.org/bucharest/talk/7VXKFE/","description":"Augmented Reality when connected persistently to the physical world through 1:1 scale 3d real-time updated digital twins allows us to create a shared programmable space or superverse that lets us paint the world with data and let our digital lives escape from the small glowing rectangles into the real world around us and experience it together.

From an administrative view, the desire for standardized data for aggregation is very comprehensible. Producing and delivering data that complies with these requirements comes with a great set of challenges but is key to bring any such system to success.\n\nIn Switzerland the same requirements exist for standardization and aggregation. To reach this goal, a system with the name INTERLIS is developed for more than two decades already. During this time, a rich ecosystem has started to exist which builds bridges from a formal model all the way to the user interface with tools like ili2db and QGIS Model Baker.\n\nAll of this built with open source tools that are accessible for anyone.

of Big GeoData: An experiment with DINSAR deformation time series","subtitle":null,"slug":"bucharest-56-visualization-of-big-geodata-an-experiment-with-dinsar-deformation-time-series","link":"https://talks.2019.foss4g.org/bucharest/talk/3BRATM/","description":"Big Geo Data (BGD) constitute a challenge for monitoring and assessing the status of and changes in the natural and in the built environment where most of the people live.\n\nNevertheless, to convert BGD into value, we need to fill the gap existing between the current form in which BGD are represented, which conveys information understandable to scientists and experts, and the needs of not experts, decision and policy makers who could exploit information derived of BGD if adequately summarised and explicitly visualised. To this end, new methods are needed for the discovery of the relevant geodata among huge repositories, the assessment of the geodata quality, and, finally, the synthesis of BGD to provide decision makers with consistent and comprehensible information to possibly discover hidden knowledge.\n\nWithin the project “URBAN GEOmatics for Bulk data Generation, Data Assessment and Technology Awareness (URBAN GEO BIG DATA)” we are experimenting the definition and application of novel technological solutions for fostering the fruiting and synthesis of BGD by public administrators and the citizens of urban areas. Specifically, the project aims to improve the knowledge of urban areas by exploiting the fruition of the vast availability of EO data sources for soil consumption and long-term monitoring, and IoT data on mobility. A key aspect concerns the definition and implementation of novel methods for geo data dissemination through the application and extension of standard interoperable sharing protocols. \n\nIn this paper, we focus on the experiments aimed at fostering the fruition of ground deformation time series derived through the Differential SAR Interferometry (DInSAR) measurements, in urban areas (i.e., Naples and Milan city areas). In particular, the Small BAseline Subset (SBAS) technique has been applied to generate DInSAR BGD displacement time series which can be served directly by applying OGC WMS and WFS requests, but the results achieved can be hardly interpretable by non-expert decision makers.\n \nTo empower their potential fruition, we defined and implemented an automatic mechanism aimed at generating a qualitative visual temporal animation of the BGD time series of deformation synthetized by snapshot maps, generated with a reduced spatial and temporal resolution. They can be helpful for a non-expert to visually identifying at a glance the areas subject to deformations, without spending much of time analysing the single deformation time series. \n\nUseful knowledge is the mean deformation velocity map of the analysed areas. However, to follow the time evolution of the deformation, we have selected merely one single measurement per year. This is only a qualitative method for helping non-experts in identifying areas with large deformations. The paper will focus on this aspect describing its implementation details and characteristics.\n\nNone","original_language":"eng","persons":["Mariarosaria Manzo","Antonio Pepe","Pasquale

This session will cover how the project PSC operates, what is the current project roadmap, what are the main features of current stable release (2.x) as well as the future direction of the project towards pycsw 3.x that will implement search engine support as well as OGC CSW 4 in support of the emerging OGC API efforts.\n\nNone","original_language":"eng","persons":["Angelos Tzotsos","Tom Kralidis"],"tags":["bucharest","330","2019","General"],"view_count":86,"promoted":false,"date":"2019-08-29T00:00:00.000+02:00","release_date":"2019-08-29T02:00:00.000+02:00","updated_at":"2025-02-13T22:30:09.564+01:00","length":1166,"duration":1166,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/330-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/330-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/330-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/330-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-330-pycsw-project-status-2019","url":"https://api.media.ccc.de/public/events/bffc8bd9-0df8-5543-8c24-254c05092bbd","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":3},{"event_id":7468,"event_guid":"43d9cc0e-3fb9-55b2-a3a1-b9cfbe928e23","weight":3},{"event_id":7471,"event_guid":"3c2d5b68-ca8e-5c4e-9110-59ad868cfc70","weight":2},{"event_id":7473,"event_guid":"feda735f-5467-56f0-9ddf-55cefdf60199","weight":2},{"event_id":7478,"event_guid":"ae1cdec5-93fe-5638-a167-faa6e81cf9c6","weight":6},{"event_id":7481,"event_guid":"c6a74a91-9d1a-55b9-ae43-118e9abb2617","weight":4},{"event_id":7484,"event_guid":"b4d6c8c6-688b-5273-aa8f-a2044128ac13","weight":2},{"event_id":7487,"event_guid":"6f1b8b15-b44a-592c-b3e9-96bd9e0fbce3","weight":5},{"event_id":7488,"event_guid":"0a3e23aa-d593-58cd-a3a1-7991e3a3a064","weight":4},{"event_id":7492,"event_guid":"f65e1c2f-8bde-5c89-a128-e113b0b9a3f6","weight":3},{"event_id":7501,"event_guid":"a4aa4222-f2ca-5e0c-94f6-4c7a3595d1a2","weight":2},{"event_id":7505,"event_guid":"5ac07c14-e2f1-5cba-a86f-047443848af5","weight":4},{"event_id":7510,"event_guid":"ab6c65d7-f9df-563f-b9bb-e36c128e9ab4","weight":3},{"event_id":7514,"event_guid":"0d63b0b4-259d-5114-8c8f-18604b514f7d","weight":3},{"event_id":7515,"event_guid":"b744af16-2f4c-5151-bca1-91449f719965","weight":3},{"event_id":7520,"event_guid":"2e1e926d-3eaa-5fa1-83b3-1a8e001df0c6","weight":4},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":4},{"event_id":7524,"event_guid":"f58c39cb-2250-51b5-8902-d52f713c934b","weight":4},{"event_id":7525,"event_guid":"9cb9910c-3b3f-5cec-830b-24e93de3edc9","weight":3},{"event_id":7530,"event_guid":"27739ac4-67df-54da-a0f4-633bc7a9ac61","weight":2},{"event_id":7553,"event_guid":"9f0999f8-6941-5308-b1a8-f094c738245f","weight":2},{"event_id":7554,"event_guid":"20bb70f9-e0ab-5d46-9e99-71cd75e04251","weight":2},{"event_id":7560,"event_guid":"fb1d6f2b-e06d-5bfb-9ecb-0768ed3a2fb0","weight":3},{"event_id":7627,"event_guid":"1afdcbac-7132-5769-8368-712bf4a8163a","weight":4},{"event_id":7633,"event_guid":"a8aaa8da-f9ee-53ef-958c-ff6f326b3f81","weight":2},{"event_id":7749,"event_guid":"5117b85e-052d-5b96-bcc3-f14e953b887a","weight":2}]},{"guid":"a95cf31f-07d2-5255-bfa2-6fb38923a15f","title":"Geospatial open data for everyone, from global to local","subtitle":null,"slug":"bucharest-356-geospatial-open-data-for-everyone-from-global-to-local","link":"https://talks.2019.foss4g.org/bucharest/talk/NSMXGV/","description":"Reusable satellite and street maps data will be presented in this talk. Powered by open data and build with open source! Learn about the MapTiler data infrastructure and the high-resolution imagery available for Europe and the US, ready for your next project.\n\nOpen geospatial data is the new raw material every GIS expert can build upon. Free vectors and rasters are everywhere, but come in many flavors which often make them challenging to leverage. This talk aims at presenting an innovative approach for harmonizing open geospatial data using the MapTiler software tools, powered by open-source.\n\nSeveral open data use cases and processing pipelines will be presented at the global scale, from mapping the OpenStreetMap planet to color toning high volumes of open imagery. Local use cases will also be shown, including on open data released by mapping agencies, such as the Ordnance Survey or the French IGN.\n\nEmphasis will be put on creating and sharing ready to use datasets that one can easily self-host and redistribute. Description of new geodata services and cloud infrastructure will finally demonstrate how open source technology significantly adds value to open data for the benefit of all, from the community to the

the LiDAR developments, point cloud is becoming a valuable resource to build 3D models of Digital Twins, the virtual representation of a real world physical feature (object or system). Even though 3D point cloud can be more suitable to depict the real world, it requires HPC. 3D model representations help applications to quickly handle and navigate data comparing to point cloud. However, the 3D model construction of every physical feature usually necessitates expensive time and labor resources to organize and extract the features outlines by interactive manual operations. Recently, deep learning is used to derive semantic classes necessary for 3D modeling by automated classification and segmentation.\nPinSout (Point-in Space-out) is a new framework to automatically generate CityGML LOD4 from raw 3D point cloud data by using PointNet. This framework extracts each object required for 3D indoor space modeling from point cloud after learning the deep model with the annotated dataset of Standford Building Parser. After the semantic segmentation, it computes the contour of an object using PCL to augment each spatial indoor model.   Finally, the extracted objects are stored into 3D CityDB and provided as CityGML LOD4 data.\n\nNone","original_language":"eng","persons":["Kyoung-Sook Kim"],"tags":["bucharest","436","2019","General"],"view_count":132,"promoted":false,"date":"2019-08-28T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2025-01-30T17:00:08.315+01:00","length":1278,"duration":1278,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/436-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/436-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/436-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/436-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-436-pinsout-accelerating-3d-indoor-space-construction-from-point-clouds-with-deep-learning","url":"https://api.media.ccc.de/public/events/5a2c55f3-b3bc-5c4d-894a-cc7e5b887f56","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":6865,"event_guid":"ae2b1137-4425-5eee-a9c7-dfa738f7eec8","weight":1},{"event_id":7462,"event_guid":"bc0ea171-a661-56f9-a518-e32c84bbcf8b","weight":1},{"event_id":7463,"event_guid":"b771ce7c-b209-5ad2-a406-de13644ea6de","weight":1},{"event_id":7465,"event_guid":"d2b2bdd0-36fa-5ae1-aba0-a38960010e3b","weight":2},{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":1},{"event_id":7473,"event_guid":"feda735f-5467-56f0-9ddf-55cefdf60199","weight":1},{"event_id":7482,"event_guid":"89395e98-1ee1-5eee-ae26-cbaa54630177","weight":1},{"event_id":7484,"event_guid":"b4d6c8c6-688b-5273-aa8f-a2044128ac13","weight":1},{"event_id":7486,"event_guid":"b1b0dc99-0069-587a-867f-07b777daf77a","weight":1},{"event_id":7488,"event_guid":"0a3e23aa-d593-58cd-a3a1-7991e3a3a064","weight":1},{"event_id":7502,"event_guid":"22e35ec7-d84e-5a95-a490-adc14715792b","weight":1},{"event_id":7504,"event_guid":"c54aa667-78de-55fb-85e7-60f2eaffd2a4","weight":3},{"event_id":7508,"event_guid":"90c767f8-cbe3-587d-a2b8-ee879b7e8b45","weight":1},{"event_id":7512,"event_guid":"88c1d544-049b-5622-b197-03b8894a39f7","weight":1},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":1},{"event_id":7526,"event_guid":"fd5614a8-535f-5069-8f69-3a9983d37830","weight":1},{"event_id":7547,"event_guid":"a31e875c-a407-5233-a81b-d682a44e33b7","weight":1},{"event_id":7548,"event_guid":"8ca1b4b6-ee0c-5102-ab95-a978cd3b4d8c","weight":1},{"event_id":7550,"event_guid":"53494dbe-b19b-5e77-a2d1-9cb5a6d5447d","weight":2},{"event_id":7552,"event_guid":"4c2f4b81-1316-502d-870c-dc39567b782e","weight":1},{"event_id":7558,"event_guid":"175e2989-1005-5266-8928-9bb1247bf423","weight":1},{"event_id":7563,"event_guid":"eac1e444-e3c2-52b6-aea9-c14f53a6ae4b","weight":3},{"event_id":7572,"event_guid":"fb951433-b271-5884-b370-a8ef56393406","weight":1},{"event_id":7575,"event_guid":"bcca12c5-309f-588b-a67e-c5f1fc31f998","weight":2},{"event_id":7576,"event_guid":"88c4c363-fafc-52a3-9ddf-60753caed575","weight":1},{"event_id":7579,"event_guid":"0112454d-62b2-5132-8971-73c7fdb972d0","weight":1},{"event_id":7585,"event_guid":"3e149633-f405-5e9b-850c-b0934537b6d8","weight":1},{"event_id":7608,"event_guid":"13e2ef4d-8375-580b-a797-c54a85faa0aa","weight":1},{"event_id":7614,"event_guid":"7347a409-8f11-53a7-b855-39fcf0d8c2ae","weight":1},{"event_id":7615,"event_guid":"ba01c485-9187-5f92-adbe-fb00f97bfe8d","weight":1},{"event_id":7617,"event_guid":"5eaf093f-4b8d-5455-9a6c-252d78a94e9c","weight":1},{"event_id":7619,"event_guid":"21ffa487-5dfd-57d3-acce-8fd048ead7cf","weight":1},{"event_id":7623,"event_guid":"d7305220-5dac-5581-bf1b-14e735c39756","weight":1},{"event_id":7627,"event_guid":"1afdcbac-7132-5769-8368-712bf4a8163a","weight":1},{"event_id":7641,"event_guid":"d5b00dcc-d898-5a3a-bc8f-8e62d492bf4e","weight":1},{"event_id":7645,"event_guid":"efd996c1-5096-5b23-bf42-3dd6818dc072","weight":1},{"event_id":7646,"event_guid":"1e986309-98ba-5840-b70e-300ff54d78bc","weight":1},{"event_id":7662,"event_guid":"a8fbf537-cbe1-5f17-aa73-97d64132f660","weight":1},{"event_id":7667,"event_guid":"4bc8bbe5-cb04-5a2b-b441-a696be055948","weight":1},{"event_id":7672,"event_guid":"1c58bd3e-15f6-51a3-af44-9d6a75f31556","weight":1},{"event_id":7697,"event_guid":"971041ce-c63e-5464-a25b-aba96b14d500","weight":1},{"event_id":7722,"event_guid":"8f2a7b79-eb9b-5eea-9cec-6878c3dc26b0","weight":1},{"event_id":7743,"event_guid":"c393e563-c11d-5111-aa92-fc579ac7ecc9","weight":2},{"event_id":7744,"event_guid":"e48d8c2a-d423-5568-8be0-45464da7dfce","weight":2},{"event_id":7758,"event_guid":"d7541c86-83fd-55c3-8843-f64e30b8aa55","weight":1}]},{"guid":"4c2f4b81-1316-502d-870c-dc39567b782e","title":"OpenLayers 6 -

What should have been a peaceful rest after a lengthy refactoring in version 5 did in fact end up being an involved rewrite of its rendering code: better **performance**, nicer **vector tiles**, smoother **WebGL**, more options and even some Mapbox goodness in there.\n\nIn this talk we will take a quick tour of all the new stuff in OpenLayers and talk about the *why*s and *how*s, as well as what lies ahead of us.

Mapbox has recently added custom layers to its set of allowed layer types. The custom layer allows developers to render custom data while directly using the the WebGL render engine.\n\nWe have implemented mapbox-gl custom layers for rendering 3D tiles and point cloud data. This enables the already feature rich Mapbox rendering engine to be combined with web-visualization of true geographic 3D data directly from OGC formats. An advantage of this is that you can use the mapbox navigation and base-layer rendering while at the same time complex 3D objects directly to your web browser.  in a way similar to vectortiles in 2D space. \n\nIn this talk we will demonstrate an implementation of a 3D Tiles viewer as a Mapbox GL JS custom layer. WebGL rendering is implemented using three.js. This addition enables you to add a 3D-tiles layer with true 3D objects on top of your existing mapbox implementation just as easy as you would be adding a vector-tile service.\n\nWe will discuss some technical issues we have encountered, give examples on how you can use it and show an extensive demonstration of what you can do with it.\n\nNone","original_language":"eng","persons":["Tom van Tilburg

This talk builds on the lessons learned by the Open Source Geospatial Foundation in twelve years helping project teams and building the foss4g community.\n\nThis presentations looks at the core values that OSGeo as an organization ask projects to adopt. We will discuss why we consider these factors critical to success, and practical ways they can be applied to your project. \n\n* To introduce OSGeo principles we will look at what is required to list an open source project on our website.\n* Our community program is used to explore how these principles are applied in practice.\n* Unpack how each principles is realized in the OSGeo incubation program, using examples of “OSGeo Projects” to explore different ways of achieving success.\n\nWe invite project teams interested in succeeding with open source to attend this talk (and list your project on the OSGeo project directory after the presentation).\n\nIf you are new to open source, or cautious, consider this talk an introduction to some of the risk factors associated with open source and community work - and mitigation steps to consider.\n\nNone","original_language":"eng","persons":["Jody

presentation will provide the attendee with an introduction to data processing in GeoServer by means of WPS, rendering transformations and SQL views, describing real applications and how these facilities were used in them. We'll start with the basic WPS capabilities, showing how to build processing request based on existing processes and how to build new processes leveraging scripting languages, and introducing unique GeoServer integration features, showing how processing can seamlessly integrate directly in the GeoServer data sources and complement existing services.\n\nMoreover, we will show how to integrate on the fly processing in WMS requests, achieving high performance data displays without having to pre-process the data in advance, and allowing the caller to interactively choose processing parameters.\n\nWhile the above shows how to make GeoServer perform the work, the processing abilities of spatial databases should not be forgotten, so we will show how certain classes of processing can be achieved directly in the database.\n\nAt the end the attendee will be able to easily issue WPS requests both for Vectors and Rasters to GeoServer through the WPS Demo Builder, enrich SLDs with on-the-fly rendering transformations.\n\nNone","original_language":"eng","persons":["Mauro Bartolomeoli","Andrea Aime"],"tags":["bucharest","195","2019","General"],"view_count":146,"promoted":false,"date":"2019-08-28T00:00:00.000+02:00","release_date":"2019-08-29T02:00:00.000+02:00","updated_at":"2024-03-16T21:45:07.331+01:00","length":1607,"duration":1607,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/195-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/195-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/195-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/195-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-195-crunching-data-in-geoserver-mastering-rendering-transformations-wps-processes-and-sql-views-","url":"https://api.media.ccc.de/public/events/7b9c8b02-7d33-5172-b0ea-841a26d389b0","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7466,"event_guid":"98c0417b-cdfd-57b3-9411-14f9f465f5b9","weight":11},{"event_id":7480,"event_guid":"603a5649-724a-53d7-ac20-ff7d520696d3","weight":8},{"event_id":7517,"event_guid":"ef1a3ce2-61bf-53e1-8f97-acb738c219f9","weight":10},{"event_id":7530,"event_guid":"27739ac4-67df-54da-a0f4-633bc7a9ac61","weight":9},{"event_id":7580,"event_guid":"c068c48a-bbac-5dda-bb74-e1e56672cc12","weight":1},{"event_id":7740,"event_guid":"503efde4-1e72-51f5-b508-4ca91a364086","weight":2}]},{"guid":"87692512-45dd-5b7b-9456-62d1a04a185e","title":"Integration of GIS in non-GIS applications","subtitle":null,"slug":"bucharest-134-integration-of-gis-in-non-gis-applications","link":"https://talks.2019.foss4g.org/bucharest/talk/ATYAYW/","description":"In GIS software development there is often a need to seamlessly integrate a simple or more complex GIS solutions into new or existing non-GIS applications. Depending on the non-GIS system, number of different integration technologies are used. From communication standpoint there is a client-side integration based on WebSocket technology, JS API or using more recent technologies like custom elements (e.g. Angular Elements). From complexity and functionality standpoint there is an option to use custom developed lightweight GIS or full featured GIS viewer/editor based on our own IGEO platform.

GRASS locations, mapsets, vector and raster data as well as spatio-temporal data are available as resources to allow their management and visualization. With the existing (e.g. Landsat) and also recently emerging (Copernicus Sentinel) big geodata pools which are growing day by day, it is designed to follow the purpose of bringing algorithm to cloud geodata. It helps to prepare, analyse and provide a large amount of geoinformation without the need to have know-how of the data, of analysis, appropriate software (for automatisation) or scalable hardware resources.\nSome of the features are persistent and ephemeral processing, user management to limit e.g. pixels, processes and duration of calculations as well as logging of API calls and used resources by each user. Another advantage is its easy deployment with docker. When deployed in a cloud based environment with OpenShift or docker-swarm, the integrated load balancer handles a cluster automatically.\n\nFollowing the spirit of free and open software, we are proud to have emerged as an OSGeo community project and look forward to enlarge the actinia community.\n\nNone","original_language":"eng","persons":["Carmen Tawalika","Markus Neteler"],"tags":["bucharest","229","General"],"view_count":91,"promoted":false,"date":"2019-08-28T00:00:00.000+02:00","release_date":"2019-08-28T02:00:00.000+02:00","updated_at":"2024-12-16T15:00:05.190+01:00","length":1138,"duration":1138,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/229-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/229-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/229-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/229-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-229-grass-gis-in-the-cloud-actinia-geoprocessing","url":"https://api.media.ccc.de/public/events/a5a5b7b3-060a-582a-b1b2-f626a681e79b","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7465,"event_guid":"d2b2bdd0-36fa-5ae1-aba0-a38960010e3b","weight":5},{"event_id":7466,"event_guid":"98c0417b-cdfd-57b3-9411-14f9f465f5b9","weight":4},{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":4},{"event_id":7484,"event_guid":"b4d6c8c6-688b-5273-aa8f-a2044128ac13","weight":3},{"event_id":7520,"event_guid":"2e1e926d-3eaa-5fa1-83b3-1a8e001df0c6","weight":3},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":4},{"event_id":7524,"event_guid":"f58c39cb-2250-51b5-8902-d52f713c934b","weight":3},{"event_id":7546,"event_guid":"c2504e4b-02f0-5347-92b9-bcd1d86d7df4","weight":3},{"event_id":7609,"event_guid":"64785b52-3c01-587f-ad49-224968c337df","weight":3},{"event_id":7670,"event_guid":"87692512-45dd-5b7b-9456-62d1a04a185e","weight":3}]},{"guid":"c0ebaf1b-03d8-53f4-81d1-b5b306e93c60","title":"BruGIS Data Management (BDM) : QGIS plugins to manage and edit data","subtitle":null,"slug":"bucharest-131-brugis-data-management-bdm-qgis-plugins-to-manage-and-edit-data","link":"https://talks.2019.foss4g.org/bucharest/talk/T7QHTA/","description":"BruGIS® is a cartographic tool developed by a public interest organization (Urban.brussels) and used for the management and planning of the territory in the Brussels Capital Region.

We’ll be able to create a new user and assign him editing rights on a layer. Then edit the layer allowed, modify, validate (topological) and finally submit it. Lastly, we’ll publish the modified and validated layer.\nThe path of the modified table will be followed through the DB environment of BruGIS. The organization of data synchronization through the three environments (production, staging, diffusion) will be briefly addressed.\n\nThe purpose of this demonstration is not to go into the technical details of the production flow but rather to exemplify the use of Open Source technologies within the framework of the daily management of the urban data in a public administration.\n\nNone","original_language":"eng","persons":["BruGIS"],"tags":["bucharest","131","2019","General"],"view_count":58,"promoted":false,"date":"2019-08-29T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2025-03-14T17:30:05.736+01:00","length":1083,"duration":1083,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/131-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/131-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/131-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/131-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-131-brugis-data-management-bdm-qgis-plugins-to-manage-and-edit-data","url":"https://api.media.ccc.de/public/events/c0ebaf1b-03d8-53f4-81d1-b5b306e93c60","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7466,"event_guid":"98c0417b-cdfd-57b3-9411-14f9f465f5b9","weight":1},{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":5},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":6},{"event_id":7550,"event_guid":"53494dbe-b19b-5e77-a2d1-9cb5a6d5447d","weight":4},{"event_id":7575,"event_guid":"bcca12c5-309f-588b-a67e-c5f1fc31f998","weight":4},{"event_id":7582,"event_guid":"95c65e38-a93e-5306-a9c6-b1cdc197bb58","weight":4},{"event_id":7595,"event_guid":"1b45aaaa-70dc-5f27-8b7b-64dc0fe409a5","weight":5},{"event_id":7608,"event_guid":"13e2ef4d-8375-580b-a797-c54a85faa0aa","weight":4},{"event_id":7652,"event_guid":"e04c27d0-8ff8-5bf4-b932-34db4e4fdf5b","weight":3},{"event_id":7669,"event_guid":"7627a093-69e4-5c72-b8b5-0f05c27ce815","weight":4},{"event_id":7674,"event_guid":"ac484924-85f6-5195-bf5b-9f689f24ef57","weight":4},{"event_id":7681,"event_guid":"a1326956-88be-5af4-b747-5cefc95e8232","weight":3},{"event_id":7695,"event_guid":"5df0ebe1-cfe2-54c4-a0c8-40e35a6de826","weight":5},{"event_id":7743,"event_guid":"c393e563-c11d-5111-aa92-fc579ac7ecc9","weight":1},{"event_id":7759,"event_guid":"2dbbceca-916a-5619-8d57-6bd9f57db57a","weight":3}]},{"guid":"60e9b22b-78f2-5213-a4bc-76adada4fa2a","title":"The Open Data Cube Sandbox","subtitle":null,"slug":"bucharest-140-the-open-data-cube-sandbox","link":"https://talks.2019.foss4g.org/bucharest/talk/CF7LYC/","description":"FrontierSI have been working with the Open Data Cube Community to develop simpler ways of running the ODC, and one of these is the ‘Sandbox’ project, where we have built a pre-configured ODC instance as a reference deployment. \n\nThe Sandbox aims to provide developers, data scientists, decision makers and everyone else a way to learn about remote sensing, the ODC generally, or about the various applications that earth observation data can be used in. The use of Docker, Kubernetes, the ODC and Dask enables for a scalable environment that can run non-trivial workloads. The ODC Sandbox is as easy to use as visiting a website, it's powered by vast quantities of open data, it’s available now and the architecture is open, so you can build one yourself too. \n\nThis presentation will briefly introduce the ODC project and will then discuss the Sandbox, how it is structured and what is required to get started. The presentation concludes with demonstrations of a number of use cases and applications of the ODC that are available in the Sandbox in addition to future

can be presented as vector or raster layers. In open source world, GDAL provides a comprehensive set of tools to interact with such datasets. But vector or raster is not always a suitable description of real world features. Data from oceanography, metrology, hydrology, etc often have multiple components at each location on an irregular structured mesh. A **mesh** can a collection of vertices, edges and faces in 2D or 3D space: - vertices - XY(Z) points (in the layer's coordinate reference system) - edges - connect pairs of vertices - faces - sets of edges forming a closed shape - typically triangles or quadrilaterals (quads), rarely polygons with higher number of vertices ![Example of mesh](https://user-images.githubusercontent.com/193367/38030812-f6c4f174-3299-11e8-91ed-30684ceae715.png) Mesh gives us information about the spatial structure.

The back-ends run their own API instance, translating the http requests to their environment. The front end API implementation can serve different languages (R, Python, Javascript) on the client side. The openEO project has foreseen that APIs are implemented with an open source license (Apache 2.0).\n\nA number of back-ends are already available that are compatible with this suggested openEO standard. For instance, within the Joint Research Centre (JRC) of the European Commission, an API implemented in Python is being developed that can discover and process geospatial data collections available in the JRC Earth Observation Data and Processing Platform (JEODPP). For the back-end, an in-house library is being developed under the European Union Public Licence (EUPL). In this presentation, we will highlight the openEO concepts and focus in particular on the JRC back-end implementation details.\n\nNone","original_language":"eng","persons":["Pieter Kempeneers"],"tags":["bucharest","344","2019","General"],"view_count":42,"promoted":false,"date":"2019-08-30T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2025-03-21T17:00:05.178+01:00","length":1554,"duration":1554,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/344-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/344-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/344-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/344-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-344-implementing-an-openeo-compliant-back-end-for-processing-data-cubes-on-the-jeodpp","url":"https://api.media.ccc.de/public/events/bd73f1db-b0ba-582e-b515-bc1e1bc10f7d","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":5436,"event_guid":"c385ad1d-5cfd-55bd-afa1-a453f9e338c3","weight":1},{"event_id":5440,"event_guid":"8dee6863-f2ab-5d48-9260-11d017abb870","weight":1},{"event_id":7489,"event_guid":"7c66788d-24a7-5951-865f-c85816356441","weight":1},{"event_id":7493,"event_guid":"dd3738e7-3aa6-580a-a526-d9087b930c84","weight":1},{"event_id":7498,"event_guid":"b197164d-0898-54b9-9348-e8d76b0efb91","weight":1},{"event_id":7513,"event_guid":"17f484f5-c4e2-58da-a7ec-cb18c3e85cd4","weight":1},{"event_id":7516,"event_guid":"edcad3ee-627e-5a69-8432-c12c4a09173c","weight":1},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":1},{"event_id":7528,"event_guid":"92975aff-039a-5545-ba1f-1252a7690110","weight":1},{"event_id":7543,"event_guid":"7b40d7a8-7350-54ce-9809-87c5b0ee912f","weight":1},{"event_id":7576,"event_guid":"88c4c363-fafc-52a3-9ddf-60753caed575","weight":1},{"event_id":7581,"event_guid":"f3a8dd85-9308-553a-928d-bfd47824fbd7","weight":1},{"event_id":7587,"event_guid":"1dac21fe-e493-541b-8e5f-ba1c1f15db2c","weight":1},{"event_id":7591,"event_guid":"3a4e2ca2-c4f2-5516-8f69-01be68113f22","weight":1},{"event_id":7599,"event_guid":"6dcfbcee-a817-50dc-a293-f200b4a15b71","weight":1},{"event_id":7601,"event_guid":"764ef9d5-9a23-5351-ba0c-98e518d7cb50","weight":1},{"event_id":7621,"event_guid":"8e5e286c-0e3c-5c18-9122-dee8e92752cc","weight":1},{"event_id":7631,"event_guid":"989095dc-a2cf-5089-88da-1ae250f1cdce","weight":1},{"event_id":7640,"event_guid":"82b144e3-2fb0-5184-89b7-4594567be536","weight":1},{"event_id":7643,"event_guid":"63e1996e-b296-55cb-9fd6-4e4d22e878f6","weight":1},{"event_id":7650,"event_guid":"eb077a88-d0d1-5a87-bc50-68bacdeaf135","weight":1},{"event_id":7678,"event_guid":"c9058144-0344-5cdd-9e8d-228d9a6443f3","weight":1},{"event_id":7689,"event_guid":"6a5482fd-2b09-5bea-bea5-b48ba7e33cf3","weight":1},{"event_id":7693,"event_guid":"7b831cc0-2092-52d2-bb54-f219e39a666f","weight":1},{"event_id":7700,"event_guid":"a45f513c-23e0-512d-a69c-8163e5edf0d8","weight":1},{"event_id":7708,"event_guid":"f41c767d-1f3d-5e46-a477-1a9dde63e146","weight":1},{"event_id":7714,"event_guid":"33201832-16d0-59aa-b06b-93d04ed0b637","weight":1},{"event_id":7715,"event_guid":"664da34a-88d9-57c5-8b88-cdbfca55029b","weight":1},{"event_id":7719,"event_guid":"e303b05d-9930-593f-8184-9233c04f6ec7","weight":1},{"event_id":7724,"event_guid":"583daa21-2358-57db-8ee9-d7e1572e4c8f","weight":1},{"event_id":7727,"event_guid":"812560ad-8181-524d-a843-95523fed1e81","weight":1},{"event_id":7728,"event_guid":"19bd2191-55cb-5597-9c69-b05fbce25eea","weight":1},{"event_id":7734,"event_guid":"0e88cd88-aa0a-5920-9708-e22fbf97b784","weight":1},{"event_id":7736,"event_guid":"61205921-df6b-5dff-902b-9d757f719602","weight":1},{"event_id":7737,"event_guid":"a8593987-dcf7-54ec-abef-5fda903cd5a6","weight":1},{"event_id":7738,"event_guid":"ecbd87e4-3c54-5fbe-b5fd-aefc02e7c95d","weight":1},{"event_id":7739,"event_guid":"9fb4a987-3f98-530a-9177-41099f13ddef","weight":1},{"event_id":7748,"event_guid":"753ef9d6-c39e-5cdb-88c5-1ebe4760f70a","weight":1},{"event_id":7751,"event_guid":"bb1806af-1579-5ee7-916e-099ef1bb74f1","weight":1}]},{"guid":"3c2d5b68-ca8e-5c4e-9110-59ad868cfc70","title":"Introduction to MapStore, mashups made simple","subtitle":null,"slug":"bucharest-194-introduction-to-mapstore-mashups-made-simple","link":"https://talks.2019.foss4g.org/bucharest/talk/RZFC33/","description":"MapStore is the Open Source product for creating, saving and sharing in a simple and intuitive way maps and mashups created selecting contents from public services like Google Maps and OpenStreetMap or other servers implementing OGC and ISO protocols.

The biggest challenge is no more to get the data; but to structure it, analyze it, extract new information from it, and design clever representations in order to visualize it.\n\nThis presentation will focus on a recent open source study made by Oslandia about bike-sharing systems in France. Our dev stack is largely based on Python tools, from back-end (a data pipeline designed with Luigi) to front-end (with Flask API and web application).\n\nThe most important data processing steps will be detailed, and a particular attention will be paid to inherent machine learning problems, like bike stand classification, or bike availability prediction. To that matter, we target a better comprehension of urban areas, and value creation for bike-sharing system users.\n\nA live demo of the web application will end the presentation.\n\nNone","original_language":"eng","persons":["Raphaël Delhome"],"tags":["bucharest","369","2019","General"],"view_count":75,"promoted":false,"date":"2019-08-28T00:00:00.000+02:00","release_date":"2019-08-29T02:00:00.000+02:00","updated_at":"2025-04-27T04:15:02.675+02:00","length":1551,"duration":1551,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/369-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/369-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/369-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/369-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-369-shared-bike-services-from-open-data-platforms-to-a-dataviz-application","url":"https://api.media.ccc.de/public/events/22e35ec7-d84e-5a95-a490-adc14715792b","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7466,"event_guid":"98c0417b-cdfd-57b3-9411-14f9f465f5b9","weight":2},{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":1},{"event_id":7471,"event_guid":"3c2d5b68-ca8e-5c4e-9110-59ad868cfc70","weight":2},{"event_id":7473,"event_guid":"feda735f-5467-56f0-9ddf-55cefdf60199","weight":1},{"event_id":7477,"event_guid":"9227fcf3-b7b2-5a7a-b135-3e7a18341a82","weight":1},{"event_id":7478,"event_guid":"ae1cdec5-93fe-5638-a167-faa6e81cf9c6","weight":2},{"event_id":7487,"event_guid":"6f1b8b15-b44a-592c-b3e9-96bd9e0fbce3","weight":1},{"event_id":7514,"event_guid":"0d63b0b4-259d-5114-8c8f-18604b514f7d","weight":1},{"event_id":7519,"event_guid":"33229e10-d954-564b-bb6f-f48e5b5d3882","weight":1},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":2},{"event_id":7536,"event_guid":"9f921eab-53c5-5ce7-9489-45a586162248","weight":1},{"event_id":7537,"event_guid":"14a1b81d-47c2-560c-9525-26e35f4caf54","weight":1},{"event_id":7553,"event_guid":"9f0999f8-6941-5308-b1a8-f094c738245f","weight":1},{"event_id":7554,"event_guid":"20bb70f9-e0ab-5d46-9e99-71cd75e04251","weight":1},{"event_id":7560,"event_guid":"fb1d6f2b-e06d-5bfb-9ecb-0768ed3a2fb0","weight":3},{"event_id":7579,"event_guid":"0112454d-62b2-5132-8971-73c7fdb972d0","weight":4},{"event_id":7607,"event_guid":"d0794cae-d707-584c-8879-6c438a603486","weight":2},{"event_id":7608,"event_guid":"13e2ef4d-8375-580b-a797-c54a85faa0aa","weight":1},{"event_id":7610,"event_guid":"08454950-b5fe-59f1-9a94-2f51780aef74","weight":2},{"event_id":7612,"event_guid":"20bb8f65-038d-5e73-bba1-186f5b40f548","weight":3},{"event_id":7669,"event_guid":"7627a093-69e4-5c72-b8b5-0f05c27ce815","weight":3},{"event_id":7681,"event_guid":"a1326956-88be-5af4-b747-5cefc95e8232","weight":1},{"event_id":7702,"event_guid":"a3427cdb-d2e7-5f6d-bd1e-536a2f9f34fb","weight":2},{"event_id":7749,"event_guid":"5117b85e-052d-5b96-bcc3-f14e953b887a","weight":5},{"event_id":7755,"event_guid":"f651ccfa-c224-5cfa-b76b-f7b44b4ef563","weight":3},{"event_id":7756,"event_guid":"c4299de5-e39e-576d-93bb-7ae47fee42af","weight":4}]},{"guid":"7627a093-69e4-5c72-b8b5-0f05c27ce815","title":"Custom workflows in QGIS thanks to Python - a non technical introduction","subtitle":null,"slug":"bucharest-182-custom-workflows-in-qgis-thanks-to-python-a-non-technical-introduction","link":"https://talks.2019.foss4g.org/bucharest/talk/WTRBY8/","description":"This talk introduces the integration and possibilities of Python within and around QGIS in its latest version.

The project conducts developments of manual and capacity building of WASAC, Districts and Private Operators.\n\u003cbr\u003e\nCurrently, most of countries focus SDGs to achieve 100% water access by 2030. Because of that, it is very necessary to collect and analyse the GIS inventory data for water supply management, especially planning and improvement of operation and maintenance. \n\u003cbr\u003e\nNow WASAC has started to map all of water facilities data in rural area under support of RWASOM since July 2018.

Destination travel is a popular way to experience the world for millions of people. Until now, little research has been conducted to establish what this type of user might actually need in a map-centric application. Most current approaches do not emphasize the role of space and place in travel preparation to help users understand the spatial dimensions of their travel plans. In addition, most of the available trip planning systems are proprietary in nature. Our work seeks to develop an application that goes beyond providing support for simple itinerary creation. We present results from a user survey to assess key spatially-supported travel task needs and design preferences.

The core of the model is a raster based cell-by-cell mass balance calculation which includes the key hydrological processes, such as effective precipitation, surface runoff and stream network routing. Effective precipitation, the forcing of the runoff and erosion processes, is reduced by a surface retention and an infiltration. Surface runoff consists of two components: slower sheet and concentrated rapid rill flow. Stream network routing is performed line-by-line in user predefined polyline layer. SMODERP is a long-term running project driven by the Department of Landscape Water Conservation at the Czech Technical University in Prague. At the beginning SMODERP has been developed as a surface runoff simulated by profile model (1D). Later the model has been redesigned using spatially distributed method. This version is named SMODERP2D. Ongoing development (https://github.com/storm-fsv-cvut/smoderp2d) is focused on obtaining parameters of the hydrological models, incorporating new infiltration and flow routing routines, and conceptualization of a rill flow and rill development. The model belongs to a family of so called GIS-based hydrological models utilizing capabilities of GIS software for geodata processing. Importantly, the SMODERP2D project is currently entering the open source world. Originally the model could be run only in proprietary Esri ArcGIS platform. A new version of the model presented by this contribution adds support for two key open source GIS platforms, GRASS GIS and QGIS. A newly developed GRASS module and QGIS plugin significantly increases accessibility of the SMODERP2D model for research purposes and also for engineering practice. Middle scale distributed hydrological models often encounter with a high computation costs and long model runtime. Long runtime is caused by high resolution input data which is easily available nowadays. The project also includes an experimental version of the SMODERP2D model enabling the parallelization of computations. This parallelization is done using TensorFlow, and its goal is to decrease the time needed for its run. It is supported by both CPU and GPU. Parallelization of computations is an important step towards providing SMODERP2D web processing services in order to allow quick and easy integration to highly specialized platforms such as Atlas Ltd.

A brand-new world comprising the build up of a major SDI, lots of geodata and heavy geoprocessing is needed to substitute previous manual tasks and to sustain the goals.  \n  \nThink about a project, that will be developed by +10 companies, each with its own frameworks, procedures and deployment workflows. To succeed, you'll need more than confidence in the team. This is also because of other complicating factors like IT security, large data pipelines or ever-changing IT infrastructure.  \n  \nThis is where DevOps and AGILE practices came to the rescue. It gave a structure and a common understanding of the workflows to every project member, as well provided enough automation and flexibility to adjust to the constant changes the project undergone.  \n  \nIn this talk, we’ll present the key challenges and how DTAG and the team of the FTTH-Factory successfully implements agile and DevOps workflows for the project. If we’re brave, we’ll do DevOps on stage.\n\nNone","original_language":"eng","persons":["Markus Neteler","Emmanuel Belo","Torsten Drey","Marc Jansen"],"tags":["bucharest","346","2019","General"],"view_count":37,"promoted":false,"date":"2019-08-28T00:00:00.000+02:00","release_date":"2019-08-29T02:00:00.000+02:00","updated_at":"2024-10-26T20:45:02.424+02:00","length":1723,"duration":1723,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/346-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/346-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/346-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/346-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-346-when-building-maintaining-continuously-improving-a-sdi-isn-t-enough-devops-processes-to-the-rescue","url":"https://api.media.ccc.de/public/events/14a1b81d-47c2-560c-9525-26e35f4caf54","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7274,"event_guid":"f8665fe1-8ffa-4ec0-8924-17933c87ebcf","weight":1},{"event_id":7464,"event_guid":"a5a5b7b3-060a-582a-b1b2-f626a681e79b","weight":2},{"event_id":7466,"event_guid":"98c0417b-cdfd-57b3-9411-14f9f465f5b9","weight":3},{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":1},{"event_id":7484,"event_guid":"b4d6c8c6-688b-5273-aa8f-a2044128ac13","weight":2},{"event_id":7502,"event_guid":"22e35ec7-d84e-5a95-a490-adc14715792b","weight":1},{"event_id":7514,"event_guid":"0d63b0b4-259d-5114-8c8f-18604b514f7d","weight":1},{"event_id":7517,"event_guid":"ef1a3ce2-61bf-53e1-8f97-acb738c219f9","weight":2},{"event_id":7518,"event_guid":"8773035b-d16c-5cf3-902d-43abc7e5dab7","weight":1},{"event_id":7520,"event_guid":"2e1e926d-3eaa-5fa1-83b3-1a8e001df0c6","weight":2},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":2},{"event_id":7523,"event_guid":"a95cf31f-07d2-5255-bfa2-6fb38923a15f","weight":1},{"event_id":7524,"event_guid":"f58c39cb-2250-51b5-8902-d52f713c934b","weight":4},{"event_id":7534,"event_guid":"3fc26cc4-962e-5f27-a92b-c01e86d12100","weight":2},{"event_id":7542,"event_guid":"7e354528-0b5a-512d-be47-bdc7447bb93b","weight":2},{"event_id":7546,"event_guid":"c2504e4b-02f0-5347-92b9-bcd1d86d7df4","weight":3},{"event_id":7552,"event_guid":"4c2f4b81-1316-502d-870c-dc39567b782e","weight":3},{"event_id":7553,"event_guid":"9f0999f8-6941-5308-b1a8-f094c738245f","weight":1},{"event_id":7559,"event_guid":"69de3e04-de0f-5325-9862-023143b3252b","weight":1},{"event_id":7573,"event_guid":"347ab764-8ae3-58fe-87a0-18dca9880c63","weight":1},{"event_id":7579,"event_guid":"0112454d-62b2-5132-8971-73c7fdb972d0","weight":2},{"event_id":7609,"event_guid":"64785b52-3c01-587f-ad49-224968c337df","weight":5},{"event_id":7612,"event_guid":"20bb8f65-038d-5e73-bba1-186f5b40f548","weight":1},{"event_id":7629,"event_guid":"43e2163d-d0f7-5b45-945b-25dd8c57118b","weight":1},{"event_id":7632,"event_guid":"99a39bf7-5c95-5bc3-947a-55e28aa0a042","weight":1},{"event_id":7710,"event_guid":"9bce8e1a-0dc8-5c82-977c-23dccd115e89","weight":2},{"event_id":7733,"event_guid":"0ba5c644-2353-5225-972e-6e3958f74f3e","weight":2},{"event_id":7743,"event_guid":"c393e563-c11d-5111-aa92-fc579ac7ecc9","weight":2},{"event_id":7757,"event_guid":"08e7e90e-7da4-524d-8875-b38d23b6c1cf","weight":1}]},{"guid":"edcad3ee-627e-5a69-8432-c12c4a09173c","title":"Using Open Street Mapping to map Incidence of Malaria among Vulnerable People of Luano District, central Zambia","subtitle":null,"slug":"bucharest-42-using-open-street-mapping-to-map-incidence-of-malaria-among-vulnerable-people-of-luano-district-central-zambia","link":"https://talks.2019.foss4g.org/bucharest/talk/DQP7QK/","description":"Using Open Street Mapping to map Incidence of Malaria among Vulnerable People of Luano District, central Zambia\nThis is a Research project for the YouthMappers.\nThis study investigates the incidence of malaria among the vulnerable people living in a remote area of Zambia.

seas and oceans are substantially polluted by conventional and chemical munitions from the two World Wars. They were introduced by different pathways e.g. mine laying, naval battles and shipwrecks. However, the biggest amount originates from large scale ammunition dumping activities after World War II. The goal of the OpenSource based Ammunition Cadastre Sea is therefore data acquisition, assessment and monitoring of the status of ammunitions in our seas and oceans and their effects.\n\nAlmost all relevant data in this field has a spatial context. Therefore the idea is capturing, visualizing and analyzing everything that is related to ammunition in the sea (e.g documents, maps, high-resolution measurements) and combine everything by spatial relationships. In addition, a key component of the Ammunition Cadastre Sea are European research projects e.g. DAIMON or North Sea Wrecks. DAIMON (Decision Aid for Marine Munitions) uses for example artificial intelligence to analyze complex situations and provides recommendations for actions.\n\nNone","original_language":"eng","persons":["Jann

essential in our day to day activities. In developing countries especially in Africa, the road sub-sector accounts for over 80% of the total passenger traffic and 76% of freight leaving a small proportion to water, rail and air transport. For this reason, they need to be in their best condition to increase the productivity of the region.\n\nThe maintenance of the road network in Kenya is handled by five different agencies all coordinated by the government. Ideally, the process involved requires the collection of data for selection and prioritization purposes but this is rarely done due to the associated costs.\n\nThis research aims at providing decision support based on real-time data from different sources including Twitter reports in addition to the data received from the different mandated agencies ensuring a data-driven decision making process.

spatio-temporal OSM-indicators based on the resilience core from Cutter (2016) and exploring the implications for urban planning in the light of revealed thematic tags in the region of Stuttgart.\n“Nobody on this planet is going to be untouched by the impacts of climate change”\nRayendra Pachauri (2014)\n\nThe overarching nature of building resilience across disciplines and its inherent positive mutual understanding due to the association with the immune system, also amongst the non-scientific community, makes it an attractive and increasing popular concept which everybody seems able to grasp its necessity. Hence there is an exponential increase, even limited down to the key words “urban resilience”, in scientific literature over the last decade. Moreover the concept is also taken up by the New Urban Agenda – Habitat III, the SDG goals and also the IPCC. Hand in hand with this development the definitions and operationalizations are innumerable and starting to lay a smoke screen above it. Conjoined, there is a clear lack of validation of resilience measures, including  spatio-temporal aspects but also of the single component of it (Bakkensen 2017). Moreover, traditional data sources like census or governmental data miss out on certain important facets making empirical validation impossible and lack the spatio-temporal resolution necessary to cover the characteristics of resilience (Burton 2014). Hence, this experimental study explores and develops new spatial indicators through machine learning methods derived from OpenStreetMap data to replicate conventional core indicators. In order to cover all spatial attributes indicators for points, lines and areas will be deduced and separately as well as in a combined analysis investigated by means of supervised and unsupervised algorithms. The outcome is expected to uncover hidden spatial relations and patterns of urban resilience. Moreover, Burton (2014) stresses the need for new data sources to better understand the multifaceted phenomena of urban resilience. Therefore this study is contributing in developing robust and reliable socio-economic indicators contributing to this challenge to clear up the smoke.\n\nNone","original_language":"eng","persons":["Jörn Birkmann","Daniel Feldmeyer","Holger

But it is important to work under a conceptual framework that considers communities as socio-ecosystems, especially with climate change. In Colombia, floods have always been a serious threat for its population, and many coastal communities could be in risk. To face these hazards, mangrove forests are fundamental elements for the resilience of coastal livelihoods and the entire coastal zones. Then the COASTMAP URABÁ project that is being carried out since 2017 in the Urabá gulf in Colombia and that so far has created free access maps of two coastal communities using the mapping methodology created by the HOT team, has allowed the development of a Flood Vulnerability Index for coastal social-ecosystems (FVIc) that could be used in all the coastal communities of the country.\n\nNone","original_language":"eng","persons":["María Fernanda Peña Valencia"],"tags":["bucharest","431","2019","General"],"view_count":29,"promoted":false,"date":"2019-08-30T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2024-05-18T20:00:03.218+02:00","length":1175,"duration":1175,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/431-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/431-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/431-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/431-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-431-flood-vulnerability-index-for-coastal-communities-linked-to-mangrove-forests-based-on-the-coastmap-urab-project-in-colombia","url":"https://api.media.ccc.de/public/events/c66f5d1f-aaa2-542e-a714-87dca2a3ad98","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7491,"event_guid":"7ce19c2c-7bc3-5ba7-b454-b383a7c58c6c","weight":1},{"event_id":7498,"event_guid":"b197164d-0898-54b9-9348-e8d76b0efb91","weight":1},{"event_id":7517,"event_guid":"ef1a3ce2-61bf-53e1-8f97-acb738c219f9","weight":1},{"event_id":7533,"event_guid":"bff8e480-f2e6-5fb7-a945-fed5e6b06f77","weight":1},{"event_id":7575,"event_guid":"bcca12c5-309f-588b-a67e-c5f1fc31f998","weight":1},{"event_id":7579,"event_guid":"0112454d-62b2-5132-8971-73c7fdb972d0","weight":1},{"event_id":7589,"event_guid":"42fe787e-4472-5c3d-a5d8-142940a0f281","weight":1},{"event_id":7612,"event_guid":"20bb8f65-038d-5e73-bba1-186f5b40f548","weight":1},{"event_id":7636,"event_guid":"de42794d-e607-5d76-9b1e-3b5e52bd6c68","weight":1},{"event_id":7645,"event_guid":"efd996c1-5096-5b23-bf42-3dd6818dc072","weight":1},{"event_id":7678,"event_guid":"c9058144-0344-5cdd-9e8d-228d9a6443f3","weight":1},{"event_id":7696,"event_guid":"cf0c6d43-7a50-5d88-b6dd-db5aa818aff8","weight":1},{"event_id":7729,"event_guid":"9d030aa8-27aa-509b-913f-ee9eff97257b","weight":1},{"event_id":7748,"event_guid":"753ef9d6-c39e-5cdb-88c5-1ebe4760f70a","weight":1},{"event_id":7754,"event_guid":"a413689b-2102-5eec-93ef-bae111230fd3","weight":1},{"event_id":7758,"event_guid":"d7541c86-83fd-55c3-8843-f64e30b8aa55","weight":1}]},{"guid":"13ee3371-c9cb-5781-ad63-7e8477ad6b00","title":"USE OF OPEN-SOURCE SOFTWARE  IN TRAINING MODULE AS A PART OF PANAFGEO PROJECT","subtitle":null,"slug":"bucharest-312-use-of-open-source-software-in-training-module-as-a-part-of-panafgeo-project","link":"https://talks.2019.foss4g.org/bucharest/talk/VVYEDW/","description":"PanAfGeo (Pan-African Support to the EuroGeoSurveys-Organisation of African Geological Surveys (EGS-OAGS) Partnership) is an ongoing project which supports the training of geoscientific staff from African Geological Surveys through the development of an innovative training programme. \nIt aims to increase African-owned geological knowledge and skills, with the emphasis on cost-efficiency by using open source software. \nAmong all trainings planned in the project under the umbrella of Geoscience Information Management work package contemporary methods and techniques were introduced in three modules:  Spatial Data Infrastructure, Using GIS and spatial databases and 3D Geological Modelling.\nGeological Survey of Slovenia with assistance of the African Minerals \u0026 Geosciences Centre (Tanzania, November 2017) and Geological Survey of Botswana (Botswana, May 2019) organized two trainings on Spatial Data Infrastructure (SDI), focused on how to make geological data interoperable and available to a wide range of stakeholders and end users.

Ubigu Ltd, Tietotakomo, Gispo Ltd,  Finnish Environment Institute and City of Tampere in Finland have crafted an open source climate tool during spring 2019. It was created using QGIS, PostGIS, GeoServer and Oskari map service for detecting what areas have more CO2 emissions than others taking into account also carbon sinks. The climate tool is used to do better land use planning to achieve CO2 neutral city.\n\nThe base of the calculation comes from 250*250 m urban zone grid by Finnish Environment Institute where we have information about workplaces, demography and buildings. The tool utilizes also different climate parameters and combines the information to the grids. The user interface was created with QGIS and where analysis was driven with algorithms stored to PostGIS database. The tool also provides CO2 visualisation of the analysis results via GeoServer and in the end Oskari map service. In this presentation we will go through the background and demonstrate the use of the tool.\n\nNone","original_language":"eng","persons":["Sanna Jokela"],"tags":["bucharest","175","2019","General"],"view_count":193,"promoted":false,"date":"2019-08-28T00:00:00.000+02:00","release_date":"2019-08-29T02:00:00.000+02:00","updated_at":"2025-06-17T13:00:06.759+02:00","length":1346,"duration":1346,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/175-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/175-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/175-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/175-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-175-calculating-co2-emissions-for-urban-land-use-planning-with-foss4g-tools","url":"https://api.media.ccc.de/public/events/c6a74a91-9d1a-55b9-ae43-118e9abb2617","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7371,"event_guid":"074a5ea0-fd00-4529-912c-c986a8856f6b","weight":2},{"event_id":7464,"event_guid":"a5a5b7b3-060a-582a-b1b2-f626a681e79b","weight":2},{"event_id":7472,"event_guid":"d021f555-141a-58f6-a21b-a787b1c84188","weight":2},{"event_id":7478,"event_guid":"ae1cdec5-93fe-5638-a167-faa6e81cf9c6","weight":3},{"event_id":7482,"event_guid":"89395e98-1ee1-5eee-ae26-cbaa54630177","weight":1},{"event_id":7483,"event_guid":"54f0806e-4257-53c6-a558-e336ee584bb5","weight":2},{"event_id":7484,"event_guid":"b4d6c8c6-688b-5273-aa8f-a2044128ac13","weight":1},{"event_id":7487,"event_guid":"6f1b8b15-b44a-592c-b3e9-96bd9e0fbce3","weight":3},{"event_id":7490,"event_guid":"8b42d166-f7a0-5cc0-a66d-5717fc99b6d0","weight":1},{"event_id":7492,"event_guid":"f65e1c2f-8bde-5c89-a128-e113b0b9a3f6","weight":1},{"event_id":7495,"event_guid":"bffc8bd9-0df8-5543-8c24-254c05092bbd","weight":4},{"event_id":7501,"event_guid":"a4aa4222-f2ca-5e0c-94f6-4c7a3595d1a2","weight":1},{"event_id":7505,"event_guid":"5ac07c14-e2f1-5cba-a86f-047443848af5","weight":2},{"event_id":7514,"event_guid":"0d63b0b4-259d-5114-8c8f-18604b514f7d","weight":2},{"event_id":7525,"event_guid":"9cb9910c-3b3f-5cec-830b-24e93de3edc9","weight":2},{"event_id":7530,"event_guid":"27739ac4-67df-54da-a0f4-633bc7a9ac61","weight":1},{"event_id":7546,"event_guid":"c2504e4b-02f0-5347-92b9-bcd1d86d7df4","weight":1},{"event_id":7549,"event_guid":"7b9c8b02-7d33-5172-b0ea-841a26d389b0","weight":1},{"event_id":7551,"event_guid":"390f46cd-b632-5bbd-b24c-463606723436","weight":3},{"event_id":7556,"event_guid":"c9b9934c-1cec-518c-ab2f-6a70ee5622f0","weight":2},{"event_id":7565,"event_guid":"3bf3bca5-f60f-5af0-b8a8-8a0a229b234b","weight":1},{"event_id":7575,"event_guid":"bcca12c5-309f-588b-a67e-c5f1fc31f998","weight":3},{"event_id":7579,"event_guid":"0112454d-62b2-5132-8971-73c7fdb972d0","weight":4},{"event_id":7594,"event_guid":"9f3b41cc-dc93-55d8-a318-7b7740109b71","weight":3},{"event_id":7607,"event_guid":"d0794cae-d707-584c-8879-6c438a603486","weight":2},{"event_id":7608,"event_guid":"13e2ef4d-8375-580b-a797-c54a85faa0aa","weight":2},{"event_id":7623,"event_guid":"d7305220-5dac-5581-bf1b-14e735c39756","weight":2},{"event_id":7662,"event_guid":"a8fbf537-cbe1-5f17-aa73-97d64132f660","weight":3},{"event_id":7672,"event_guid":"1c58bd3e-15f6-51a3-af44-9d6a75f31556","weight":2},{"event_id":7682,"event_guid":"3da56fe5-5d22-565b-849f-591265220120","weight":2},{"event_id":7740,"event_guid":"503efde4-1e72-51f5-b508-4ca91a364086","weight":1},{"event_id":7748,"event_guid":"753ef9d6-c39e-5cdb-88c5-1ebe4760f70a","weight":1},{"event_id":7753,"event_guid":"5f917971-56e2-5166-a686-07e384a9228d","weight":2},{"event_id":7756,"event_guid":"c4299de5-e39e-576d-93bb-7ae47fee42af","weight":3},{"event_id":7759,"event_guid":"2dbbceca-916a-5619-8d57-6bd9f57db57a","weight":2}]},{"guid":"e303b05d-9930-593f-8184-9233c04f6ec7","title":"How to host and access STAC Imagery using Google's gRPC Remote Procedure Call framework and Protobuf messages","subtitle":null,"slug":"bucharest-426-how-to-host-and-access-stac-imagery-using-google-s-grpc-remote-procedure-call-framework-and-protobuf-messages","link":"https://talks.2019.foss4g.org/bucharest/talk/7NBS9M/","description":"At Swiftera we've built a Spatio Temporal Asset Catalog (STAC) service using the gRPC framework and protobuf messages (instead of the OpenAPI framework and JSON messages) . The Remote Procedure Call framework, gRPC, and the protobuf message format are what Google uses internally for it's micro-services (10s of billions of messages a second). Since Google open sourced gRPC 4 years ago, it has been widely adopted by companies moving massive amounts of data (Netflix,  Salesforce, Spotify and others). But it isn't only about performance, it's also an suprisingly easy framework to get up and running. At FOSS4GNA we open sourced our NAIP metadata service and the IDL defining the services and messages. By Bucharest we plan to have added Landsat and Sentinel to our public gRPC service. We want to share more about what it's like to work with gRPC and the ease of development for hosting your own gRPC services.\n\nNone","original_language":"eng","persons":["David

You can access your geospatial data for example geopackage or OGC WFS via FDW. That is easy and great fun. \n\nSome of the wrappers support only read others support read/write access.\n\nThe presentation will give an overview on the possibilities of Foreign Data Wrappers and

community is much more than OS Software. The community, while small globally, has had, and continues to have an outsized impact on science using geospatial data. This impact starts with Open Ideas: the community fosters the free-flow exchange of ideas that lead to Open Standards for interoperability, Open Data for democratizing data access, and Open Source Software for the use and analysis of data.\n\nScience fields wishing to leverage remote sensing data has historically suffered from several challenges. Archives of remote sensing data can be large, and finding just the desired pieces of data can be time consuming, as every dataset is accessed in different ways. The data then often requires pre-processing and reformatting: reprojection, clipping, assembling time series, or even some more complex operations. Lastly, processing and analyzing these large datasets can take massive computing resources, making large scale studies difficult, if not impossible. The impact of all this on Open Science (the movement to make science more accessible on all levels) is clear - complex custom-made tools required for each dataset does not support making science more accessible.\n\nNow, the culmination of several advances in Open Standards, Open Data, and Open Source, along with cloud computing, are helping realize Open Science. And FOSS4G has been here all along, where many of these advances started as Open Ideas.\n\nNone","original_language":"eng","persons":["Matthew Hanson"],"tags":["bucharest","471","2019","Keynote"],"view_count":135,"promoted":false,"date":"2019-08-30T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2023-09-08T11:45:04.823+02:00","length":1554,"duration":1554,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/471-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/471-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/471-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/471-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-471-how-open-is-revolutionizing-science","url":"https://api.media.ccc.de/public/events/a413689b-2102-5eec-93ef-bae111230fd3","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":6060,"event_guid":"d6d52c1e-1507-4bd6-8cc7-57c0080e9a2d","weight":1},{"event_id":7465,"event_guid":"d2b2bdd0-36fa-5ae1-aba0-a38960010e3b","weight":3},{"event_id":7466,"event_guid":"98c0417b-cdfd-57b3-9411-14f9f465f5b9","weight":2},{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":3},{"event_id":7472,"event_guid":"d021f555-141a-58f6-a21b-a787b1c84188","weight":2},{"event_id":7484,"event_guid":"b4d6c8c6-688b-5273-aa8f-a2044128ac13","weight":3},{"event_id":7487,"event_guid":"6f1b8b15-b44a-592c-b3e9-96bd9e0fbce3","weight":3},{"event_id":7498,"event_guid":"b197164d-0898-54b9-9348-e8d76b0efb91","weight":1},{"event_id":7504,"event_guid":"c54aa667-78de-55fb-85e7-60f2eaffd2a4","weight":1},{"event_id":7518,"event_guid":"8773035b-d16c-5cf3-902d-43abc7e5dab7","weight":2},{"event_id":7573,"event_guid":"347ab764-8ae3-58fe-87a0-18dca9880c63","weight":3},{"event_id":7579,"event_guid":"0112454d-62b2-5132-8971-73c7fdb972d0","weight":1},{"event_id":7590,"event_guid":"0bdb57e7-edb8-50e8-a60e-4ec5480e14b9","weight":2},{"event_id":7594,"event_guid":"9f3b41cc-dc93-55d8-a318-7b7740109b71","weight":2},{"event_id":7607,"event_guid":"d0794cae-d707-584c-8879-6c438a603486","weight":2},{"event_id":7612,"event_guid":"20bb8f65-038d-5e73-bba1-186f5b40f548","weight":2},{"event_id":7694,"event_guid":"05466dda-8c63-57a3-a1ff-ebeff2abaa92","weight":2},{"event_id":7729,"event_guid":"9d030aa8-27aa-509b-913f-ee9eff97257b","weight":3},{"event_id":7745,"event_guid":"c66f5d1f-aaa2-542e-a714-87dca2a3ad98","weight":1},{"event_id":7753,"event_guid":"5f917971-56e2-5166-a686-07e384a9228d","weight":3},{"event_id":7755,"event_guid":"f651ccfa-c224-5cfa-b76b-f7b44b4ef563","weight":3},{"event_id":7756,"event_guid":"c4299de5-e39e-576d-93bb-7ae47fee42af","weight":8},{"event_id":7757,"event_guid":"08e7e90e-7da4-524d-8875-b38d23b6c1cf","weight":5}]},{"guid":"8b42d166-f7a0-5cc0-a66d-5717fc99b6d0","title":"Oskari technical developments","subtitle":null,"slug":"bucharest-238-oskari-technical-developments","link":"https://talks.2019.foss4g.org/bucharest/talk/QYFKQG/","description":"[Oskari](http://oskari.org) ([GitHub](https://github.com/oskariorg)) is a open source product for creating geoportals built on top of distributed spatial data infrastructure (like INSPIRE) and is currently incubating for becoming an OSGeo project.

In the case of geospatial data, a postprocessing step is often necessary for displaying the results in web applications and GIS tools.\n\nA concrete illustration of our results will be provided through a light Flask application designed for demonstration purpose.\n\nNone","original_language":"eng","persons":["Raphaël Delhome"],"tags":["bucharest","196","2019","General"],"view_count":127,"promoted":false,"date":"2019-08-29T00:00:00.000+02:00","release_date":"2019-08-29T02:00:00.000+02:00","updated_at":"2025-06-23T12:45:02.779+02:00","length":1457,"duration":1457,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/196-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/196-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/196-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/196-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-196-geospatial-data-processing-for-image-automatic-analysis","url":"https://api.media.ccc.de/public/events/5ac07c14-e2f1-5cba-a86f-047443848af5","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7465,"event_guid":"d2b2bdd0-36fa-5ae1-aba0-a38960010e3b","weight":11},{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":7},{"event_id":7469,"event_guid":"c0174aef-c7a6-5d21-8dfe-e592c5a4eff3","weight":4},{"event_id":7473,"event_guid":"feda735f-5467-56f0-9ddf-55cefdf60199","weight":1},{"event_id":7475,"event_guid":"49a7c19c-a42e-5058-afe1-7577dd2736c9","weight":4},{"event_id":7478,"event_guid":"ae1cdec5-93fe-5638-a167-faa6e81cf9c6","weight":1},{"event_id":7481,"event_guid":"c6a74a91-9d1a-55b9-ae43-118e9abb2617","weight":1},{"event_id":7484,"event_guid":"b4d6c8c6-688b-5273-aa8f-a2044128ac13","weight":6},{"event_id":7487,"event_guid":"6f1b8b15-b44a-592c-b3e9-96bd9e0fbce3","weight":1},{"event_id":7492,"event_guid":"f65e1c2f-8bde-5c89-a128-e113b0b9a3f6","weight":4},{"event_id":7495,"event_guid":"bffc8bd9-0df8-5543-8c24-254c05092bbd","weight":4},{"event_id":7504,"event_guid":"c54aa667-78de-55fb-85e7-60f2eaffd2a4","weight":10},{"event_id":7515,"event_guid":"b744af16-2f4c-5151-bca1-91449f719965","weight":1},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":5},{"event_id":7526,"event_guid":"fd5614a8-535f-5069-8f69-3a9983d37830","weight":1},{"event_id":7533,"event_guid":"bff8e480-f2e6-5fb7-a945-fed5e6b06f77","weight":3},{"event_id":7536,"event_guid":"9f921eab-53c5-5ce7-9489-45a586162248","weight":1},{"event_id":7545,"event_guid":"726938bf-af52-5c0e-9198-0053eba64726","weight":5},{"event_id":7548,"event_guid":"8ca1b4b6-ee0c-5102-ab95-a978cd3b4d8c","weight":6},{"event_id":7561,"event_guid":"1125685c-9fdc-5572-89c0-8bc80c7df3e0","weight":4},{"event_id":7568,"event_guid":"7a848633-35e2-5b06-962e-c9cb71cf9762","weight":4},{"event_id":7584,"event_guid":"41e880ab-ca8a-5a40-aeeb-4b75fb3a94d3","weight":5},{"event_id":7594,"event_guid":"9f3b41cc-dc93-55d8-a318-7b7740109b71","weight":4},{"event_id":7607,"event_guid":"d0794cae-d707-584c-8879-6c438a603486","weight":6},{"event_id":7623,"event_guid":"d7305220-5dac-5581-bf1b-14e735c39756","weight":6},{"event_id":7652,"event_guid":"e04c27d0-8ff8-5bf4-b932-34db4e4fdf5b","weight":5},{"event_id":7672,"event_guid":"1c58bd3e-15f6-51a3-af44-9d6a75f31556","weight":3},{"event_id":7725,"event_guid":"63a63204-d0dd-57d5-aae3-d766a3be9d23","weight":3},{"event_id":7758,"event_guid":"d7541c86-83fd-55c3-8843-f64e30b8aa55","weight":2}]},{"guid":"6c1f2dfd-1e20-5232-9dc0-f66bdc178f1f","title":"State of deegree 2019","subtitle":null,"slug":"bucharest-128-state-of-deegree-2019","link":"https://talks.2019.foss4g.org/bucharest/talk/Y399BF/","description":"State of deegree 2019 provides an update on our community and reviews the latest and noteworthy features of [deegree webservices](https://www.deegree.org/).\nInitiated in 2002 the OSGeo project deegree has developed over the last 17 years to an important building block for Spatial Data Infrastructures (SDI). As the implementation of the INSPIRE Directive is fully underway it requires stable and mature software solutions based on OGC standards such as GML, WFS and WMS. One of the goals of the deegree project is to provide implementation of those standards. \nIn this talk, after a short overview of the current status, we will focus on the recent improvements available in deegree such as GeoJSON support and our roadmap for Java 11 and OpenJDK. \n\nFinally, we will explore potential future directions for the project and show what future developments are currently planned such as the support for the OGC WFS 3.0 standard.\n\nNone","original_language":"eng","persons":["Torsten Friebe","Dirk Stenger","Stephan

It will open a discussion and hopefully a brainstorm on the way forward.\n\nNone","original_language":"eng","persons":["Lars Agerskov Christensen"],"tags":["bucharest","231","2019","General"],"view_count":50,"promoted":false,"date":"2019-08-28T00:00:00.000+02:00","release_date":"2019-08-29T02:00:00.000+02:00","updated_at":"2025-01-29T13:45:11.679+01:00","length":1278,"duration":1278,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/231-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/231-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/231-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/231-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-231-data-is-useless-","url":"https://api.media.ccc.de/public/events/bff8e480-f2e6-5fb7-a945-fed5e6b06f77","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7322,"event_guid":"37eebf57-a64d-4cc8-8ee1-226810ac834a","weight":1},{"event_id":7357,"event_guid":"38775ee6-c151-4cc6-974c-4d121f95b159","weight":1},{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":2},{"event_id":7475,"event_guid":"49a7c19c-a42e-5058-afe1-7577dd2736c9","weight":2},{"event_id":7478,"event_guid":"ae1cdec5-93fe-5638-a167-faa6e81cf9c6","weight":3},{"event_id":7482,"event_guid":"89395e98-1ee1-5eee-ae26-cbaa54630177","weight":3},{"event_id":7492,"event_guid":"f65e1c2f-8bde-5c89-a128-e113b0b9a3f6","weight":1},{"event_id":7501,"event_guid":"a4aa4222-f2ca-5e0c-94f6-4c7a3595d1a2","weight":2},{"event_id":7505,"event_guid":"5ac07c14-e2f1-5cba-a86f-047443848af5","weight":3},{"event_id":7517,"event_guid":"ef1a3ce2-61bf-53e1-8f97-acb738c219f9","weight":2},{"event_id":7518,"event_guid":"8773035b-d16c-5cf3-902d-43abc7e5dab7","weight":1},{"event_id":7534,"event_guid":"3fc26cc4-962e-5f27-a92b-c01e86d12100","weight":2},{"event_id":7555,"event_guid":"a641fc9b-2eb6-5580-8acc-4236e227de4e","weight":1},{"event_id":7561,"event_guid":"1125685c-9fdc-5572-89c0-8bc80c7df3e0","weight":1},{"event_id":7573,"event_guid":"347ab764-8ae3-58fe-87a0-18dca9880c63","weight":1},{"event_id":7579,"event_guid":"0112454d-62b2-5132-8971-73c7fdb972d0","weight":3},{"event_id":7582,"event_guid":"95c65e38-a93e-5306-a9c6-b1cdc197bb58","weight":3},{"event_id":7593,"event_guid":"6a8c04d0-d372-5f16-87a2-96f537854ebc","weight":2},{"event_id":7594,"event_guid":"9f3b41cc-dc93-55d8-a318-7b7740109b71","weight":3},{"event_id":7602,"event_guid":"7e1569ea-459c-5b0f-9aa3-59393152500f","weight":2},{"event_id":7607,"event_guid":"d0794cae-d707-584c-8879-6c438a603486","weight":2},{"event_id":7614,"event_guid":"7347a409-8f11-53a7-b855-39fcf0d8c2ae","weight":2},{"event_id":7616,"event_guid":"23bc1246-3fcb-5ce4-ac80-f8c176a25d97","weight":1},{"event_id":7618,"event_guid":"6ed3f0f2-a47f-5229-b734-0c911d11f597","weight":1},{"event_id":7632,"event_guid":"99a39bf7-5c95-5bc3-947a-55e28aa0a042","weight":2},{"event_id":7633,"event_guid":"a8aaa8da-f9ee-53ef-958c-ff6f326b3f81","weight":2},{"event_id":7652,"event_guid":"e04c27d0-8ff8-5bf4-b932-34db4e4fdf5b","weight":2},{"event_id":7661,"event_guid":"afb75703-96a4-5546-b1fa-493154ef35ae","weight":1},{"event_id":7666,"event_guid":"5b35bf19-e251-5dea-96f1-49e2f0f88d09","weight":1},{"event_id":7667,"event_guid":"4bc8bbe5-cb04-5a2b-b441-a696be055948","weight":3},{"event_id":7674,"event_guid":"ac484924-85f6-5195-bf5b-9f689f24ef57","weight":3},{"event_id":7691,"event_guid":"51a27fc2-ea89-5b31-8a60-fed8cdc9ef91","weight":2},{"event_id":7694,"event_guid":"05466dda-8c63-57a3-a1ff-ebeff2abaa92","weight":1},{"event_id":7695,"event_guid":"5df0ebe1-cfe2-54c4-a0c8-40e35a6de826","weight":3},{"event_id":7709,"event_guid":"936a0a3d-27d2-5bb7-a59a-336837047e72","weight":2},{"event_id":7710,"event_guid":"9bce8e1a-0dc8-5c82-977c-23dccd115e89","weight":2},{"event_id":7729,"event_guid":"9d030aa8-27aa-509b-913f-ee9eff97257b","weight":2},{"event_id":7756,"event_guid":"c4299de5-e39e-576d-93bb-7ae47fee42af","weight":3},{"event_id":7758,"event_guid":"d7541c86-83fd-55c3-8843-f64e30b8aa55","weight":2}]},{"guid":"bb1806af-1579-5ee7-916e-099ef1bb74f1","title":"MapMint: The service-oriented platform","subtitle":null,"slug":"bucharest-343-mapmint-the-service-oriented-platform","link":"https://talks.2019.foss4g.org/bucharest/talk/E8UVGW/","description":"MapMint is a comprehensive task manager for publishing web mapping applications. It is a robust\nopen source geospatial platform allowing the user to organize, edit, process and publish spatial data\nto the Internet. MapMint includes a complete administration tool for MapServer and simple user\ninterfaces to create mapfiles visually.\nMapMint is based on the extensive use of OGC standards and automates WMS, WFS, WMT-S, and\nWPS. Most of the MapMint core functions are run through WPS requests which are calling general or\ngeospatial web services: vector and raster operations, mapfiles creation, spatial analysis and queries\nand much more. MapMint server-side is built on top of ZOO-Project, MapServer and GDAL and its\nnumerous WPS services are written in C, Python and JavaScript. MapMint client-side is based on\nOpenLayers and Jquery and provides user-friendly tools to create, publish and view maps.\nMapMint architecture and main features will be introduced in this presentation, and its modules\n(dashboard, distiller, manager, and publisher) will be described with an emphasis on the OGC standards and\nOSGeo software they are using.

For long time, these HPC resources were used mainly for chemistry, (micro)-biology, physics and material sciences. In recent years, we have installed a lot of GIS software and added open licensed GIS data to the HPC environment. We have installed to a Taito supercomputer: FORCE, GDAL, GRASS GIS, PDAL, QGIS, SAGA GIS, SNAP, Taudem, Zonation, and Python and R with tens of spatial packages. The amount of data is currently about 10 Tb, including almost 300 different datsets mainly from Finnish governmental organizations. \n\nBesides supercluster, we also provide OpenStack-based cloud environment cPouta and OpenShift-based container cloud environment Rahti, for users who want to set up their web service or database. An important use case for these services has also been setting up training environment for university courses.\n\nThe amount of users has increased with fast speed, being around 200 at the

Validator is the tool adopted by EU Member States to validate the resources of their Spatial Data Infrastructures. It is an implementation of the ETF, an open source testing framework based on ISO and OGC standards, which performs tests organized into Executable Test Suites (ETS) using SoapUI, BaseX and TEAM Engine. The ETF can be used via either a web application or a REST API; a Docker container is also available for quick deployment. The INSPIRE Reference Validator, recently deployed on the cloud, offers many open source ETS to test data sets, metadata, View Services (WMS, WMTS), Download Services (Atom, WFS, WCS, SOS) and Discovery Services (CSW) against the interoperability requirements set by the INSPIRE Technical Guidance documents. Starting from the context of INSPIRE Action 2017.4 on Validation and conformity testing, the talk will present the latest developments of the ETS and ETF (including the governance of the software project) and describe the future plans.\n\nNone","original_language":"eng","persons":["Belén Sáez","Iñaki Díaz de Cerio Paniagua","Carlos Palma","Enrique Soriano","Jon Herrmann","Clemens Portele","Michael Lutz","Marco Minghini"],"tags":["bucharest","435","2019","General"],"view_count":48,"promoted":false,"date":"2019-08-28T00:00:00.000+02:00","release_date":"2019-08-29T02:00:00.000+02:00","updated_at":"2023-11-15T11:30:02.569+01:00","length":1565,"duration":1565,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/435-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/435-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/435-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/435-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-435-inspire-reference-validator-status-and-next-steps","url":"https://api.media.ccc.de/public/events/ceaf6b0d-7e1a-5262-a7ae-61533de03fde","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7466,"event_guid":"98c0417b-cdfd-57b3-9411-14f9f465f5b9","weight":1},{"event_id":7471,"event_guid":"3c2d5b68-ca8e-5c4e-9110-59ad868cfc70","weight":1},{"event_id":7473,"event_guid":"feda735f-5467-56f0-9ddf-55cefdf60199","weight":2},{"event_id":7478,"event_guid":"ae1cdec5-93fe-5638-a167-faa6e81cf9c6","weight":4},{"event_id":7482,"event_guid":"89395e98-1ee1-5eee-ae26-cbaa54630177","weight":2},{"event_id":7487,"event_guid":"6f1b8b15-b44a-592c-b3e9-96bd9e0fbce3","weight":2},{"event_id":7495,"event_guid":"bffc8bd9-0df8-5543-8c24-254c05092bbd","weight":2},{"event_id":7497,"event_guid":"ee2c0473-7931-5239-85f0-0385fb68054e","weight":2},{"event_id":7499,"event_guid":"de560d64-70a3-518c-b12d-5b639a1c7b97","weight":2},{"event_id":7510,"event_guid":"ab6c65d7-f9df-563f-b9bb-e36c128e9ab4","weight":1},{"event_id":7511,"event_guid":"12a2750d-c71a-5b02-b16b-a66cea7b33ac","weight":3},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":2},{"event_id":7524,"event_guid":"f58c39cb-2250-51b5-8902-d52f713c934b","weight":2},{"event_id":7527,"event_guid":"b05efa77-03a4-5ff9-a037-06d5aa2a1b6d","weight":1},{"event_id":7530,"event_guid":"27739ac4-67df-54da-a0f4-633bc7a9ac61","weight":2},{"event_id":7532,"event_guid":"e7956d52-af40-563e-ae3e-1df491ad6591","weight":4},{"event_id":7551,"event_guid":"390f46cd-b632-5bbd-b24c-463606723436","weight":3},{"event_id":7552,"event_guid":"4c2f4b81-1316-502d-870c-dc39567b782e","weight":1},{"event_id":7578,"event_guid":"d5d6bac8-cb8a-504a-9a3f-ced5c377e1bd","weight":1},{"event_id":7629,"event_guid":"43e2163d-d0f7-5b45-945b-25dd8c57118b","weight":1},{"event_id":7647,"event_guid":"39de1ec8-9848-55e3-a2c6-99d40d5f2d97","weight":1},{"event_id":7659,"event_guid":"81f32156-c1c3-5ee8-8fec-e5800350f677","weight":2},{"event_id":7675,"event_guid":"9e54b705-cdd9-5485-8bec-d392c97aee70","weight":3},{"event_id":7703,"event_guid":"38fb4b40-3935-5dbc-b54a-551830e317d8","weight":1},{"event_id":7736,"event_guid":"61205921-df6b-5dff-902b-9d757f719602","weight":1}]},{"guid":"d7305220-5dac-5581-bf1b-14e735c39756","title":"Deforestation Monitoring using Change Detection","subtitle":null,"slug":"bucharest-114-deforestation-monitoring-using-change-detection","link":"https://talks.2019.foss4g.org/bucharest/talk/TMEUWB/","description":"In 2018, Ecometrica Ltd. was tasked with identifying potential deforestation over 7000 sites spread across South America over a one year period.

With these improved products and their 3D characteristics, more can be derived from their analysis including the detection and location of important changes over time. The analysis between two temporally different DEMs, digital terrain models (DTMs) or digital simulations models (DSMs) can indicate important factors such as erosion, structural damage, or deforestation. The talk will discuss a project that focuses on the suitability of creating a plugin for QGIS to automate the process of performing 3D change detection with these data types. It is expected that the need for an intuitive and automated process for this type of analysis will only increase with the feasibility of DEM generation and collection with new software and UAS popularity.\n\nNone","original_language":"eng","persons":["Jordan Bates","Muhammad Hasan Mustafa","Tanmoy Chakraborty"],"tags":["bucharest","165","2019","General"],"view_count":166,"promoted":false,"date":"2019-08-29T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2025-04-11T14:00:06.820+02:00","length":1353,"duration":1353,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/165-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/165-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/165-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/165-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-165-three-d-change-detection-a-qgis-plugin-with-python-3","url":"https://api.media.ccc.de/public/events/95c65e38-a93e-5306-a9c6-b1cdc197bb58","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7465,"event_guid":"d2b2bdd0-36fa-5ae1-aba0-a38960010e3b","weight":3},{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":3},{"event_id":7518,"event_guid":"8773035b-d16c-5cf3-902d-43abc7e5dab7","weight":3},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":6},{"event_id":7535,"event_guid":"6f455f9f-a9a4-502e-8e73-b0208dbe8427","weight":4},{"event_id":7547,"event_guid":"a31e875c-a407-5233-a81b-d682a44e33b7","weight":2},{"event_id":7551,"event_guid":"390f46cd-b632-5bbd-b24c-463606723436","weight":1},{"event_id":7565,"event_guid":"3bf3bca5-f60f-5af0-b8a8-8a0a229b234b","weight":1},{"event_id":7571,"event_guid":"ff3f8976-451e-5f00-bc69-fb2dea80b3bb","weight":1},{"event_id":7606,"event_guid":"c0ebaf1b-03d8-53f4-81d1-b5b306e93c60","weight":4},{"event_id":7607,"event_guid":"d0794cae-d707-584c-8879-6c438a603486","weight":3},{"event_id":7624,"event_guid":"69079f64-448d-55b5-9cb3-7089547c370d","weight":4},{"event_id":7648,"event_guid":"82181807-6c4a-560f-a34d-116d440a540b","weight":3},{"event_id":7652,"event_guid":"e04c27d0-8ff8-5bf4-b932-34db4e4fdf5b","weight":4},{"event_id":7661,"event_guid":"afb75703-96a4-5546-b1fa-493154ef35ae","weight":2},{"event_id":7662,"event_guid":"a8fbf537-cbe1-5f17-aa73-97d64132f660","weight":1},{"event_id":7663,"event_guid":"1b265f5f-a622-52e0-a2a4-88105aa09aba","weight":5},{"event_id":7669,"event_guid":"7627a093-69e4-5c72-b8b5-0f05c27ce815","weight":5},{"event_id":7674,"event_guid":"ac484924-85f6-5195-bf5b-9f689f24ef57","weight":4},{"event_id":7681,"event_guid":"a1326956-88be-5af4-b747-5cefc95e8232","weight":4},{"event_id":7695,"event_guid":"5df0ebe1-cfe2-54c4-a0c8-40e35a6de826","weight":3},{"event_id":7709,"event_guid":"936a0a3d-27d2-5bb7-a59a-336837047e72","weight":3},{"event_id":7713,"event_guid":"14dfde19-5a7a-59ee-8470-e75266353678","weight":3},{"event_id":7749,"event_guid":"5117b85e-052d-5b96-bcc3-f14e953b887a","weight":3},{"event_id":7756,"event_guid":"c4299de5-e39e-576d-93bb-7ae47fee42af","weight":4}]},{"guid":"603a5649-724a-53d7-ac20-ff7d520696d3","title":"GeoServer feature frenzy","subtitle":null,"slug":"bucharest-170-geoserver-feature-frenzy","link":"https://talks.2019.foss4g.org/bucharest/talk/MZPNAC/","description":"What can you do with this GeoServer thing?

implementation of the OGC Web Processing Service (WPS) standard. It provides users with a relatively seamless environment where to code geo-spatial functions and models that are readily exposed to the Internet through the WWW.\n\nInitially started in 2006, the current 4.x version takes advantage of the state-of-the-art Python infrastructure in order to provide new and useful features. The current version implements the WPS 1.0 standard entirely. The WPS 2.0.0 and it's features is currently on-hold status.\n\nPyWPS offers a straightforward WPS development framework with the increasingly popular Python language. Python offers access to a vast array of code libraries that can be easily used in the processes, in particular those for geo-spatial data manipulation, e.g. GRASS, GDAL/OGR, Fiona, Shapely, etc., but also to statistics packages (e.g. rpy2 for R statistics) and data analysis tools (e.g. pandas). PyWPS offers storage mechanisms for process inputs and outputs and spawns processes to the background for asynchronous execution requests.\n\nTalk will present features of the last 12 months of development and outline the roadmap for next versions of PyWPS.\n\nNone","original_language":"eng","persons":["Jáchym

always a popular format, with the recent specification of Cloud Optimized GeoTIFFs, the TIFF format has had a renaissance as a cloud enabled storage format. Traditional processing software like GDAL took advantage of that, but is not available for browsers and had to rely on server-side processing instead.\n\nThe geotiff.js library provides a pure JavaScript implementation of the TIFF format and allows the efficient exploitation of large raster datasets with the full range of values and metadata.\n\nIn this talk, the architecture and techniques used that makes geotiff.js access so efficient will be explained. Additionally recent additional functionalities and developments by growing community will be highlighted.\n\nThe COG-explorer is a demo application to show the capabilities of geotiff.js by allowing to browse TIFF files on top of an OpenLayers map. It allows to access large TIFF files on remote sources and can combine multiple files and rendering mechanisms to generate visually impressive images. It provides advanced and efficient rendering techniques using WebGL and takes full advantage of the layout of cloud optimized GeoTIFFs and the capabilities of geotiff.js.\n\nNone","original_language":"eng","persons":["Fabian Schindler"],"tags":["bucharest","379","2019","General"],"view_count":236,"promoted":false,"date":"2019-08-29T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2025-06-11T23:30:03.929+02:00","length":1422,"duration":1422,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/379-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/379-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/379-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/379-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-379-discover-huge-raster-files-in-the-browser-with-geotiff-js","url":"https://api.media.ccc.de/public/events/99a39bf7-5c95-5bc3-947a-55e28aa0a042","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7465,"event_guid":"d2b2bdd0-36fa-5ae1-aba0-a38960010e3b","weight":4},{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":5},{"event_id":7475,"event_guid":"49a7c19c-a42e-5058-afe1-7577dd2736c9","weight":4},{"event_id":7484,"event_guid":"b4d6c8c6-688b-5273-aa8f-a2044128ac13","weight":4},{"event_id":7488,"event_guid":"0a3e23aa-d593-58cd-a3a1-7991e3a3a064","weight":3},{"event_id":7492,"event_guid":"f65e1c2f-8bde-5c89-a128-e113b0b9a3f6","weight":3},{"event_id":7501,"event_guid":"a4aa4222-f2ca-5e0c-94f6-4c7a3595d1a2","weight":2},{"event_id":7504,"event_guid":"c54aa667-78de-55fb-85e7-60f2eaffd2a4","weight":2},{"event_id":7505,"event_guid":"5ac07c14-e2f1-5cba-a86f-047443848af5","weight":2},{"event_id":7510,"event_guid":"ab6c65d7-f9df-563f-b9bb-e36c128e9ab4","weight":2},{"event_id":7514,"event_guid":"0d63b0b4-259d-5114-8c8f-18604b514f7d","weight":2},{"event_id":7518,"event_guid":"8773035b-d16c-5cf3-902d-43abc7e5dab7","weight":2},{"event_id":7523,"event_guid":"a95cf31f-07d2-5255-bfa2-6fb38923a15f","weight":2},{"event_id":7524,"event_guid":"f58c39cb-2250-51b5-8902-d52f713c934b","weight":2},{"event_id":7533,"event_guid":"bff8e480-f2e6-5fb7-a945-fed5e6b06f77","weight":2},{"event_id":7534,"event_guid":"3fc26cc4-962e-5f27-a92b-c01e86d12100","weight":4},{"event_id":7550,"event_guid":"53494dbe-b19b-5e77-a2d1-9cb5a6d5447d","weight":2},{"event_id":7552,"event_guid":"4c2f4b81-1316-502d-870c-dc39567b782e","weight":3},{"event_id":7556,"event_guid":"c9b9934c-1cec-518c-ab2f-6a70ee5622f0","weight":2},{"event_id":7561,"event_guid":"1125685c-9fdc-5572-89c0-8bc80c7df3e0","weight":7},{"event_id":7568,"event_guid":"7a848633-35e2-5b06-962e-c9cb71cf9762","weight":2},{"event_id":7573,"event_guid":"347ab764-8ae3-58fe-87a0-18dca9880c63","weight":6},{"event_id":7579,"event_guid":"0112454d-62b2-5132-8971-73c7fdb972d0","weight":2},{"event_id":7607,"event_guid":"d0794cae-d707-584c-8879-6c438a603486","weight":4},{"event_id":7608,"event_guid":"13e2ef4d-8375-580b-a797-c54a85faa0aa","weight":3},{"event_id":7616,"event_guid":"23bc1246-3fcb-5ce4-ac80-f8c176a25d97","weight":2},{"event_id":7659,"event_guid":"81f32156-c1c3-5ee8-8fec-e5800350f677","weight":3},{"event_id":7665,"event_guid":"f1f4f54c-e816-573f-a05d-7973f9f5d48e","weight":2},{"event_id":7721,"event_guid":"9462ccbb-1601-5d12-8756-5e11e3134112","weight":2},{"event_id":7729,"event_guid":"9d030aa8-27aa-509b-913f-ee9eff97257b","weight":2},{"event_id":7742,"event_guid":"3f476837-4583-53e9-8ddf-eb940720a469","weight":6}]},{"guid":"84c94e48-3002-55f3-9d4a-c66f5d2e4198","title":"Building a geo marketing tool with open source geospatial software","subtitle":null,"slug":"bucharest-387-building-a-geo-marketing-tool-with-open-source-geospatial-software","link":"https://talks.2019.foss4g.org/bucharest/talk/Z8X8S7/","description":"# Building a geo marketing tool with open source geospatial software\n\nWe want to tell about the journey we undertook to build a geo marketing platform using open source geospatial software.

movements and traffic in a geographical space, at several scales, are involved (migrations, freight, transportation, etc).\nRequired semiological, aesthetical and design elements offered by currently web-based graphic visualization libraries are also considered.\nIts main goal is to build a simple application combining two pillars of scientific graphical representation: flow data processing and (geo)graphical modalities visualization.\nA state of the art on current issues of flows and movement analysis on the geoweb has been produced through the compilation of around 70 applications in a thematic dashboard, and a 200 respondants survey on flow map usages and needs has been realized.\n\nThis presentation will follow 3 axes: open source applications in the curated corpus, an analysis of

Finally we will give an overview of available STAC catalogs for searching and accessing publicly available datasets (e.g., Landsat-8, Sentinel-1/2, NAIP) using these Open Source tools.\n\nAfter this

service of vector information such as .pbf.\nThis format allows the transmission of large amounts of information to the local browser client.\nThis information, increasingly larger, requires the use of specific rendering libraries such as WebGL.\nThe present work shows a state of the art of the existing WebGL libraries and a real test field on which the data have been tested, showing the results

Opensource project has been an OSGeo project since a decade. It is a catalog application facilitating discovery of resources within any local, regional, national or global SDI. Users can register their spatial datasets, services, maps, sensors in a central catalog. Others can query the catalog to find resources via the website or directly from a GIS application, like GeoNode or QGIS. The catalog records can also be ingested by other catalogs and search engines to facilitate wider discovery.\n\nIn  this presentation the core developers introduce you to recent developments in the community. GeoNetwork adopted a twice-a-year lifecycle, so we’ve released the 3.6 and 3.8 version which had some interesting new features like metadata workflow, history, INSPIRE metadata guidelines 2.0, DOI, user searches, json and json-ld encodings, inline validation, WFS 2 and 19115-3:2018. Currently we’re in a major refactor to migrate the catalog to use ElasticSearch as a base search index for the 4.0 version.\n\nNone","original_language":"eng","persons":["Florent Gravin","Paul van Genuchten","François Prunayre","Antonio Cerciello"],"tags":["bucharest","328","2019","General"],"view_count":109,"promoted":false,"date":"2019-08-29T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2023-09-30T09:30:02.167+02:00","length":1270,"duration":1270,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/328-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/328-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/328-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/328-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-328-geonetwork-opensource-what-s-happening-and-upcoming","url":"https://api.media.ccc.de/public/events/b60859dd-b7b5-5537-acaa-fd695b7cd29a","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7487,"event_guid":"6f1b8b15-b44a-592c-b3e9-96bd9e0fbce3","weight":2},{"event_id":7495,"event_guid":"bffc8bd9-0df8-5543-8c24-254c05092bbd","weight":2},{"event_id":7497,"event_guid":"ee2c0473-7931-5239-85f0-0385fb68054e","weight":1},{"event_id":7501,"event_guid":"a4aa4222-f2ca-5e0c-94f6-4c7a3595d1a2","weight":1},{"event_id":7527,"event_guid":"b05efa77-03a4-5ff9-a037-06d5aa2a1b6d","weight":1},{"event_id":7534,"event_guid":"3fc26cc4-962e-5f27-a92b-c01e86d12100","weight":1},{"event_id":7551,"event_guid":"390f46cd-b632-5bbd-b24c-463606723436","weight":2},{"event_id":7552,"event_guid":"4c2f4b81-1316-502d-870c-dc39567b782e","weight":2},{"event_id":7554,"event_guid":"20bb70f9-e0ab-5d46-9e99-71cd75e04251","weight":2},{"event_id":7555,"event_guid":"a641fc9b-2eb6-5580-8acc-4236e227de4e","weight":1},{"event_id":7567,"event_guid":"49724c62-af53-50b0-87ee-07cee5c4cdfb","weight":10},{"event_id":7592,"event_guid":"31bcb788-988b-56f6-90ba-69ebac85b83d","weight":2},{"event_id":7607,"event_guid":"d0794cae-d707-584c-8879-6c438a603486","weight":1},{"event_id":7623,"event_guid":"d7305220-5dac-5581-bf1b-14e735c39756","weight":1},{"event_id":7628,"event_guid":"437a912d-ff97-5431-a0d3-7d7735f3b14d","weight":1},{"event_id":7667,"event_guid":"4bc8bbe5-cb04-5a2b-b441-a696be055948","weight":1},{"event_id":7687,"event_guid":"a0e3a9de-ed9b-5cc6-8a5b-c9d37476c433","weight":1},{"event_id":7688,"event_guid":"9884da36-043b-5822-920a-f125c93faf74","weight":1},{"event_id":7700,"event_guid":"a45f513c-23e0-512d-a69c-8163e5edf0d8","weight":1},{"event_id":7706,"event_guid":"2931c54a-5a66-5024-87ea-4c283dc0f8f2","weight":1},{"event_id":7707,"event_guid":"8f9b67d8-fd60-522f-9a5b-6f0f81626e5c","weight":1},{"event_id":7721,"event_guid":"9462ccbb-1601-5d12-8756-5e11e3134112","weight":1},{"event_id":7732,"event_guid":"771fc01c-25ee-5202-abbe-0b993a5e7ace","weight":1},{"event_id":7743,"event_guid":"c393e563-c11d-5111-aa92-fc579ac7ecc9","weight":1}]},{"guid":"3f476837-4583-53e9-8ddf-eb940720a469","title":"A COG In The Machine - Using Cloud Optimised GeoTiffs to Query 24 Billion Pixels In Real-Time","subtitle":null,"slug":"bucharest-258-a-cog-in-the-machine-using-cloud-optimised-geotiffs-to-query-24-billion-pixels-in-real-time","link":"https://talks.2019.foss4g.org/bucharest/talk/SQF7YK/","description":"How do you find one pixel in a billion? \n\nCloud Optimized GeoTiffs are a new standard for raster data that support file-level access via the internet.

this talk, we will give an overview of the recent works that have occurred in the PROJ, libgeotiff and GDAL libraries regarding Coordinate Reference Systems (CRS). Those improvements have mostly taken place in the venerable PROJ library that has evolved over the last 30 years from handling “only” more than hundred of cartographic projections to becoming a full-fledged library for CRS management and transformations.\nPROJ 6 now supports OGC and ISO standards regarding object modeling (ISO-19111 / OGC Abstract topic 2), and their Well-Known Text representation (OGC WKT1, WKT2:2015 and latest WKT2:2018). A sqlite3-based database embeds the definitions coming from various authorities: EPSG, IGN-France and the ESRI projection engine. PROJ can now compute optimal and more accurate transformations between two CRS without necessarily using the ill-defined WGS84 pivot (“late-binding”), and support new CRS and transformations.\nWe will discuss the the adoption status of PROJ 6 by the rest of the OSGeo stack and present quickly how to migrate to this new version.\n\nNone","original_language":"eng","persons":["Even Rouault"],"tags":["bucharest","198","2019","General"],"view_count":193,"promoted":false,"date":"2019-08-28T00:00:00.000+02:00","release_date":"2019-08-29T02:00:00.000+02:00","updated_at":"2024-07-29T20:15:02.427+02:00","length":1537,"duration":1537,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/198-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/198-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/198-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/198-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-198-revamp-of-coordinate-reference-system-management-in-the-osgeo-c-c-stack-with-proj-and-gdal","url":"https://api.media.ccc.de/public/events/b05efa77-03a4-5ff9-a037-06d5aa2a1b6d","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7465,"event_guid":"d2b2bdd0-36fa-5ae1-aba0-a38960010e3b","weight":2},{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":7},{"event_id":7482,"event_guid":"89395e98-1ee1-5eee-ae26-cbaa54630177","weight":3},{"event_id":7484,"event_guid":"b4d6c8c6-688b-5273-aa8f-a2044128ac13","weight":4},{"event_id":7487,"event_guid":"6f1b8b15-b44a-592c-b3e9-96bd9e0fbce3","weight":3},{"event_id":7492,"event_guid":"f65e1c2f-8bde-5c89-a128-e113b0b9a3f6","weight":3},{"event_id":7518,"event_guid":"8773035b-d16c-5cf3-902d-43abc7e5dab7","weight":2},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":2},{"event_id":7552,"event_guid":"4c2f4b81-1316-502d-870c-dc39567b782e","weight":1},{"event_id":7553,"event_guid":"9f0999f8-6941-5308-b1a8-f094c738245f","weight":5},{"event_id":7562,"event_guid":"79cf5a8f-8601-533e-82c5-56626447534c","weight":2},{"event_id":7568,"event_guid":"7a848633-35e2-5b06-962e-c9cb71cf9762","weight":2},{"event_id":7574,"event_guid":"b3b2685b-8691-5c3a-bb1c-14d2038338cd","weight":5},{"event_id":7578,"event_guid":"d5d6bac8-cb8a-504a-9a3f-ced5c377e1bd","weight":5},{"event_id":7619,"event_guid":"21ffa487-5dfd-57d3-acce-8fd048ead7cf","weight":2},{"event_id":7623,"event_guid":"d7305220-5dac-5581-bf1b-14e735c39756","weight":5},{"event_id":7626,"event_guid":"227ae37a-41aa-53d7-944a-2e9b7c8d99a7","weight":5},{"event_id":7632,"event_guid":"99a39bf7-5c95-5bc3-947a-55e28aa0a042","weight":1},{"event_id":7652,"event_guid":"e04c27d0-8ff8-5bf4-b932-34db4e4fdf5b","weight":4},{"event_id":7663,"event_guid":"1b265f5f-a622-52e0-a2a4-88105aa09aba","weight":2},{"event_id":7669,"event_guid":"7627a093-69e4-5c72-b8b5-0f05c27ce815","weight":4},{"event_id":7674,"event_guid":"ac484924-85f6-5195-bf5b-9f689f24ef57","weight":5},{"event_id":7695,"event_guid":"5df0ebe1-cfe2-54c4-a0c8-40e35a6de826","weight":5},{"event_id":7701,"event_guid":"d3a697b4-8bc4-57ba-934c-2747fbec39ab","weight":2},{"event_id":7721,"event_guid":"9462ccbb-1601-5d12-8756-5e11e3134112","weight":4},{"event_id":7726,"event_guid":"5fabfcb3-0d99-553b-a6f8-5a6119513afc","weight":4},{"event_id":7733,"event_guid":"0ba5c644-2353-5225-972e-6e3958f74f3e","weight":6},{"event_id":7749,"event_guid":"5117b85e-052d-5b96-bcc3-f14e953b887a","weight":4},{"event_id":7753,"event_guid":"5f917971-56e2-5166-a686-07e384a9228d","weight":6},{"event_id":7756,"event_guid":"c4299de5-e39e-576d-93bb-7ae47fee42af","weight":4}]},{"guid":"81f32156-c1c3-5ee8-8fec-e5800350f677","title":"OGC standards development and the role of OSGeo","subtitle":null,"slug":"bucharest-276-ogc-standards-development-and-the-role-of-osgeo","link":"https://talks.2019.foss4g.org/bucharest/talk/3MKSF3/","description":"OGC and OSGeo have a long history of cooperation, since many years we work together through a Memorandum of Understanding, which amongst other aspects provides OSGeo to a certain extend access to the OGC standards development process.

High personnel turnover makes it difficult to maintain servers, and VSAT-only connectivity results in dial-up performance for both city and field locations. Despite this, there is a great need to communicate detailed GIS data beyond what can be printed on paper. To fill in this gap, REACH Initiative has been developing platforms that use mobile- \u0026 offline-first technologies to address these issues.\n\nThis talk will focus on a specific platform REACH has been developing to allow less technical users to make their own offline maps with minimal maintenance. This map CMS pulls data from a managed GraphQL service and generates progressive web apps using a static site generator with Mapbox GL templates. Emphasis will be placed on the big picture of how these pieces connect together.\n\nThis specific example will be framed in a larger discussion of how to best develop complex software for low-bandwidth environments. During over two year's worth of development in the field, it will tell the story of what different approaches were attempted, and why these failed in the humanitarian context from a performance and maintenance perspective.\n\nNone","original_language":"eng","persons":["Max Malynowsky"],"tags":["bucharest","133","2019","General"],"view_count":122,"promoted":false,"date":"2019-08-29T00:00:00.000+02:00","release_date":"2019-08-29T02:00:00.000+02:00","updated_at":"2025-04-18T22:00:05.079+02:00","length":1414,"duration":1414,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/133-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/133-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/133-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/133-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-133-user-generated-offline-maps-with-serverless-frameworks","url":"https://api.media.ccc.de/public/events/b744af16-2f4c-5151-bca1-91449f719965","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7492,"event_guid":"f65e1c2f-8bde-5c89-a128-e113b0b9a3f6","weight":3},{"event_id":7495,"event_guid":"bffc8bd9-0df8-5543-8c24-254c05092bbd","weight":3},{"event_id":7520,"event_guid":"2e1e926d-3eaa-5fa1-83b3-1a8e001df0c6","weight":3},{"event_id":7524,"event_guid":"f58c39cb-2250-51b5-8902-d52f713c934b","weight":3},{"event_id":7548,"event_guid":"8ca1b4b6-ee0c-5102-ab95-a978cd3b4d8c","weight":4},{"event_id":7557,"event_guid":"ab693aa0-5ac8-533f-aeca-a8d39a36e86c","weight":2},{"event_id":7694,"event_guid":"05466dda-8c63-57a3-a1ff-ebeff2abaa92","weight":3}]},{"guid":"742befe9-4856-57c3-816c-c9cf35661ece","title":"Reconsidering Default.

The implemented algorithms are parameterized by strategies that control the accuracy-efficiency trade-off. The proposed solutions work for 3 different coordinate systems (namely, cartesian, spherical and ellipsoidal) each of which comes with its own advantages and limitations.

close collaboration with UNICEF Uganda and GeoGecko, KCCA spearheaded the development of an online open source portal to provide a visual presentation of key social services available in Kampala. The tool is built on the backbone of four pillars aimed at (i) identifying key partners’ operations and the nature of their engagement in Kampala, (ii) mapping infrastructure points designed to deliver predetermined services (e.g. schools), (iii) summarizing parish level specific socio-economic profiles, and ultimately (iv) offer insight into the lives of young Ugandan adolescent girls accessing such service in Uganda’s capital city.\nThe tool is built with Open Source tools and can therefore easily be adopted to other projects, regions and be implemented in another context. \nDuring this presentation we will (i) walk through the portal and explain how it is created, (ii) describe how it is currently used, and most importantly (iii) discuss how it can be improved and adapted to other sectors at scale.\n\nNone","original_language":"eng","persons":["Lars Agerskov Christensen"],"tags":["bucharest","227","2019","General"],"view_count":11,"promoted":false,"date":"2019-08-29T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2021-11-09T12:00:15.808+01:00","length":1454,"duration":1454,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/227-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/227-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/227-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/227-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-227-social-protection-portal-kampala-on-open-source-portal-for-humanitarian-use","url":"https://api.media.ccc.de/public/events/6a5482fd-2b09-5bea-bea5-b48ba7e33cf3","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7251,"event_guid":"b69c19ce-7c89-4afd-9396-ea664f80dba7 ","weight":1},{"event_id":7516,"event_guid":"edcad3ee-627e-5a69-8432-c12c4a09173c","weight":2},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":2},{"event_id":7571,"event_guid":"ff3f8976-451e-5f00-bc69-fb2dea80b3bb","weight":1},{"event_id":7610,"event_guid":"08454950-b5fe-59f1-9a94-2f51780aef74","weight":1},{"event_id":7624,"event_guid":"69079f64-448d-55b5-9cb3-7089547c370d","weight":1},{"event_id":7626,"event_guid":"227ae37a-41aa-53d7-944a-2e9b7c8d99a7","weight":1},{"event_id":7630,"event_guid":"2922816b-f00a-5fc1-97e6-69df1a0c98ab","weight":1},{"event_id":7678,"event_guid":"c9058144-0344-5cdd-9e8d-228d9a6443f3","weight":2},{"event_id":7693,"event_guid":"7b831cc0-2092-52d2-bb54-f219e39a666f","weight":2},{"event_id":7696,"event_guid":"cf0c6d43-7a50-5d88-b6dd-db5aa818aff8","weight":1},{"event_id":7708,"event_guid":"f41c767d-1f3d-5e46-a477-1a9dde63e146","weight":2},{"event_id":7715,"event_guid":"664da34a-88d9-57c5-8b88-cdbfca55029b","weight":2},{"event_id":7736,"event_guid":"61205921-df6b-5dff-902b-9d757f719602","weight":2},{"event_id":7749,"event_guid":"5117b85e-052d-5b96-bcc3-f14e953b887a","weight":2}]},{"guid":"ff3f8976-451e-5f00-bc69-fb2dea80b3bb","title":"Planet - how GIS/RS users can leverage the product and services","subtitle":null,"slug":"bucharest-450-planet-how-gis-rs-users-can-leverage-the-product-and-services","link":"https://talks.2019.foss4g.org/bucharest/talk/JTYG8T/","description":"The talk presents the  Planet overview, with a focus on Planet’s mission and vision and how satellite data users \nleverage our products and services.

It’s also an early step to create a feedback loop where humans provide input to help us improve the quality and relevance of automatically derived features.\n\nNone","original_language":"eng","persons":["Edoardo Neerhut"],"tags":["bucharest","309","General"],"view_count":185,"promoted":false,"date":"2019-08-28T00:00:00.000+02:00","release_date":"2019-08-28T02:00:00.000+02:00","updated_at":"2024-10-07T16:00:02.675+02:00","length":1208,"duration":1208,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/309-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/309-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/309-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/309-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-309-mapillary2osm-openstreetmap-data-from-computer-vision","url":"https://api.media.ccc.de/public/events/c0174aef-c7a6-5d21-8dfe-e592c5a4eff3","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7465,"event_guid":"d2b2bdd0-36fa-5ae1-aba0-a38960010e3b","weight":5},{"event_id":7466,"event_guid":"98c0417b-cdfd-57b3-9411-14f9f465f5b9","weight":8},{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":9},{"event_id":7471,"event_guid":"3c2d5b68-ca8e-5c4e-9110-59ad868cfc70","weight":5},{"event_id":7482,"event_guid":"89395e98-1ee1-5eee-ae26-cbaa54630177","weight":4},{"event_id":7487,"event_guid":"6f1b8b15-b44a-592c-b3e9-96bd9e0fbce3","weight":5},{"event_id":7488,"event_guid":"0a3e23aa-d593-58cd-a3a1-7991e3a3a064","weight":4},{"event_id":7501,"event_guid":"a4aa4222-f2ca-5e0c-94f6-4c7a3595d1a2","weight":8},{"event_id":7504,"event_guid":"c54aa667-78de-55fb-85e7-60f2eaffd2a4","weight":8},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":13},{"event_id":7579,"event_guid":"0112454d-62b2-5132-8971-73c7fdb972d0","weight":5},{"event_id":7593,"event_guid":"6a8c04d0-d372-5f16-87a2-96f537854ebc","weight":5},{"event_id":7652,"event_guid":"e04c27d0-8ff8-5bf4-b932-34db4e4fdf5b","weight":6},{"event_id":7665,"event_guid":"f1f4f54c-e816-573f-a05d-7973f9f5d48e","weight":4},{"event_id":7673,"event_guid":"89f564bf-e743-5086-a372-478a49b0d7ce","weight":7},{"event_id":7701,"event_guid":"d3a697b4-8bc4-57ba-934c-2747fbec39ab","weight":3},{"event_id":7725,"event_guid":"63a63204-d0dd-57d5-aae3-d766a3be9d23","weight":5},{"event_id":7749,"event_guid":"5117b85e-052d-5b96-bcc3-f14e953b887a","weight":7},{"event_id":7756,"event_guid":"c4299de5-e39e-576d-93bb-7ae47fee42af","weight":6},{"event_id":7759,"event_guid":"2dbbceca-916a-5619-8d57-6bd9f57db57a","weight":10}]},{"guid":"3fc26cc4-962e-5f27-a92b-c01e86d12100","title":"MapML: The (new) \"map\" HTML element, now in MapServer, GDAL and OGR","subtitle":null,"slug":"bucharest-363-mapml-the-new-map-html-element-now-in-mapserver-gdal-and-ogr","link":"https://talks.2019.foss4g.org/bucharest/talk/9D7GAU/","description":"The W3C Maps for HTML Community Group is working to define a (new) \"map\" HTML element that would be used to define map contents in a web page and would be directly supported and rendered by web browsers in a standardized way. All this is done by building on existing standards such as WMS, WFS and Tile Services. In addition to standardizing the encoding and access to map elements in web browsers, this encoding also aims to make the map contents more easily discoverable and indexable by search bots on the Web.\n\nThis talk will start with an overview of the MapML draft specification, and then discuss the recent implementation of MapML in MapServer, GDAL and OGR. The goal of this initial implementation is to get MapML used in real life scenarios and to gather feedback from the community on the draft specification.

EnviDat actively implements the FAIR (Findability, Accessibility, Interoperability and Reusability) principles and provides a range of services in the area of research data management that were extensively described in [Iosifescu et al. (2018a)](https://doi.org/10.5334/dsj-2018-028). We continuously improve various aspects of open science support in EnviDat, including implementation of Jupyter Notebooks as documented in [Iosifescu et al. (2018b)](https://doi.org/10.7287/peerj.preprints.27211), thus improving the current situation defined by a “replication crisis”. \n\nIn [Iosifescu et al. (2015)](http://hdl.handle.net/2263/49954) we have presented several reasons for the increasing adoption of FOSS4G (free and open source software for geoinformatics) in academic research: not only the total cost of ownership, but also the growing stability and maturity of the recent open source software packages, the faster bug-fixing turnover, the increasing availability of professional support, and the flexibility to change and repurpose the open software to tackle new research challenges, among others. These reasons are still valid today, and consequently EnviDat trusts PostgreSQL/PostGIS and Apache Solr with the management of its spatial meta(data).\n\nIn this contribution, we discuss two novel drivers for the adoption of FOSS(4G) in environmental research: open science and reproducibility. Independent research replication at peer-review is facilitated by the immediate availability of the free and open source software, the absence of software licensing issues and the openness of the code even for older versions of a software. Moreover, researchers producing their own FOSS code can expect a wider distribution of the produced software. In EnviDat, open science support is supported by the combined publication of bundles of datasets and software as for example [Fraefel (2018)](https://doi.org/10.16904/envidat.49) or purely FOSS4G software as for example [Bont (2018)]( https://doi.org/10.16904/envidat.software.1). While Fraefel shows how scientists can complement data publication with additional analysis workflows, the work of Bont demonstrates the opening of a methodology for optimizing the geometric layout cable roads and makes it available for everyone as a plugin for QGIS.\n\nIn conclusion, supporting reproducibility of research in a portal such as EnviDat is a complex issue that can be simplified by the adoption of FOSS(4G). We would like to stress that reproducibility in science also consists of the transparency of methods and the precise documentation of all steps needed to achieve the published results. In these processes, open source software can play a key role.\n\nNone","original_language":"eng","persons":["Steffen Konrad","Ionuț Iosifescu Enescu","Lucía de Espona Pernas","Marielle Fraefel","Gian-Kasper Plattner","Rolf Meile","Dominik Haas-Artho","Thomas Kramer","Martin Hägeli","Leo Bont"],"tags":["bucharest","68","2019","Academic"],"view_count":46,"promoted":false,"date":"2019-08-29T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2024-11-09T22:00:03.096+01:00","length":1900,"duration":1900,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/68-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/68-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/68-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/68-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-68-open-science-knowledge-sharing-and-reproducibility-as-drivers-for-the-adoption-of-foss4g-in-environmental-research","url":"https://api.media.ccc.de/public/events/38fb4b40-3935-5dbc-b54a-551830e317d8","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":1},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":2},{"event_id":7532,"event_guid":"e7956d52-af40-563e-ae3e-1df491ad6591","weight":1},{"event_id":7550,"event_guid":"53494dbe-b19b-5e77-a2d1-9cb5a6d5447d","weight":1},{"event_id":7581,"event_guid":"f3a8dd85-9308-553a-928d-bfd47824fbd7","weight":1},{"event_id":7618,"event_guid":"6ed3f0f2-a47f-5229-b734-0c911d11f597","weight":1},{"event_id":7642,"event_guid":"c51c6100-e015-53bc-8296-486d5e4e3ce7","weight":1},{"event_id":7653,"event_guid":"2f97a6f3-e441-505a-8be2-e95554c44430","weight":2},{"event_id":7672,"event_guid":"1c58bd3e-15f6-51a3-af44-9d6a75f31556","weight":1},{"event_id":7681,"event_guid":"a1326956-88be-5af4-b747-5cefc95e8232","weight":1},{"event_id":7699,"event_guid":"3394a8b8-5954-531f-bbab-877ae065fcee","weight":1},{"event_id":7721,"event_guid":"9462ccbb-1601-5d12-8756-5e11e3134112","weight":1},{"event_id":7733,"event_guid":"0ba5c644-2353-5225-972e-6e3958f74f3e","weight":2},{"event_id":7755,"event_guid":"f651ccfa-c224-5cfa-b76b-f7b44b4ef563","weight":1}]},{"guid":"a68f321d-2709-5ede-8a20-aeb7f8d4a723","title":"Geodesic algorithms: an experimental study","subtitle":null,"slug":"bucharest-57-geodesic-algorithms-an-experimental-study","link":"https://talks.2019.foss4g.org/bucharest/talk/TANLXN/","description":"The figure of the Earth can be modelled either by a cartesian plane, a sphere or an (oblate) ellipsoid, in decreasing order with respect to the approximation quality. The shortest path between two points on such a surface is called a geodesic. Studying geodesic problems on ellipsoids dates back to Newton. However, the majority of open-source GIS systems today use methods on the cartesian plane. The main advantages of those approaches are simplicity of implementation and performance. On the other hand, those approaches come with a handicap: accuracy.\nWe experimentally study the accuracy-performance trade-offs of various methods for distance computation (as well as similar geodesic problems such as azimuth and area computation). We test projections paired with cartesian computations, spherical-trigonometric computations and a number of ellipsoidal methods such as [Andoyer'65] and [Thomas'70] formulas, [Vincenty'75] iterative method, great elliptic arc's method, and [Karney'15] series approximation. We also show that some methods from the bibliography (e.g. [Tseng'15]) are neither faster nor more accurate compared to the above list of methods and thus become redundant. For our experiments we use the open source libraries Boost Geometry and GeographicLib.  \nOur results are of independent interest since we are not aware of a similar experimental study. More interestingly, they can be used as a reference for practitioners that want to use the most efficient method with respect to some given accuracy.  \nGeodesic computations (such as distance computations) apart from being a fundamental problem in computational geometry and geography/geodesy are also building blocks for many higher level algorithms such as k-nearest neighbour problems, line interpolation, densification of geometries, area and buffer, to name a few.\n\n# References\n* Some experimental results can be found here: https://github.com/vissarion/geometry/wiki/Accuracy-and-performance-of-geographic-algorithms\n* A related talk (with some graphs on performance and accuracy) can be found here https://fosdem.org/2019/schedule/event/geo_boostgeometry\n* The source code of most of the algorithms of the study is in Boost Geometry: https://github.com/boostorg/geometry but we contain to our study GeographicLib https://geographiclib.sourceforge.io\n\nNone","original_language":"eng","persons":["Vissarion Fisikopoulos"],"tags":["bucharest","57","2019","Academic"],"view_count":102,"promoted":false,"date":"2019-08-30T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2025-04-21T01:00:02.981+02:00","length":1380,"duration":1380,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/57-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/57-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/57-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/57-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-57-geodesic-algorithms-an-experimental-study","url":"https://api.media.ccc.de/public/events/a68f321d-2709-5ede-8a20-aeb7f8d4a723","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":2521,"event_guid":"55a2a1d7-f022-4e5a-8d24-568e42b8dadd","weight":1},{"event_id":7409,"event_guid":"b4902bdb-38ab-5abb-9884-5efdb4bca02f","weight":1},{"event_id":7466,"event_guid":"98c0417b-cdfd-57b3-9411-14f9f465f5b9","weight":2},{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":1},{"event_id":7482,"event_guid":"89395e98-1ee1-5eee-ae26-cbaa54630177","weight":2},{"event_id":7487,"event_guid":"6f1b8b15-b44a-592c-b3e9-96bd9e0fbce3","weight":2},{"event_id":7492,"event_guid":"f65e1c2f-8bde-5c89-a128-e113b0b9a3f6","weight":1},{"event_id":7505,"event_guid":"5ac07c14-e2f1-5cba-a86f-047443848af5","weight":1},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":1},{"event_id":7527,"event_guid":"b05efa77-03a4-5ff9-a037-06d5aa2a1b6d","weight":2},{"event_id":7530,"event_guid":"27739ac4-67df-54da-a0f4-633bc7a9ac61","weight":1},{"event_id":7540,"event_guid":"835f3234-2e2a-5d75-a3f3-7c822e225d60","weight":2},{"event_id":7544,"event_guid":"8ca67675-1b3a-5c4f-8d7e-e212bd72945a","weight":1},{"event_id":7547,"event_guid":"a31e875c-a407-5233-a81b-d682a44e33b7","weight":1},{"event_id":7561,"event_guid":"1125685c-9fdc-5572-89c0-8bc80c7df3e0","weight":1},{"event_id":7572,"event_guid":"fb951433-b271-5884-b370-a8ef56393406","weight":2},{"event_id":7574,"event_guid":"b3b2685b-8691-5c3a-bb1c-14d2038338cd","weight":1},{"event_id":7577,"event_guid":"2b9d3727-6fec-552b-99b1-f240c64986b4","weight":2},{"event_id":7579,"event_guid":"0112454d-62b2-5132-8971-73c7fdb972d0","weight":2},{"event_id":7584,"event_guid":"41e880ab-ca8a-5a40-aeeb-4b75fb3a94d3","weight":2},{"event_id":7594,"event_guid":"9f3b41cc-dc93-55d8-a318-7b7740109b71","weight":2},{"event_id":7597,"event_guid":"5250fc42-6c79-5499-9029-87009757e5f5","weight":2},{"event_id":7605,"event_guid":"e8a71f0f-3fbc-5e20-9459-c17cd58bdf11","weight":1},{"event_id":7609,"event_guid":"64785b52-3c01-587f-ad49-224968c337df","weight":1},{"event_id":7619,"event_guid":"21ffa487-5dfd-57d3-acce-8fd048ead7cf","weight":2},{"event_id":7623,"event_guid":"d7305220-5dac-5581-bf1b-14e735c39756","weight":1},{"event_id":7629,"event_guid":"43e2163d-d0f7-5b45-945b-25dd8c57118b","weight":1},{"event_id":7638,"event_guid":"6cef82f8-4f16-5fcd-adf6-aae52595dcfa","weight":1},{"event_id":7657,"event_guid":"13347d51-f447-50a0-86b3-1e0833dedc68","weight":1},{"event_id":7677,"event_guid":"9ba1e879-6d50-5e4b-b3a1-5267a000b2ed","weight":2},{"event_id":7692,"event_guid":"3c0ea464-ce0e-5676-a977-075148d7bbdd","weight":2},{"event_id":7695,"event_guid":"5df0ebe1-cfe2-54c4-a0c8-40e35a6de826","weight":2},{"event_id":7726,"event_guid":"5fabfcb3-0d99-553b-a6f8-5a6119513afc","weight":3},{"event_id":7739,"event_guid":"9fb4a987-3f98-530a-9177-41099f13ddef","weight":1},{"event_id":7752,"event_guid":"78ceca87-11cf-598f-9ad3-100d9652a2b4","weight":1},{"event_id":7756,"event_guid":"c4299de5-e39e-576d-93bb-7ae47fee42af","weight":2}]},{"guid":"9cb9910c-3b3f-5cec-830b-24e93de3edc9","title":"Africa Bees -

The availability of these resources is mostly influenced by the erratic rainfall conditions that characterize the Sahelian climate. To reduce the vulnerability to critical events, pastoral communities need access to reliable information on pasture, water, climate, animals’ concentration and disease outbreaks. As they live and move in areas with poor to no internet connection, Action Against Hunger (ACF) developed a system where data is collected from herders using a Telerivet SMS gateway and stored in a cloud environment. An automated script then geocodes the responses and creates a shapefile for each survey, ready to be plugged into QGIS for analysis. Currently 109 focal point nomadic herdsmen are spread over 4 Sahelian countries (Mali, Burkina Faso, Senegal and Niger) to collect and inform more than 18 core indicators on the pastoral situation. Cartographic data is then published on a public and open source web platform and transmitted to herders through radio broadcasts.\n\nNone","original_language":"eng","persons":["Lambert Marie-Julie"],"tags":["bucharest","176","2019","General"],"view_count":74,"promoted":false,"date":"2019-08-29T00:00:00.000+02:00","release_date":"2019-08-29T02:00:00.000+02:00","updated_at":"2025-06-27T13:45:04.358+02:00","length":1318,"duration":1318,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/176-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/176-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/176-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/176-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-176-real-time-mapping-with-sms-where-there-is-no-internet","url":"https://api.media.ccc.de/public/events/7ce19c2c-7bc3-5ba7-b454-b383a7c58c6c","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":4883,"event_guid":"ea27b2dc-d558-4fab-8406-a9db30930f8f","weight":1},{"event_id":6825,"event_guid":"dfb37b89-29a0-5314-9824-03c2689cdeed","weight":1},{"event_id":7368,"event_guid":"e1b56229-fb1e-480c-9691-c137ec11ee51","weight":1},{"event_id":7390,"event_guid":"ca134284-32df-48e0-b811-42c79dc71fa0","weight":1},{"event_id":7453,"event_guid":"ffa61ddc-7493-5c90-8976-ca25cf368bd0","weight":1},{"event_id":7466,"event_guid":"98c0417b-cdfd-57b3-9411-14f9f465f5b9","weight":1},{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":2},{"event_id":7472,"event_guid":"d021f555-141a-58f6-a21b-a787b1c84188","weight":3},{"event_id":7479,"event_guid":"5cb82c9e-bc84-54e2-a40d-60b78f35ef46","weight":1},{"event_id":7482,"event_guid":"89395e98-1ee1-5eee-ae26-cbaa54630177","weight":2},{"event_id":7487,"event_guid":"6f1b8b15-b44a-592c-b3e9-96bd9e0fbce3","weight":2},{"event_id":7494,"event_guid":"1b36ea18-1b2c-5dae-9a88-b36f57683b7c","weight":1},{"event_id":7512,"event_guid":"88c1d544-049b-5622-b197-03b8894a39f7","weight":2},{"event_id":7515,"event_guid":"b744af16-2f4c-5151-bca1-91449f719965","weight":1},{"event_id":7518,"event_guid":"8773035b-d16c-5cf3-902d-43abc7e5dab7","weight":2},{"event_id":7521,"event_guid":"95aa7cdb-5057-54aa-9dbc-511e4ee508c4","weight":2},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":2},{"event_id":7542,"event_guid":"7e354528-0b5a-512d-be47-bdc7447bb93b","weight":2},{"event_id":7548,"event_guid":"8ca1b4b6-ee0c-5102-ab95-a978cd3b4d8c","weight":2},{"event_id":7550,"event_guid":"53494dbe-b19b-5e77-a2d1-9cb5a6d5447d","weight":1},{"event_id":7552,"event_guid":"4c2f4b81-1316-502d-870c-dc39567b782e","weight":1},{"event_id":7554,"event_guid":"20bb70f9-e0ab-5d46-9e99-71cd75e04251","weight":3},{"event_id":7555,"event_guid":"a641fc9b-2eb6-5580-8acc-4236e227de4e","weight":2},{"event_id":7558,"event_guid":"175e2989-1005-5266-8928-9bb1247bf423","weight":1},{"event_id":7595,"event_guid":"1b45aaaa-70dc-5f27-8b7b-64dc0fe409a5","weight":3},{"event_id":7598,"event_guid":"1a86892c-4740-5da9-9c01-f6781f3edc22","weight":1},{"event_id":7606,"event_guid":"c0ebaf1b-03d8-53f4-81d1-b5b306e93c60","weight":2},{"event_id":7610,"event_guid":"08454950-b5fe-59f1-9a94-2f51780aef74","weight":2},{"event_id":7713,"event_guid":"14dfde19-5a7a-59ee-8470-e75266353678","weight":2},{"event_id":7718,"event_guid":"4ae662a0-789b-56b6-a357-ed2384226e9d","weight":2},{"event_id":7724,"event_guid":"583daa21-2358-57db-8ee9-d7e1572e4c8f","weight":1},{"event_id":7740,"event_guid":"503efde4-1e72-51f5-b508-4ca91a364086","weight":1}]},{"guid":"6f455f9f-a9a4-502e-8e73-b0208dbe8427","title":"FOSS tools for modelling natural hazards:  the HortonMachine library","subtitle":null,"slug":"bucharest-149-foss-tools-for-modelling-natural-hazards-the-hortonmachine-library","link":"https://talks.2019.foss4g.org/bucharest/talk/DTWPFR/","description":"The climate change and the recent extreme events occurred all over the world draw again the attention to the natural hazards both for prevention and for management aspects.

intention to facilitate faster establishment of cadastral databases, different projects were initiated to support rapid automated approach for boundary extraction from remotely sensed imagery. Such project is the EU funded “its4land”, developed as a joint venture between several organizations including University of Twente. Despite the current advancement of the modern segmentation algorithms, there are imperfections in the output that have to be further manually filtered out. Therefore, a QGIS plugin called BoundaryDelineation was designed and developed to support an interactive delineation of visible (cadastral) boundaries to speed-up the process. The plugin supports the full pipeline of loading, picking and drawing segments, and saving to a remote server the final validated output, which allows rapid reduction of the mouse clicks compared to manual delineation, which affects the overall speed of creation of cadastral entities.\nThe presentation will consist of a general overview of the its4land project, and main focus on the usage of the

In combination with advances in data creation and processing as well as the definition of standards like CityGML, new ways of modeling urban potentials have been developed. This lead to numerous approaches estimating roof-top solar photovoltaic (PV) production. However, in recent years due to research in building materials, the façades became more attractive and feasible for PV electricity production.\nThis paper describes results on the development of an completely FOSS-based approach to assess the electricity production potential by building façade PV. To estimate solar irradiation we followed the hemispherical viewshed approach described by Fu, 1999. Combining it with an approach to dissect walls into regular 3D point grids (1 meter spacing) we calculate the sun visibility (each hour) and the sky viewshed throughout the year. This results in direct and diffuse irradiation for every wall point. To generate the electricity potential, the irradiation values are summed up for the wall points and are fed into an economic model. This is driven by technical parameters of the installation, such as module efficiency, installation and maintenance costs, figures about payback tariffs and envisaged module lifetime. \nThe overall result is a city-wide PV suitability and electricity production potential map of every building façade.\nThe processing is based on a city model in the CityGML format using the 3DCityDB database and the spatial processing functionalities of PostGIS. A set of Python scripts has been developed as a central control instance. The scripts control the processing of direct and diffuse irradiation as well as clear sky irradiation relying on the external “pvlib” Python library. Furthermore, we use the scripts to manage parallel processing of queries against the database to achieve scalability and improved performance. The parallelisation is done by processing single building walls. We run a case study with approximately 7000 single wall elements to process. We identified so far one of the major bottlenecks of the approach. This are the calculations of sun visibility for every wall point per timestamp (intersection with surrounding buildings) which takes per wall several minutes to process depending on the number of points per wall.\nSince we implemented a parallel processing of the walls running on a 80-core dedicated server machine, the completion for an entire city of 3 million wall points uses a decent amount of time for the given size of data set. Here we describe a scalable and highly parallelised approach which can be easily implemented through standard tools and libraries. This open up now for distributed approaches using multiple database servers for even better scalability.\n\nNone","original_language":"eng","persons":["Christian

coordination of increasingly faster development of geospatial Free and Open Source Software and more longer term oriented standards presents some challenges which have been identified and taken up by key organizations of the domain. OGC and OSGeo have a long history of cooperation, since many years we work together through a Memorandum of Understanding, which amongst other aspects provides OSGeo to a certain extend access to the OGC standards development process. The cooperation is meant to bring in requirements, ideas and expertise from the OSGeo community to the OGC programs and processes and provides the OSGeo community with an insight into the current developments of open standards.\n\nThe Overview presentation will provide a short insight into the OGC programs and processes and will explain the idea and development approaches for the OGC baseline.

Improvements in the spatial and temporal resolutions lead to an increase of the entire data volume up to 5 PBs. Additionally to the sheer amount of data, meteorological and climate data have a certain complexity, especially for “non-expert” users, as data can have up to five dimensions and two time dimensions.\n\nThe current situation shows that a full, free and open data policy is one important prerequisite, but the key to fully unleash the potential is making the data ‘accessible’. If open data is not accessible, it becomes open data that is locked away in large data silos. \n\nHowever, making meteorological and climate data “accessible” means more than just improving data access. It requires improvements and developments along the entire data processing chain, including the development of example workflows and reproducible training materials as well as developing / enhancing mainstream open-source software tools. In this context, the FOSS4G spirit is vital.\n\nThis talk puts the spotlight on open meteorological and climate data. Current ‘accessibility’ challenges and future needs will be discussed in order to make open meteorological and climate data better accessible to everyone.\n\nNone","original_language":"eng","persons":["Julia

A plugin to facilitate hybrid open source/proprietary environments. We’re planning a similar tool for QGIS. We'll present the current status and challenges in this presentation. Main goal of this plugin is to ‘facilitate publication to an open OGC/INSPIRE SDI as easy as possible’. To facilitate this we apply various principles:\n\n- Publish data as layer/coverage/featuretype in GeoServer or Mapserver\n- Require minimal metadata to comply to OGC/INSPIRE\n- Register datasets in a catalog with proper linkage to/from the data services\n- Migrate data to GeoPackage, Postgres or reference existing data\n\nAn important aspect to focus on is metadata management. Last year an initiative started to improve metadata management in QGIS. Some major improvements have been introduced. The Bridge tool will benefit from these developments. New options are the ability to import, export, validate and publish INSPIRE/ISO metadata. Improve SLD creation (for usage in Geoserver). Proper linkage between the catalog and the gis server.\n\nNone","original_language":"eng","persons":["Jody Garnett","Paul van Genuchten"],"tags":["bucharest","257","2019","General"],"view_count":167,"promoted":false,"date":"2019-08-28T00:00:00.000+02:00","release_date":"2019-08-29T02:00:00.000+02:00","updated_at":"2025-06-18T17:15:04.741+02:00","length":1405,"duration":1405,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/257-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/257-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/257-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/257-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-257-one-click-data-publishing-for-qgis-to-support-ogc-inspire","url":"https://api.media.ccc.de/public/events/390f46cd-b632-5bbd-b24c-463606723436","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7458,"event_guid":"f5ef88a8-0fb3-4310-bb04-358db302a13b","weight":1},{"event_id":7466,"event_guid":"98c0417b-cdfd-57b3-9411-14f9f465f5b9","weight":4},{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":3},{"event_id":7468,"event_guid":"43d9cc0e-3fb9-55b2-a3a1-b9cfbe928e23","weight":2},{"event_id":7478,"event_guid":"ae1cdec5-93fe-5638-a167-faa6e81cf9c6","weight":4},{"event_id":7480,"event_guid":"603a5649-724a-53d7-ac20-ff7d520696d3","weight":4},{"event_id":7505,"event_guid":"5ac07c14-e2f1-5cba-a86f-047443848af5","weight":2},{"event_id":7514,"event_guid":"0d63b0b4-259d-5114-8c8f-18604b514f7d","weight":4},{"event_id":7520,"event_guid":"2e1e926d-3eaa-5fa1-83b3-1a8e001df0c6","weight":4},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":3},{"event_id":7530,"event_guid":"27739ac4-67df-54da-a0f4-633bc7a9ac61","weight":4},{"event_id":7531,"event_guid":"eeabc00d-ba6f-58f2-91d9-1bde01e1c643","weight":2},{"event_id":7548,"event_guid":"8ca1b4b6-ee0c-5102-ab95-a978cd3b4d8c","weight":3},{"event_id":7552,"event_guid":"4c2f4b81-1316-502d-870c-dc39567b782e","weight":5},{"event_id":7554,"event_guid":"20bb70f9-e0ab-5d46-9e99-71cd75e04251","weight":3},{"event_id":7559,"event_guid":"69de3e04-de0f-5325-9862-023143b3252b","weight":1},{"event_id":7561,"event_guid":"1125685c-9fdc-5572-89c0-8bc80c7df3e0","weight":4},{"event_id":7564,"event_guid":"faf1a4fd-2d2d-5622-a95a-c6488eeff404","weight":2},{"event_id":7579,"event_guid":"0112454d-62b2-5132-8971-73c7fdb972d0","weight":4},{"event_id":7582,"event_guid":"95c65e38-a93e-5306-a9c6-b1cdc197bb58","weight":1},{"event_id":7609,"event_guid":"64785b52-3c01-587f-ad49-224968c337df","weight":3},{"event_id":7652,"event_guid":"e04c27d0-8ff8-5bf4-b932-34db4e4fdf5b","weight":3},{"event_id":7661,"event_guid":"afb75703-96a4-5546-b1fa-493154ef35ae","weight":1},{"event_id":7662,"event_guid":"a8fbf537-cbe1-5f17-aa73-97d64132f660","weight":2},{"event_id":7663,"event_guid":"1b265f5f-a622-52e0-a2a4-88105aa09aba","weight":4},{"event_id":7682,"event_guid":"3da56fe5-5d22-565b-849f-591265220120","weight":2},{"event_id":7694,"event_guid":"05466dda-8c63-57a3-a1ff-ebeff2abaa92","weight":2},{"event_id":7701,"event_guid":"d3a697b4-8bc4-57ba-934c-2747fbec39ab","weight":3},{"event_id":7711,"event_guid":"ca42c4dc-9dda-5b88-abe8-f843062db935","weight":3},{"event_id":7743,"event_guid":"c393e563-c11d-5111-aa92-fc579ac7ecc9","weight":4}]},{"guid":"e48d8c2a-d423-5568-8be0-45464da7dfce","title":"Streaming and rendering the Turin 3D geospatial content through  GIS and BIM integration","subtitle":null,"slug":"bucharest-157-streaming-and-rendering-the-turin-3d-geospatial-content-through-gis-and-bim-integration","link":"https://talks.2019.foss4g.org/bucharest/talk/3EDL7D/","description":"We started working on BIM (Building Information Model) and GIS integration in 2016.

Nowadays, the Municipality of Turin uses the successful integration of GIS and BIM objects for internal facility management  of thirty public owned buildings in Turin.  Adopting the [3D Tiles](https://github.com/AnalyticalGraphicsInc/3d-tiles) OGC standard, we stream and render online the full BIM and photogrammetric reconstruction of Turin buildings and monuments. Also, using open source tools and open data, we extend the value of digital BIM through visualisation and integration with available cartography.\nThis allows us  to fully benefit of BIM potentiality in terms of data and object management. Furthermore, we display our maps and models using open source virtual globes, an easily accessible environment.\n\nNone","original_language":"eng","persons":["Fabrizio Massara (CSI Piemonte)","Fabrizio Provera","Adelaide Ramassotto  (CSI Piemonte)"],"tags":["bucharest","157","2019","General"],"view_count":97,"promoted":false,"date":"2019-08-30T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2025-06-25T16:45:05.409+02:00","length":1620,"duration":1620,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/157-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/157-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/157-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/157-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-157-streaming-and-rendering-the-turin-3d-geospatial-content-through-gis-and-bim-integration","url":"https://api.media.ccc.de/public/events/e48d8c2a-d423-5568-8be0-45464da7dfce","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7466,"event_guid":"98c0417b-cdfd-57b3-9411-14f9f465f5b9","weight":3},{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":1},{"event_id":7470,"event_guid":"f1310bbb-4baa-57ff-84e7-3594fe29c5e3","weight":1},{"event_id":7471,"event_guid":"3c2d5b68-ca8e-5c4e-9110-59ad868cfc70","weight":1},{"event_id":7473,"event_guid":"feda735f-5467-56f0-9ddf-55cefdf60199","weight":5},{"event_id":7482,"event_guid":"89395e98-1ee1-5eee-ae26-cbaa54630177","weight":4},{"event_id":7484,"event_guid":"b4d6c8c6-688b-5273-aa8f-a2044128ac13","weight":1},{"event_id":7487,"event_guid":"6f1b8b15-b44a-592c-b3e9-96bd9e0fbce3","weight":1},{"event_id":7488,"event_guid":"0a3e23aa-d593-58cd-a3a1-7991e3a3a064","weight":6},{"event_id":7500,"event_guid":"e72bec3a-da22-50b9-a6d6-11cedeb37917","weight":2},{"event_id":7514,"event_guid":"0d63b0b4-259d-5114-8c8f-18604b514f7d","weight":3},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":1},{"event_id":7525,"event_guid":"9cb9910c-3b3f-5cec-830b-24e93de3edc9","weight":1},{"event_id":7526,"event_guid":"fd5614a8-535f-5069-8f69-3a9983d37830","weight":6},{"event_id":7540,"event_guid":"835f3234-2e2a-5d75-a3f3-7c822e225d60","weight":1},{"event_id":7548,"event_guid":"8ca1b4b6-ee0c-5102-ab95-a978cd3b4d8c","weight":1},{"event_id":7550,"event_guid":"53494dbe-b19b-5e77-a2d1-9cb5a6d5447d","weight":6},{"event_id":7563,"event_guid":"eac1e444-e3c2-52b6-aea9-c14f53a6ae4b","weight":4},{"event_id":7570,"event_guid":"5a2c55f3-b3bc-5c4d-894a-cc7e5b887f56","weight":1},{"event_id":7585,"event_guid":"3e149633-f405-5e9b-850c-b0934537b6d8","weight":3},{"event_id":7604,"event_guid":"b0001b70-6e5d-50e1-aaa4-51345e1d7a65","weight":5},{"event_id":7608,"event_guid":"13e2ef4d-8375-580b-a797-c54a85faa0aa","weight":1},{"event_id":7627,"event_guid":"1afdcbac-7132-5769-8368-712bf4a8163a","weight":1},{"event_id":7645,"event_guid":"efd996c1-5096-5b23-bf42-3dd6818dc072","weight":1},{"event_id":7667,"event_guid":"4bc8bbe5-cb04-5a2b-b441-a696be055948","weight":1},{"event_id":7672,"event_guid":"1c58bd3e-15f6-51a3-af44-9d6a75f31556","weight":7},{"event_id":7673,"event_guid":"89f564bf-e743-5086-a372-478a49b0d7ce","weight":5},{"event_id":7681,"event_guid":"a1326956-88be-5af4-b747-5cefc95e8232","weight":4},{"event_id":7694,"event_guid":"05466dda-8c63-57a3-a1ff-ebeff2abaa92","weight":2},{"event_id":7704,"event_guid":"d4397024-b341-5a6f-ab92-b0f157931833","weight":1},{"event_id":7710,"event_guid":"9bce8e1a-0dc8-5c82-977c-23dccd115e89","weight":3}]},{"guid":"76554f37-f382-50da-a02a-3656b5a70ed2","title":"Open Green Map - a geospatial tool for sustainable living","subtitle":null,"slug":"bucharest-285-open-green-map-a-geospatial-tool-for-sustainable-living","link":"https://talks.2019.foss4g.org/bucharest/talk/W7JXB9/","description":"Created to serve a locally-led global map making network, the original Open Green Map (OGM) - www.opengreenmap.org, a social mapping platform, was launched by Green Map System in 2009. In the decade since, an 8 language interface and mobile site collector are among the features that attracted users in 40 countries. Dubbed ‘open’ as sites could be enhanced by the public, more than 40,000 sites were added to the OGM locally on 600 unique maps. Many of these maps became the backbone for local engagement projects and led to interactive spin off editions, print maps, experiences and media projects. \n\nAlready recognized in 65 countries, Green Map Icons bring a wide range of sustainability resources to light. These lively symbols identify, promote and link local resources in an eye-catching, easy to grasp manner that systematically connects themes and places in meaningful way.\n\nGreen Map has always served a mixed group of participants, including NGOs, schools and local governments.

is facing a huge challenge to formalize land tenure in an efficient, massive and decentralized manner. The Swiss cooperation provides all different actors with a common conceptual and technical framework. On the one hand, a Colombian profile [1] of the LADM (ISO:19152) was built, constituting the core of a Spatial Data Infrastructure for Land Administration (IDE-AT). \n\nOn the other hand, the INTERLIS language [2] guarantees interoperability for data formats and systems and is the basis of a free software ecosystem around the project: QField [3] offers automatically generated forms to capture both geographic and alphanumeric data, as well as their associated documents. In the office, operators use a QGIS plugin called “LADM_COL Assistant” [4] to migrate and structure field data into a LADM-COL database. The same tool is employed by cadastral authorities to receive, validate (both topologically and logically), review and integrate the data incorporating changes into official systems. Finally, the new data is disposed in the IDE-AT to all actors of land administration.\n\nThe project not only develops new software, but also contributes code to base projects such as ili2db [5], QGIS Model Baker [6] and QGIS [7] itself.\n\nNone","original_language":"eng","persons":["Germán Carrillo"],"tags":["bucharest","297","2019","General"],"view_count":53,"promoted":false,"date":"2019-08-29T00:00:00.000+02:00","release_date":"2019-08-29T02:00:00.000+02:00","updated_at":"2025-07-05T01:00:03.197+02:00","length":1025,"duration":1025,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/297-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/297-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/297-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/297-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-297-modernization-of-land-administration-in-colombia-based-on-foss4g-and-standards","url":"https://api.media.ccc.de/public/events/deadde12-6ce3-5394-aeec-531251a711a2","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":2},{"event_id":7468,"event_guid":"43d9cc0e-3fb9-55b2-a3a1-b9cfbe928e23","weight":1},{"event_id":7477,"event_guid":"9227fcf3-b7b2-5a7a-b135-3e7a18341a82","weight":1},{"event_id":7480,"event_guid":"603a5649-724a-53d7-ac20-ff7d520696d3","weight":1},{"event_id":7487,"event_guid":"6f1b8b15-b44a-592c-b3e9-96bd9e0fbce3","weight":2},{"event_id":7517,"event_guid":"ef1a3ce2-61bf-53e1-8f97-acb738c219f9","weight":1},{"event_id":7524,"event_guid":"f58c39cb-2250-51b5-8902-d52f713c934b","weight":1},{"event_id":7530,"event_guid":"27739ac4-67df-54da-a0f4-633bc7a9ac61","weight":1},{"event_id":7540,"event_guid":"835f3234-2e2a-5d75-a3f3-7c822e225d60","weight":2},{"event_id":7542,"event_guid":"7e354528-0b5a-512d-be47-bdc7447bb93b","weight":1},{"event_id":7544,"event_guid":"8ca67675-1b3a-5c4f-8d7e-e212bd72945a","weight":1},{"event_id":7547,"event_guid":"a31e875c-a407-5233-a81b-d682a44e33b7","weight":1},{"event_id":7549,"event_guid":"7b9c8b02-7d33-5172-b0ea-841a26d389b0","weight":1},{"event_id":7550,"event_guid":"53494dbe-b19b-5e77-a2d1-9cb5a6d5447d","weight":1},{"event_id":7553,"event_guid":"9f0999f8-6941-5308-b1a8-f094c738245f","weight":1},{"event_id":7554,"event_guid":"20bb70f9-e0ab-5d46-9e99-71cd75e04251","weight":2},{"event_id":7557,"event_guid":"ab693aa0-5ac8-533f-aeca-a8d39a36e86c","weight":1},{"event_id":7588,"event_guid":"12d4492d-6339-54e7-bcd6-fb12cc7f8422","weight":2},{"event_id":7597,"event_guid":"5250fc42-6c79-5499-9029-87009757e5f5","weight":2},{"event_id":7624,"event_guid":"69079f64-448d-55b5-9cb3-7089547c370d","weight":1},{"event_id":7632,"event_guid":"99a39bf7-5c95-5bc3-947a-55e28aa0a042","weight":1},{"event_id":7640,"event_guid":"82b144e3-2fb0-5184-89b7-4594567be536","weight":1},{"event_id":7641,"event_guid":"d5b00dcc-d898-5a3a-bc8f-8e62d492bf4e","weight":1},{"event_id":7644,"event_guid":"82b0e18e-fa65-5616-95ee-20b22c1b5e41","weight":2},{"event_id":7652,"event_guid":"e04c27d0-8ff8-5bf4-b932-34db4e4fdf5b","weight":1},{"event_id":7656,"event_guid":"cdcc0bac-ebad-566c-b691-c54010212a86","weight":1},{"event_id":7659,"event_guid":"81f32156-c1c3-5ee8-8fec-e5800350f677","weight":1},{"event_id":7667,"event_guid":"4bc8bbe5-cb04-5a2b-b441-a696be055948","weight":1},{"event_id":7681,"event_guid":"a1326956-88be-5af4-b747-5cefc95e8232","weight":1},{"event_id":7711,"event_guid":"ca42c4dc-9dda-5b88-abe8-f843062db935","weight":1},{"event_id":7725,"event_guid":"63a63204-d0dd-57d5-aae3-d766a3be9d23","weight":1},{"event_id":7726,"event_guid":"5fabfcb3-0d99-553b-a6f8-5a6119513afc","weight":2}]},{"guid":"17f484f5-c4e2-58da-a7ec-cb18c3e85cd4","title":"Como llego to infinity and beyond","subtitle":null,"slug":"bucharest-409-como-llego-to-infinity-and-beyond","link":"https://talks.2019.foss4g.org/bucharest/talk/DAFRXE/","description":"Buenos Aires  has a wide public transport network that includes more than 180 bus lines, 7 trains, 6 subway lines and 195 km of bicycle lanes that it offers to 4.5 million residents. and different alternative visitors when they travel.

It is available for Android and IOS and has more than 700,000 active users who do 1 million searches per week.\nIt integrates real-time information on subways, trains and buses so that users know when the next transport will arrive and also the different rates to provide more transparent information and allow residents and visitors to make better decisions. The objectives for 2019 are to include predictions for all bus lines, currently only available for those who are already sensorized, to include the services of the Metropolitan Area and to open the code of the application to the community.

This is what the project I will present sets out to do. \nWorking on an open source project can sometimes make it seem like compromises around performance or user centric design are reasonable. What if you don't want to compromise in any of these 2 directions? By using an appropriate and modern tech stack, along with generative programming techniques, we hope to introduce a new approach for creating GIS applications.\nThis talk will introduce how the new Open Green Map app works, and advantages of using DLang and Ember for a GIS app. We will also take a look at challenges that arise in relation to implementing GIS applications while having plenty of constraints around resources, and when helpful open source libraries are missing.

These significant advances in image classification, object detection and image segmentation have profound implications for foundational mapping applications. Recent open source initiatives such as SpaceNet have strived to direct more research and development towards remote sensing applications. GIS practitioners need to understand and engage the research community to help structure the application of these new techniques against geospatial problems. tt is difficult translate mission requirements to machine learning evaluation metrics, and vice versa. For example, in the computer vision community, most results are described by certain image specific metrics such as mAP, F1Score, Precision and Recall.  Alternatively, a GIS practitioner may want to incorporate machine learning capabilities into their workflow, but not know what level of performance is necessary for the specific mission. We will discuss a framework for defining levels of practitioners augmentation that will allow end-user groups and machine learning researchers to better understand each other and help direct the

global 3D map works with data from various sources: DEMs, orthomosaics, vectors or even 3D city models. The data is acquired by diverse sensors and processing techniques and varies vastly in resolution and geospatial coverage. Need for partial updates may arise as more recent or higher resolution data becomes available. Integrating all this data into a single, meaningful cartographic or VR product gives rise to the data fusion problem on an ever growing scale. VTS geospatial software stack provides a simple yet powerful way to tackle common 3D data fusion scenarios. In this talk, we will provide a hands-on demonstration.\n\nNone","original_language":"eng","persons":["Tomas Kavan"],"tags":["bucharest","202","2019","General"],"view_count":45,"promoted":false,"date":"2019-08-29T00:00:00.000+02:00","release_date":"2019-08-29T02:00:00.000+02:00","updated_at":"2025-05-05T15:30:06.538+02:00","length":1493,"duration":1493,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/202-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/202-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/202-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/202-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-202-from-planetary-scale-to-street-level-detail-instant-3d-map-data-fusion-with-vts","url":"https://api.media.ccc.de/public/events/1b36ea18-1b2c-5dae-9a88-b36f57683b7c","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":6825,"event_guid":"dfb37b89-29a0-5314-9824-03c2689cdeed","weight":1},{"event_id":7361,"event_guid":"977957d7-ef42-4ea0-8380-b9a48bd583f0","weight":1},{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":2},{"event_id":7469,"event_guid":"c0174aef-c7a6-5d21-8dfe-e592c5a4eff3","weight":1},{"event_id":7473,"event_guid":"feda735f-5467-56f0-9ddf-55cefdf60199","weight":2},{"event_id":7479,"event_guid":"5cb82c9e-bc84-54e2-a40d-60b78f35ef46","weight":1},{"event_id":7482,"event_guid":"89395e98-1ee1-5eee-ae26-cbaa54630177","weight":4},{"event_id":7487,"event_guid":"6f1b8b15-b44a-592c-b3e9-96bd9e0fbce3","weight":2},{"event_id":7488,"event_guid":"0a3e23aa-d593-58cd-a3a1-7991e3a3a064","weight":3},{"event_id":7491,"event_guid":"7ce19c2c-7bc3-5ba7-b454-b383a7c58c6c","weight":1},{"event_id":7495,"event_guid":"bffc8bd9-0df8-5543-8c24-254c05092bbd","weight":1},{"event_id":7501,"event_guid":"a4aa4222-f2ca-5e0c-94f6-4c7a3595d1a2","weight":1},{"event_id":7504,"event_guid":"c54aa667-78de-55fb-85e7-60f2eaffd2a4","weight":1},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":2},{"event_id":7550,"event_guid":"53494dbe-b19b-5e77-a2d1-9cb5a6d5447d","weight":2},{"event_id":7552,"event_guid":"4c2f4b81-1316-502d-870c-dc39567b782e","weight":1},{"event_id":7554,"event_guid":"20bb70f9-e0ab-5d46-9e99-71cd75e04251","weight":1},{"event_id":7555,"event_guid":"a641fc9b-2eb6-5580-8acc-4236e227de4e","weight":1},{"event_id":7558,"event_guid":"175e2989-1005-5266-8928-9bb1247bf423","weight":1},{"event_id":7756,"event_guid":"c4299de5-e39e-576d-93bb-7ae47fee42af","weight":2}]},{"guid":"9227fcf3-b7b2-5a7a-b135-3e7a18341a82","title":"Composing and securing spatial data interfaces.

platform helps you build a spatial data infrastructure quickly and easily. Powered using open source components for a scalable solution focused on freedom rather than fees.   \n\nGC2/Vidi comprises two software projects:   \n- GC2 – makes it easy to deploy PostGIS, MapServer, QGIS Server, MapCache, Elasticsearch, GDAL/OGR. And offers an easy-to-use browser application to configure the software stack.   \n- Vidi – a modern take on browser GIS. It is the front-end client for GC2.\n\nThe GC2/Vidi project is released under GPL and accepted as an OSGeo Community Project last year.    \n\nThe first part of the talk gives a brief overview of the platform and summarizes the capabilities it has to offer. In the second part the browser GIS named Vidi will be reviewed with emphasis on the new offline capabilities. This comprises the possibilities to use the web app and access/edit data without network, which makes Vidi well suited for field work in areas without good 3G/4G coverage. The talk will include a short demonstration and give a walkthrough of the modern browser technologies used including Service Workers, IndexedDB and StorageManager.

patterns of recent disasters in Korea such as typhoons, mountain fires and earthquakes are becoming increasingly complex and extensive. At the same time, there have been repeated problems with the government's ability of disaster response system. It is important to look at the disaster from a unified perspective in order to reduce the damage that will occur from the disaster and promote recovery. In addition, the integration of the disaster management agency's situation-specific work process and information is one of the important parts for rapid response to the situation and reduction of damages. However, as most of the information used to response with disasters is temporarily used, there is a lack of periodic updates or management systems. Therefore, the continuation and clarity of information up to the recovery stage are unclear, and no definite recovery is supported for the disaster affected areas. In this study, the implementation manual and history of the situation response to major national disasters in Korea are analyzed to identify problems in response to existing disaster situations.\n\nNone","original_language":"eng","persons":["Jinyi

Starting from the importance of having a good and clear tile set to making your own sprites and glyphs with command line tools and software like Inkscape and Gimp.\nAfter that we show some trick to add animation with Turf.js and D3.js. Like placing random hot air balloons all over your map! \n\nVector tiles are on the cutting edge of technology and creativity, we combine both to show you the endless possibilities that vector tiles offer!\n\nNone","original_language":"eng","persons":["Niene Boeijen"],"tags":["bucharest","339","2019","General"],"view_count":173,"promoted":false,"date":"2019-08-30T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2024-05-13T09:15:02.860+02:00","length":1257,"duration":1257,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/339-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/339-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/339-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/339-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-339-how-to-make-a-crafty-vector-tile-map-custom-tiles-the-perfect-sprite-animating-stuff-and-random-hot-air-balloons-","url":"https://api.media.ccc.de/public/events/b0001b70-6e5d-50e1-aaa4-51345e1d7a65","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7466,"event_guid":"98c0417b-cdfd-57b3-9411-14f9f465f5b9","weight":3},{"event_id":7469,"event_guid":"c0174aef-c7a6-5d21-8dfe-e592c5a4eff3","weight":4},{"event_id":7488,"event_guid":"0a3e23aa-d593-58cd-a3a1-7991e3a3a064","weight":6},{"event_id":7492,"event_guid":"f65e1c2f-8bde-5c89-a128-e113b0b9a3f6","weight":2},{"event_id":7497,"event_guid":"ee2c0473-7931-5239-85f0-0385fb68054e","weight":1},{"event_id":7501,"event_guid":"a4aa4222-f2ca-5e0c-94f6-4c7a3595d1a2","weight":6},{"event_id":7504,"event_guid":"c54aa667-78de-55fb-85e7-60f2eaffd2a4","weight":3},{"event_id":7508,"event_guid":"90c767f8-cbe3-587d-a2b8-ee879b7e8b45","weight":1},{"event_id":7514,"event_guid":"0d63b0b4-259d-5114-8c8f-18604b514f7d","weight":6},{"event_id":7517,"event_guid":"ef1a3ce2-61bf-53e1-8f97-acb738c219f9","weight":5},{"event_id":7520,"event_guid":"2e1e926d-3eaa-5fa1-83b3-1a8e001df0c6","weight":1},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":1},{"event_id":7524,"event_guid":"f58c39cb-2250-51b5-8902-d52f713c934b","weight":6},{"event_id":7526,"event_guid":"fd5614a8-535f-5069-8f69-3a9983d37830","weight":6},{"event_id":7530,"event_guid":"27739ac4-67df-54da-a0f4-633bc7a9ac61","weight":4},{"event_id":7534,"event_guid":"3fc26cc4-962e-5f27-a92b-c01e86d12100","weight":4},{"event_id":7550,"event_guid":"53494dbe-b19b-5e77-a2d1-9cb5a6d5447d","weight":5},{"event_id":7552,"event_guid":"4c2f4b81-1316-502d-870c-dc39567b782e","weight":9},{"event_id":7556,"event_guid":"c9b9934c-1cec-518c-ab2f-6a70ee5622f0","weight":1},{"event_id":7573,"event_guid":"347ab764-8ae3-58fe-87a0-18dca9880c63","weight":4},{"event_id":7607,"event_guid":"d0794cae-d707-584c-8879-6c438a603486","weight":3},{"event_id":7610,"event_guid":"08454950-b5fe-59f1-9a94-2f51780aef74","weight":1},{"event_id":7614,"event_guid":"7347a409-8f11-53a7-b855-39fcf0d8c2ae","weight":5},{"event_id":7618,"event_guid":"6ed3f0f2-a47f-5229-b734-0c911d11f597","weight":7},{"event_id":7624,"event_guid":"69079f64-448d-55b5-9cb3-7089547c370d","weight":1},{"event_id":7625,"event_guid":"bd14d233-85f2-5064-8f3d-5693392a48e4","weight":5},{"event_id":7629,"event_guid":"43e2163d-d0f7-5b45-945b-25dd8c57118b","weight":2},{"event_id":7639,"event_guid":"9b3ad47a-e457-5428-b6ca-170addd9bf22","weight":6},{"event_id":7672,"event_guid":"1c58bd3e-15f6-51a3-af44-9d6a75f31556","weight":4},{"event_id":7681,"event_guid":"a1326956-88be-5af4-b747-5cefc95e8232","weight":3},{"event_id":7682,"event_guid":"3da56fe5-5d22-565b-849f-591265220120","weight":8},{"event_id":7692,"event_guid":"3c0ea464-ce0e-5676-a977-075148d7bbdd","weight":3},{"event_id":7694,"event_guid":"05466dda-8c63-57a3-a1ff-ebeff2abaa92","weight":3},{"event_id":7698,"event_guid":"61a1baea-9b7c-5f64-bef2-094b291f77fd","weight":1},{"event_id":7707,"event_guid":"8f9b67d8-fd60-522f-9a5b-6f0f81626e5c","weight":3},{"event_id":7710,"event_guid":"9bce8e1a-0dc8-5c82-977c-23dccd115e89","weight":12},{"event_id":7726,"event_guid":"5fabfcb3-0d99-553b-a6f8-5a6119513afc","weight":5},{"event_id":7733,"event_guid":"0ba5c644-2353-5225-972e-6e3958f74f3e","weight":4},{"event_id":7744,"event_guid":"e48d8c2a-d423-5568-8be0-45464da7dfce","weight":5}]},{"guid":"23bc1246-3fcb-5ce4-ac80-f8c176a25d97","title":"Linking geospatial free and open-source technologies with big data in biodiversity research","subtitle":null,"slug":"bucharest-287-linking-geospatial-free-and-open-source-technologies-with-big-data-in-biodiversity-research","link":"https://talks.2019.foss4g.org/bucharest/talk/7BFHNF/","description":"There were no slides recorded due to a system failure. We are sorry for that! Understanding and predicting the distribution of life on Earth represent major research tasks in the face of global environmental change. These tasks often require the integration and analysis of big and diverse datasets that reflect properties of wild organisms and their abiotic environment across space. I will demonstrate the use of geospatial free and open-source technologies for exploring, analysing and predicting biodiversity patterns across the globe, focusing primarily on the geography and drivers of genetic diversity in terrestrial mammals. I will also stress the importance of data sharing in nature conservation through interactive visualisation frameworks.\n\nNone","original_language":"eng","persons":["Spyros

about the news of fires in the amazon forest and may have a lot of other questions to ask. There are many questions and many different analyses to be made. For the purposes of this presentation, I will propose the following question: “Is the amazon forest being burned in large rates?”\n\nI will demonstrate a geoprocessing task using unwieldy data from the NASA FIRMS system (MODIS and VIIRS) and FOSS4G tools to try to answer the proposed question. What I will NOT do is discuss politics, ecology, or causes and effects. This is a complex subject and I believe one should ask questions focused on the decision one has to make. What are you trying to decide? What questions should you ask to help you in your decision? Maybe this presentation will provide you with a workflow and a few tools to do your own research.\n\nNone","original_language":"eng","persons":["Daniel Araújo Miranda"],"tags":["bucharest","516","2019","General"],"view_count":241,"promoted":false,"date":"2019-08-30T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2024-01-11T15:00:07.035+01:00","length":1578,"duration":1578,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/516-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/516-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/516-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/516-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-516-the-return-of-crazy-data-fires-in-the-amazon-forest","url":"https://api.media.ccc.de/public/events/771fc01c-25ee-5202-abbe-0b993a5e7ace","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":3},{"event_id":7504,"event_guid":"c54aa667-78de-55fb-85e7-60f2eaffd2a4","weight":4},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":3},{"event_id":7553,"event_guid":"9f0999f8-6941-5308-b1a8-f094c738245f","weight":3},{"event_id":7579,"event_guid":"0112454d-62b2-5132-8971-73c7fdb972d0","weight":5},{"event_id":7623,"event_guid":"d7305220-5dac-5581-bf1b-14e735c39756","weight":6},{"event_id":7624,"event_guid":"69079f64-448d-55b5-9cb3-7089547c370d","weight":2},{"event_id":7652,"event_guid":"e04c27d0-8ff8-5bf4-b932-34db4e4fdf5b","weight":2},{"event_id":7669,"event_guid":"7627a093-69e4-5c72-b8b5-0f05c27ce815","weight":3},{"event_id":7695,"event_guid":"5df0ebe1-cfe2-54c4-a0c8-40e35a6de826","weight":4},{"event_id":7707,"event_guid":"8f9b67d8-fd60-522f-9a5b-6f0f81626e5c","weight":3},{"event_id":7709,"event_guid":"936a0a3d-27d2-5bb7-a59a-336837047e72","weight":4},{"event_id":7749,"event_guid":"5117b85e-052d-5b96-bcc3-f14e953b887a","weight":2},{"event_id":7755,"event_guid":"f651ccfa-c224-5cfa-b76b-f7b44b4ef563","weight":3},{"event_id":7756,"event_guid":"c4299de5-e39e-576d-93bb-7ae47fee42af","weight":6},{"event_id":7758,"event_guid":"d7541c86-83fd-55c3-8843-f64e30b8aa55","weight":3}]},{"guid":"c393e563-c11d-5111-aa92-fc579ac7ecc9","title":"SHOGun, GeoServer \u0026 QGIS Integration: Manage WebGIS Applications from your Desktop","subtitle":null,"slug":"bucharest-199-shogun-geoserver-qgis-integration-manage-webgis-applications-from-your-desktop","link":"https://talks.2019.foss4g.org/bucharest/talk/ZL3PGE/","description":"SHOGun is an Open Source WebGIS framework, that is widely used in private companies, public administrations and also research projects. \nSHOGun combines user-, data- and application management through a webfrontend, like many others do. \nLearning new workflows and familiarizing yourself with new application environments is a big challenge for many users. Therefore, possibilities should be created to make the changeover easier for users and to link new technologies with existing ones.  \nIn order to bring desktop GIS and webbased GIS systems cloer together, we developped the  QGIS plug-in \"SHOGun Editor\". \nThe talk will show how SHOGun-based WebGIS applications and GeoServer served layers can be administered in QGIS with regard to adding and styling layers and applications.\n\nThe plugin uses both, the SHOGun and the GeoServer REST API. Using the SHOGun editor, the most central entities layers and applications can be administered almost completely. This includes the creation of new projects/applications as well as the addition and styling of layers. SHOGun-Editor provides the extensive editing options of QGIS also for web applications with a modern, stable and secured backend and helps to setup a pure Open Source based Geodata-I\n\nNone","original_language":"eng","persons":["Till Adams"],"tags":["bucharest","199","2019","General"],"view_count":328,"promoted":false,"date":"2019-08-30T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2025-06-10T09:00:03.657+02:00","length":1370,"duration":1370,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/199-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/199-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/199-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/199-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-199-shogun-geoserver-qgis-integration-manage-webgis-applications-from-your-desktop","url":"https://api.media.ccc.de/public/events/c393e563-c11d-5111-aa92-fc579ac7ecc9","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":6828,"event_guid":"a8574a07-3399-5976-a09c-4be0e6a43305","weight":1},{"event_id":7466,"event_guid":"98c0417b-cdfd-57b3-9411-14f9f465f5b9","weight":29},{"event_id":7468,"event_guid":"43d9cc0e-3fb9-55b2-a3a1-b9cfbe928e23","weight":2},{"event_id":7471,"event_guid":"3c2d5b68-ca8e-5c4e-9110-59ad868cfc70","weight":2},{"event_id":7480,"event_guid":"603a5649-724a-53d7-ac20-ff7d520696d3","weight":21},{"event_id":7487,"event_guid":"6f1b8b15-b44a-592c-b3e9-96bd9e0fbce3","weight":12},{"event_id":7497,"event_guid":"ee2c0473-7931-5239-85f0-0385fb68054e","weight":2},{"event_id":7510,"event_guid":"ab6c65d7-f9df-563f-b9bb-e36c128e9ab4","weight":7},{"event_id":7517,"event_guid":"ef1a3ce2-61bf-53e1-8f97-acb738c219f9","weight":15},{"event_id":7520,"event_guid":"2e1e926d-3eaa-5fa1-83b3-1a8e001df0c6","weight":8},{"event_id":7524,"event_guid":"f58c39cb-2250-51b5-8902-d52f713c934b","weight":4},{"event_id":7530,"event_guid":"27739ac4-67df-54da-a0f4-633bc7a9ac61","weight":16},{"event_id":7536,"event_guid":"9f921eab-53c5-5ce7-9489-45a586162248","weight":11},{"event_id":7552,"event_guid":"4c2f4b81-1316-502d-870c-dc39567b782e","weight":12},{"event_id":7553,"event_guid":"9f0999f8-6941-5308-b1a8-f094c738245f","weight":4},{"event_id":7554,"event_guid":"20bb70f9-e0ab-5d46-9e99-71cd75e04251","weight":2},{"event_id":7573,"event_guid":"347ab764-8ae3-58fe-87a0-18dca9880c63","weight":1},{"event_id":7577,"event_guid":"2b9d3727-6fec-552b-99b1-f240c64986b4","weight":2},{"event_id":7595,"event_guid":"1b45aaaa-70dc-5f27-8b7b-64dc0fe409a5","weight":1},{"event_id":7606,"event_guid":"c0ebaf1b-03d8-53f4-81d1-b5b306e93c60","weight":1},{"event_id":7635,"event_guid":"a134c0ce-1291-54b1-a56e-547284a962f0","weight":1},{"event_id":7661,"event_guid":"afb75703-96a4-5546-b1fa-493154ef35ae","weight":1},{"event_id":7663,"event_guid":"1b265f5f-a622-52e0-a2a4-88105aa09aba","weight":6},{"event_id":7669,"event_guid":"7627a093-69e4-5c72-b8b5-0f05c27ce815","weight":6},{"event_id":7671,"event_guid":"a38570ce-3943-5e91-aa70-1333d5d9cc48","weight":1},{"event_id":7677,"event_guid":"9ba1e879-6d50-5e4b-b3a1-5267a000b2ed","weight":1},{"event_id":7679,"event_guid":"6510f93b-924b-5975-be42-3dc7c336f020","weight":14},{"event_id":7695,"event_guid":"5df0ebe1-cfe2-54c4-a0c8-40e35a6de826","weight":8},{"event_id":7701,"event_guid":"d3a697b4-8bc4-57ba-934c-2747fbec39ab","weight":1},{"event_id":7713,"event_guid":"14dfde19-5a7a-59ee-8470-e75266353678","weight":2},{"event_id":7721,"event_guid":"9462ccbb-1601-5d12-8756-5e11e3134112","weight":1},{"event_id":7732,"event_guid":"771fc01c-25ee-5202-abbe-0b993a5e7ace","weight":1},{"event_id":7738,"event_guid":"ecbd87e4-3c54-5fbe-b5fd-aefc02e7c95d","weight":1},{"event_id":7749,"event_guid":"5117b85e-052d-5b96-bcc3-f14e953b887a","weight":8},{"event_id":7750,"event_guid":"123bf2f0-6f17-5563-96c7-430cfe28dd0d","weight":1},{"event_id":7759,"event_guid":"2dbbceca-916a-5619-8d57-6bd9f57db57a","weight":1}]},{"guid":"e7956d52-af40-563e-ae3e-1df491ad6591","title":"Publication of Inspire Datasets as Linked Data","subtitle":null,"slug":"bucharest-441-publication-of-inspire-datasets-as-linked-data","link":"https://talks.2019.foss4g.org/bucharest/talk/8QJHCM/","description":"In order to increase interoperability and facilitate the reusing of geospatial data, it is proposed a methodology of publishing INSPIRE-compliant datasets as Linked Data, using the RDF format and various ontologies such as the ones derived from the ARE3NA for the Annex I themes, or GeoSPARQL from the OGC. This methodology would cover the whole process of generating the RDF triples from GML sources, setting up a triple-store to persist the information, and issuing SPARQL queries to the exposed endpoint. A working example would be presented using the Spanish CNIG endpoint, where several datasets from the Annex I are hosted. Then a series of queries joining external information from other endpoint, like DBPedia or GeoNames, would be used as a mean to demonstrate the interoperable capabilities and the potential applications to enrich spatial data, extract meaningful insights from it and use it to support information systems.\n\nNone","original_language":"eng","persons":["Enrique Soriano","Rodríguez Pascual Antonio Federico"],"tags":["bucharest","441","2019","General"],"view_count":39,"promoted":false,"date":"2019-08-28T00:00:00.000+02:00","release_date":"2019-08-29T02:00:00.000+02:00","updated_at":"2025-01-02T02:30:02.878+01:00","length":1419,"duration":1419,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/441-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/441-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/441-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/441-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-441-publication-of-inspire-datasets-as-linked-data","url":"https://api.media.ccc.de/public/events/e7956d52-af40-563e-ae3e-1df491ad6591","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":6796,"event_guid":"51d3b894-e061-570d-8d94-d0ce984b37c4","weight":1},{"event_id":6812,"event_guid":"604049b2-25f5-52f1-b98a-8c7cfb08a1e8","weight":1},{"event_id":7478,"event_guid":"ae1cdec5-93fe-5638-a167-faa6e81cf9c6","weight":1},{"event_id":7500,"event_guid":"e72bec3a-da22-50b9-a6d6-11cedeb37917","weight":2},{"event_id":7509,"event_guid":"2ecaf4b8-9654-58a3-afce-5771d68ac94f","weight":2},{"event_id":7529,"event_guid":"ceaf6b0d-7e1a-5262-a7ae-61533de03fde","weight":4},{"event_id":7533,"event_guid":"bff8e480-f2e6-5fb7-a945-fed5e6b06f77","weight":1},{"event_id":7538,"event_guid":"18d0bdd8-5bdf-536e-9a51-5479ba1be544","weight":2},{"event_id":7541,"event_guid":"222dc305-9e4a-5085-83c2-d78971f07dea","weight":2},{"event_id":7552,"event_guid":"4c2f4b81-1316-502d-870c-dc39567b782e","weight":1},{"event_id":7581,"event_guid":"f3a8dd85-9308-553a-928d-bfd47824fbd7","weight":1},{"event_id":7614,"event_guid":"7347a409-8f11-53a7-b855-39fcf0d8c2ae","weight":1},{"event_id":7616,"event_guid":"23bc1246-3fcb-5ce4-ac80-f8c176a25d97","weight":1},{"event_id":7621,"event_guid":"8e5e286c-0e3c-5c18-9122-dee8e92752cc","weight":1},{"event_id":7642,"event_guid":"c51c6100-e015-53bc-8296-486d5e4e3ce7","weight":1},{"event_id":7653,"event_guid":"2f97a6f3-e441-505a-8be2-e95554c44430","weight":1},{"event_id":7675,"event_guid":"9e54b705-cdd9-5485-8bec-d392c97aee70","weight":1},{"event_id":7682,"event_guid":"3da56fe5-5d22-565b-849f-591265220120","weight":1},{"event_id":7699,"event_guid":"3394a8b8-5954-531f-bbab-877ae065fcee","weight":1},{"event_id":7703,"event_guid":"38fb4b40-3935-5dbc-b54a-551830e317d8","weight":1},{"event_id":7707,"event_guid":"8f9b67d8-fd60-522f-9a5b-6f0f81626e5c","weight":1},{"event_id":7710,"event_guid":"9bce8e1a-0dc8-5c82-977c-23dccd115e89","weight":2},{"event_id":7729,"event_guid":"9d030aa8-27aa-509b-913f-ee9eff97257b","weight":2},{"event_id":7731,"event_guid":"dd3327f8-7f66-5844-bc78-9dede7aeb710","weight":1},{"event_id":7736,"event_guid":"61205921-df6b-5dff-902b-9d757f719602","weight":2},{"event_id":7751,"event_guid":"bb1806af-1579-5ee7-916e-099ef1bb74f1","weight":1},{"event_id":7755,"event_guid":"f651ccfa-c224-5cfa-b76b-f7b44b4ef563","weight":1},{"event_id":7756,"event_guid":"c4299de5-e39e-576d-93bb-7ae47fee42af","weight":1},{"event_id":7758,"event_guid":"d7541c86-83fd-55c3-8843-f64e30b8aa55","weight":2}]},{"guid":"222dc305-9e4a-5085-83c2-d78971f07dea","title":"I3S – an open standard to bring 3D to Web, Desktop and Mobile platforms","subtitle":null,"slug":"bucharest-438-i3s-an-open-standard-to-bring-3d-to-web-desktop-and-mobile-platforms","link":"https://talks.2019.foss4g.org/bucharest/talk/TEMWSB/","description":"Indexed 3d Scene Layers (I3S), is an Open Geospatial Consortium (OGC) standard for streaming massive amounts of heterogeneously distributed geospatial data for an interactive experience for web, desktop, mobile and embedded clients. \nI3S supports storage and transmission of very large data consisting of millions of discrete 3D objects with attributes, integrated surface meshes and point cloud data covering vast geographic areas.

The standard land values have to be derived comprehensively for different land use within a district. These are mainly residential areas, mixed-use zones (residential and commercial areas), industrial areas, cropland, grassland and forestry. The standard land values serve the taxation authorities to rate the hereditary real estate and also will play a major role for the future property tax (Löhr, 2018). With the help of Geographic Information Systems (GIS) all the necessary data for the derivation of the standard land values could be analyzed. This data consists of cadastral information (ALKIS) (AdV, 2005) for each municipality district like streets, buildings, land parcels, land development plans as well as geocoded data (Bill, 2016) about real estate transactions. \nAccording to the INSPIRE (Infrastructure for Spatial Information in Europe) directive (European Parliament, 2007) which aims to create a European spatial data infrastructure for a transparent common environmental policy the geodata representing the standard land values will be provided in the Web with services to query, visualize and download the datasets. The following work contributes to both requirements, the statutory determination of the standard land values answering the lawful necessity and the setting up of the generated geodata in the Web according to the demanded transparency of the INSPIRE directive. \nThis thesis describes the development of automatizing the process of implementing, selecting, aggregating and layouting the relevant objects of the ALKIS data in an Open Source GIS (QGIS) via Python language. The standard land values will be visualized and presented in Web GIS (Seip et al, 2017). Therefore three different Web Clients will be compared according to performance and editing capabilities: QGIS Web Client (Open Source), Lizmap (Open Source) and ArcGIS Online (commercial). Additionally the two different Web GIS server solutions, QGIS Server and ArcGIS Online, will be described and evaluated.\n\nNone","original_language":"eng","persons":["Heike Weippert","Franz-Josef Behr","Hamidreza Ostadabbas"],"tags":["bucharest","71","2019","Academic"],"view_count":178,"promoted":false,"date":"2019-08-29T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2025-02-19T00:30:05.881+01:00","length":1640,"duration":1640,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/71-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/71-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/71-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/71-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-71-database-transformation-cadastre-automatic-data-processing-in-qgis-and-implementation-in-web-gis","url":"https://api.media.ccc.de/public/events/82b0e18e-fa65-5616-95ee-20b22c1b5e41","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7389,"event_guid":"ed4b6c75-14f4-49fe-a11e-3762bd6b54e3","weight":1},{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":1},{"event_id":7468,"event_guid":"43d9cc0e-3fb9-55b2-a3a1-b9cfbe928e23","weight":1},{"event_id":7471,"event_guid":"3c2d5b68-ca8e-5c4e-9110-59ad868cfc70","weight":1},{"event_id":7477,"event_guid":"9227fcf3-b7b2-5a7a-b135-3e7a18341a82","weight":1},{"event_id":7480,"event_guid":"603a5649-724a-53d7-ac20-ff7d520696d3","weight":1},{"event_id":7487,"event_guid":"6f1b8b15-b44a-592c-b3e9-96bd9e0fbce3","weight":2},{"event_id":7517,"event_guid":"ef1a3ce2-61bf-53e1-8f97-acb738c219f9","weight":1},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":3},{"event_id":7524,"event_guid":"f58c39cb-2250-51b5-8902-d52f713c934b","weight":1},{"event_id":7539,"event_guid":"deadde12-6ce3-5394-aeec-531251a711a2","weight":2},{"event_id":7542,"event_guid":"7e354528-0b5a-512d-be47-bdc7447bb93b","weight":2},{"event_id":7544,"event_guid":"8ca67675-1b3a-5c4f-8d7e-e212bd72945a","weight":1},{"event_id":7547,"event_guid":"a31e875c-a407-5233-a81b-d682a44e33b7","weight":3},{"event_id":7549,"event_guid":"7b9c8b02-7d33-5172-b0ea-841a26d389b0","weight":1},{"event_id":7557,"event_guid":"ab693aa0-5ac8-533f-aeca-a8d39a36e86c","weight":1},{"event_id":7564,"event_guid":"faf1a4fd-2d2d-5622-a95a-c6488eeff404","weight":2},{"event_id":7574,"event_guid":"b3b2685b-8691-5c3a-bb1c-14d2038338cd","weight":1},{"event_id":7588,"event_guid":"12d4492d-6339-54e7-bcd6-fb12cc7f8422","weight":1},{"event_id":7597,"event_guid":"5250fc42-6c79-5499-9029-87009757e5f5","weight":1},{"event_id":7606,"event_guid":"c0ebaf1b-03d8-53f4-81d1-b5b306e93c60","weight":1},{"event_id":7624,"event_guid":"69079f64-448d-55b5-9cb3-7089547c370d","weight":3},{"event_id":7643,"event_guid":"63e1996e-b296-55cb-9fd6-4e4d22e878f6","weight":1},{"event_id":7652,"event_guid":"e04c27d0-8ff8-5bf4-b932-34db4e4fdf5b","weight":1},{"event_id":7663,"event_guid":"1b265f5f-a622-52e0-a2a4-88105aa09aba","weight":3},{"event_id":7667,"event_guid":"4bc8bbe5-cb04-5a2b-b441-a696be055948","weight":2},{"event_id":7705,"event_guid":"c2575631-1db8-5188-b684-d153774a171e","weight":1},{"event_id":7720,"event_guid":"60e9b22b-78f2-5213-a4bc-76adada4fa2a","weight":1},{"event_id":7721,"event_guid":"9462ccbb-1601-5d12-8756-5e11e3134112","weight":2},{"event_id":7749,"event_guid":"5117b85e-052d-5b96-bcc3-f14e953b887a","weight":3}]},{"guid":"feda735f-5467-56f0-9ddf-55cefdf60199","title":"A digital 3D maquette on country scale with pointclouds, postgis, 3D tiles and cesium","subtitle":null,"slug":"bucharest-325-a-digital-3d-maquette-on-country-scale-with-pointclouds-postgis-3d-tiles-and-cesium","link":"https://talks.2019.foss4g.org/bucharest/talk/SJH3VL/","description":"More open pointcloud data is released every year and with it there is an increasing request  for automatically generated large scale digital maquettes that can be used in city-planning, environmental modelling and 3D data-analysis. We will show how we use a pipeline of OS software that goes from pointclouds and cadastral data to a full scale 3D maquette of your country. Processing happens mostly in postgres and takes typically a couple of minutes per square km.\n\nIncluded in the talk is:\n* introduction of some python-scripts for pointcloud-processing\n* adoption of procedural language in postgres\n* advanced use of postgis (voronoi, sfcgal etc)\n* generating 3D tiles\n* styling a maquette in cesium\n\nThe presentation will be fast paced and includes a range of technical details but should be understandable for the average person. It includes code examples and live demo's. In the end you will have an understanding of available software (both new and existing), do's and don'ts in generating 3D data with OSS and contemplations on how to use a digital 3D maquette.\n\nNone","original_language":"eng","persons":["Tom van Tilburg \u0026 Anne Blankert"],"tags":["bucharest","325","General"],"view_count":202,"promoted":false,"date":"2019-08-28T00:00:00.000+02:00","release_date":"2019-08-29T02:00:00.000+02:00","updated_at":"2025-03-21T00:45:03.459+01:00","length":1528,"duration":1528,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/325-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/325-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/325-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/325-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-325-a-digital-3d-maquette-on-country-scale-with-pointclouds-postgis-3d-tiles-and-cesium","url":"https://api.media.ccc.de/public/events/feda735f-5467-56f0-9ddf-55cefdf60199","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":6058,"event_guid":"7fe2a84b-bbed-4a4e-80fb-85b581c14b13","weight":1},{"event_id":6422,"event_guid":"e8385c89-d33a-42d8-afb6-8ae28fe5c89d","weight":1},{"event_id":7384,"event_guid":"8e743367-04a1-4232-ab03-a54fc210e548","weight":1},{"event_id":7462,"event_guid":"bc0ea171-a661-56f9-a518-e32c84bbcf8b","weight":1},{"event_id":7465,"event_guid":"d2b2bdd0-36fa-5ae1-aba0-a38960010e3b","weight":1},{"event_id":7466,"event_guid":"98c0417b-cdfd-57b3-9411-14f9f465f5b9","weight":8},{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":9},{"event_id":7471,"event_guid":"3c2d5b68-ca8e-5c4e-9110-59ad868cfc70","weight":6},{"event_id":7477,"event_guid":"9227fcf3-b7b2-5a7a-b135-3e7a18341a82","weight":5},{"event_id":7478,"event_guid":"ae1cdec5-93fe-5638-a167-faa6e81cf9c6","weight":1},{"event_id":7480,"event_guid":"603a5649-724a-53d7-ac20-ff7d520696d3","weight":1},{"event_id":7482,"event_guid":"89395e98-1ee1-5eee-ae26-cbaa54630177","weight":15},{"event_id":7484,"event_guid":"b4d6c8c6-688b-5273-aa8f-a2044128ac13","weight":4},{"event_id":7487,"event_guid":"6f1b8b15-b44a-592c-b3e9-96bd9e0fbce3","weight":10},{"event_id":7488,"event_guid":"0a3e23aa-d593-58cd-a3a1-7991e3a3a064","weight":11},{"event_id":7495,"event_guid":"bffc8bd9-0df8-5543-8c24-254c05092bbd","weight":1},{"event_id":7497,"event_guid":"ee2c0473-7931-5239-85f0-0385fb68054e","weight":1},{"event_id":7499,"event_guid":"de560d64-70a3-518c-b12d-5b639a1c7b97","weight":1},{"event_id":7510,"event_guid":"ab6c65d7-f9df-563f-b9bb-e36c128e9ab4","weight":3},{"event_id":7511,"event_guid":"12a2750d-c71a-5b02-b16b-a66cea7b33ac","weight":1},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":4},{"event_id":7524,"event_guid":"f58c39cb-2250-51b5-8902-d52f713c934b","weight":1},{"event_id":7526,"event_guid":"fd5614a8-535f-5069-8f69-3a9983d37830","weight":10},{"event_id":7529,"event_guid":"ceaf6b0d-7e1a-5262-a7ae-61533de03fde","weight":1},{"event_id":7530,"event_guid":"27739ac4-67df-54da-a0f4-633bc7a9ac61","weight":1},{"event_id":7550,"event_guid":"53494dbe-b19b-5e77-a2d1-9cb5a6d5447d","weight":10},{"event_id":7662,"event_guid":"a8fbf537-cbe1-5f17-aa73-97d64132f660","weight":3},{"event_id":7672,"event_guid":"1c58bd3e-15f6-51a3-af44-9d6a75f31556","weight":6}]},{"guid":"8ca1b4b6-ee0c-5102-ab95-a978cd3b4d8c","title":"CNN-based tools in GRASS GIS","subtitle":null,"slug":"bucharest-181-cnn-based-tools-in-grass-gis","link":"https://talks.2019.foss4g.org/bucharest/talk/8TET9M/","description":"Object detection and image segmentation have always been a big task in the field of geospatial sciences.

Downtime is a key performance indicator, however so are service functionality and performance. The OGC has created a Quality of Service and Experience Domain Working Group to research and provide best practices, illustrating the importance of this topic.\n\nThere are many HTTP monitoring tools that track general status and uptime. However, OGC web services often have custom reporting errors which are usually not considered. Examples include custom errors or null results based on database issues. In these cases a generic uptime checker will assume the service is functioning correctly though the response says otherwise.\n\nThese issues illustrate the value of OGC-aware service monitoring and have been missing from the FOSS4G ecosystem. Until now.\n\nGeoHealthCheck (GHC) is an OGC web services monitoring framework. GHC is written in Python as part of the GeoPython GitHub Organization. GHC is a monitoring engine that executes “health checks” and a web application which reports on key performance indicators.

EFAS provides information to the national hydrological services when there is a danger that critical flood levels might be excedeed. EFAS displays the results of the flood forecasts through a web application that grants end-users the ability to contribute and share information. \nA part of information provided by EFAS is restricted to the EFAS users (real time forecasts), non real time forecasts are freely accessible for all the users. Though the EFAS interface flood warnings emails are send the the EFAS partners in order to inform them of a possible upcoming event. There are strict criteria on the activation and deactivation of these warnings.

Transparency and asynchronicity for example are among the principles laying the basis for our day-to-day work. We are part of the Opensource community at large, and we have a very similar organization.\n\nDuring this talk, we explain the way we work, our motivations and and how a distributed team made of

Inventory ESTimation and Analysis system (nFIESTA) is an open-source PostgreSQL extension capable to produce estimates of target parameters describing the condition of forests and its development.\nThe specificity of the nFIESTA estimation system is that it allows for an analysis of large datasets sourced by National Forest Inventories (NFIs) of many (not only European) countries. Such an integrated database contains sample plot data that use to be collected following a number of different sampling and survey designs, with spatial distribution and timing that vary from country to country.\nUsing such a system the estimates of forest and landscape parameters can be obtained at a level of detail starting from a relatively small areas - as small as several hundreds of sq. kilometers. From the temporal point of view, the current implementation supports estimations for periods of one calendar year or longer.

The activities are organized into four working groups, referred to as ‘spirals’; Spiral one for geo-portal and system infrastructure, Spiral two for capacity building, Spiral three for geo-analytic functions, and Spiral four for geospatial data collection. \n\nThis talk will cover an overall introduction of the UN Open GIS initiative including the vision, strategies, technical roadmaps, and achievements of each working group. The experiences and lessons learned from the initiative will be shared during the talk, which we hope will be helpful to the UN as well as developing countries. We will also discuss how to leverage the FOSS4G community and the UN Open GIS Initiative.\n\nNone","original_language":"eng","persons":["Timur Obukhov","HaeKyong Kang","Rick Arias","Maria Brovelli","Ki-Joune Li","Kyoung-Soo Eom"],"tags":["bucharest","161","General"],"view_count":127,"promoted":false,"date":"2019-08-28T00:00:00.000+02:00","release_date":"2019-08-28T02:00:00.000+02:00","updated_at":"2023-06-25T01:00:02.624+02:00","length":1585,"duration":1585,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/161-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/161-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/161-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/161-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-161-the-un-open-gis-initiative-vision-strategies-and-achievements","url":"https://api.media.ccc.de/public/events/bc0ea171-a661-56f9-a518-e32c84bbcf8b","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7463,"event_guid":"b771ce7c-b209-5ad2-a406-de13644ea6de","weight":5},{"event_id":7465,"event_guid":"d2b2bdd0-36fa-5ae1-aba0-a38960010e3b","weight":9},{"event_id":7466,"event_guid":"98c0417b-cdfd-57b3-9411-14f9f465f5b9","weight":6},{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":12},{"event_id":7469,"event_guid":"c0174aef-c7a6-5d21-8dfe-e592c5a4eff3","weight":4},{"event_id":7471,"event_guid":"3c2d5b68-ca8e-5c4e-9110-59ad868cfc70","weight":2},{"event_id":7504,"event_guid":"c54aa667-78de-55fb-85e7-60f2eaffd2a4","weight":4},{"event_id":7518,"event_guid":"8773035b-d16c-5cf3-902d-43abc7e5dab7","weight":3},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":5},{"event_id":7626,"event_guid":"227ae37a-41aa-53d7-944a-2e9b7c8d99a7","weight":4},{"event_id":7629,"event_guid":"43e2163d-d0f7-5b45-945b-25dd8c57118b","weight":3},{"event_id":7652,"event_guid":"e04c27d0-8ff8-5bf4-b932-34db4e4fdf5b","weight":3},{"event_id":7653,"event_guid":"2f97a6f3-e441-505a-8be2-e95554c44430","weight":5}]},{"guid":"7a848633-35e2-5b06-962e-c9cb71cf9762","title":"JuliaGeo: A Fresh Approach to Geospatial Computing","subtitle":null,"slug":"bucharest-428-juliageo-a-fresh-approach-to-geospatial-computing","link":"https://talks.2019.foss4g.org/bucharest/talk/DH8CQR/","description":"2018 saw the release of [Julia](https://julialang.org/) 1.0, a high-level, high-productivity programming language, with the performance of a low-level language like C.

Technologies in Modelling Spatial Accessibility of Primary Health Care in Malawi","subtitle":null,"slug":"bucharest-70-oss-technologies-in-modelling-spatial-accessibility-of-primary-health-care-in-malawi","link":"https://talks.2019.foss4g.org/bucharest/talk/CWT3DA/","description":"Accessibility to primary health care (PHC) in developing countries is crucial and remains a challenge with conflicting statistics in Malawi. For instance, the Health Sector Strategic Plan II, 2017-2022 reports accessibility at 90 % while the Demographic Health Survey puts it at 56 %. The discrepancies emanate from multiple factors among which is failure to incorporate critical geographic cost factors like elevation, road networks, road conditions, etc. in the estimation models. This study, therefore, seeks to develop a PHC accessibility estimation model that incorporates cost spatial factors of elevation and road network distances using open source software and geospatial routing techniques.The accessibility analysis was evaluated using 2 step floating catchment area (2SFCA) model implemented using PostgreSQL/PostGIS and based on the pgr_dijkstraCost algorithm. The model score was expressed in terms of time of travel assuming walking as the mode of travel with a 1-hour threshold indicating acceptable accessibility. To improve accuracy, the road network data was exploded to 20 m node distances. 2SFCA creates two catchment areas called floats in each step.The first step determines the population falling within a specified cost threshold and the facility population ratio. In the second, for each household, the model determines services available within the specified cost threshold at facilities and adds it to the facility population ratio to derive an accessibility score. The 2SFCA score starts from 0 growing boundlessly with 0 indicating households not within the  1-hour threshold. Higher scores indicate access within 1-hour and to multiple facilities or multiple services within an hour or facility respectively.The 2SFCA model result scores ranged from 0 to 0.19, with 100 and 58 % of urban and rural households within 1-hour of a facility (2SFCA \u003e 0) respectively and a district average of 62 %. 70 % of the urban households have access to multiple health facilities (2SFCA \u003e 0.01) as opposed to only 16 % of the rural households. As such the findings provide, arguably, spatially objective PHC accessibility data to inform policy direction and also reveals accessibility to PHC in Malawi to be lower than reported. \nBesides the evaluation of PHC accessibility, the application of FOSS tools in this study, strengthens the case of their relevance in low resource contexts where computation power and electricity can be intermittent, making it difficult to run models that span multiple days. Using PostgreSQL/PostGIS for relational spatial analysis modeling made it possible to resume modelling after power outages. Thus, the study has successfully demonstrated utility of relational spatial analysis using open source technologies in low resource settings of the developing world. With improved computational capabilities such models can be used for national benchmarking of accessibility and hence provide concrete data on the provision of PHC and other applications\n\nNone","original_language":"eng","persons":["Yamikani  Phiri","Kondwani Munthali"],"tags":["bucharest","70","Academic"],"view_count":99,"promoted":false,"date":"2019-08-29T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2025-01-07T18:00:08.316+01:00","length":1819,"duration":1819,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/70-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/70-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/70-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/70-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-70-oss-technologies-in-modelling-spatial-accessibility-of-primary-health-care-in-malawi","url":"https://api.media.ccc.de/public/events/33201832-16d0-59aa-b06b-93d04ed0b637","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7498,"event_guid":"b197164d-0898-54b9-9348-e8d76b0efb91","weight":3},{"event_id":7503,"event_guid":"13ee3371-c9cb-5781-ad63-7e8477ad6b00","weight":1},{"event_id":7509,"event_guid":"2ecaf4b8-9654-58a3-afce-5771d68ac94f","weight":2},{"event_id":7516,"event_guid":"edcad3ee-627e-5a69-8432-c12c4a09173c","weight":2},{"event_id":7528,"event_guid":"92975aff-039a-5545-ba1f-1252a7690110","weight":2},{"event_id":7535,"event_guid":"6f455f9f-a9a4-502e-8e73-b0208dbe8427","weight":1},{"event_id":7571,"event_guid":"ff3f8976-451e-5f00-bc69-fb2dea80b3bb","weight":1},{"event_id":7583,"event_guid":"170c66c2-7991-5555-83b9-28702a52af03","weight":1},{"event_id":7601,"event_guid":"764ef9d5-9a23-5351-ba0c-98e518d7cb50","weight":2},{"event_id":7616,"event_guid":"23bc1246-3fcb-5ce4-ac80-f8c176a25d97","weight":1},{"event_id":7624,"event_guid":"69079f64-448d-55b5-9cb3-7089547c370d","weight":1},{"event_id":7636,"event_guid":"de42794d-e607-5d76-9b1e-3b5e52bd6c68","weight":1},{"event_id":7637,"event_guid":"37fd6d99-fbed-5c0e-b209-5418299ffce5","weight":2},{"event_id":7640,"event_guid":"82b144e3-2fb0-5184-89b7-4594567be536","weight":3},{"event_id":7642,"event_guid":"c51c6100-e015-53bc-8296-486d5e4e3ce7","weight":2},{"event_id":7665,"event_guid":"f1f4f54c-e816-573f-a05d-7973f9f5d48e","weight":1},{"event_id":7681,"event_guid":"a1326956-88be-5af4-b747-5cefc95e8232","weight":1},{"event_id":7683,"event_guid":"6c1f2dfd-1e20-5232-9dc0-f66bdc178f1f","weight":2},{"event_id":7696,"event_guid":"cf0c6d43-7a50-5d88-b6dd-db5aa818aff8","weight":2},{"event_id":7699,"event_guid":"3394a8b8-5954-531f-bbab-877ae065fcee","weight":1},{"event_id":7730,"event_guid":"59c54515-13b2-5d39-9852-266d10f523fd","weight":1},{"event_id":7734,"event_guid":"0e88cd88-aa0a-5920-9708-e22fbf97b784","weight":3},{"event_id":7736,"event_guid":"61205921-df6b-5dff-902b-9d757f719602","weight":3},{"event_id":7737,"event_guid":"a8593987-dcf7-54ec-abef-5fda903cd5a6","weight":2},{"event_id":7738,"event_guid":"ecbd87e4-3c54-5fbe-b5fd-aefc02e7c95d","weight":2},{"event_id":7750,"event_guid":"123bf2f0-6f17-5563-96c7-430cfe28dd0d","weight":2},{"event_id":7752,"event_guid":"78ceca87-11cf-598f-9ad3-100d9652a2b4","weight":1}]},{"guid":"1dac21fe-e493-541b-8e5f-ba1c1f15db2c","title":"Open data in health-geomatics: mapping and evaluating publicly accessible defibrillators","subtitle":null,"slug":"bucharest-73-open-data-in-health-geomatics-mapping-and-evaluating-publicly-accessible-defibrillators","link":"https://talks.2019.foss4g.org/bucharest/talk/KQNMDG/","description":"Geomatics is the key resource in analyzing the deployment of publicly accessible Automated External Defibrillators (AED). Since AEDs are only effective if used within 6 minutes from the onset of an Out-of-Hospital Cardiac Arrest (OHCA), they have a limited area of effectiveness (i.e. ‘catchment area’, CA), that is traditionally computed as a circular surface with radius = 100m. The availability of open geospatial data related to roads network and edification on the territory allows to compute realistic catchment areas based on the effective distance along streets, which is a novel approach, never compared with the traditional method.\nAim of this study was to compare the two approaches, and to evaluate if the territory analysis could support decision making about the mapping technique better suiting each device. The study was performed and validated on the territory of Lombardy (Italy, total surface 23’863.65 km2), and CAs were computed for 7458 known AEDs on the territory (at 28/02/2018). The analysis was performed exploiting open source software, specifically QGIS and PostGIS with pgRouting extension. \nSetting a limit of 200m for the realistic CAs, their mean surface for the considered dataset resulted close to that of the traditional circular area: 33’665 m2 against 31’416 m2. However, the spatial coverage of OHCAs (events occurring inside a CA, on the base of a georeferenced database of 45039 OHCAs occurred in Lombardy within 1/1/2015 and 31/12/2018) estimated considering circular areas (9.43%) is very different from that obtained considering realistic areas (15.35%).\nThe distribution of the mapping error (surface of realistic CA – surface of circular CA) was studied, and its correlation with the characteristics of the surrounding territory was inspected. The considered attributes were: I) distance from the device to the nearest road; II) total length of the roads in the surrounding area; III) number of roads network nodes in the surrounding area; IV) percentage of edified surface in the surrounding area; surrounding area for II) to IV) was a circular area of 50, 100, 150, 200 and 250 m radius. The most correlated attributes were: I) R = -0.58 (p\u003c0.05), and II) R = 0.65 (p\u003c0.05) in 50m-radius area.\nResults suggest that circular CAs underestimate the spatial coverage of AEDs located nearby streets in a densely networked area, and in these cases realistic CAs, better suiting real-world scenario, are preferable. However, when AEDs are far from the streets, realistic mapping is not reliable, and the use of circular areas is preferable. This second situation is typical of large and isolated facilities (e.g. airports, sport facilities, warehouses), and the circular area better estimates the coverage of the facility itself.\nWith known AEDs location, open data and open source software are reliable enough to decide which mapping technique will result in a better estimation of the

of the Global Land Cover Maps in Africa Suplemented by Spatial Association of Errors","subtitle":null,"slug":"bucharest-90-inter-comparison-of-the-global-land-cover-maps-in-africa-suplemented-by-spatial-association-of-errors","link":"https://talks.2019.foss4g.org/bucharest/talk/YJ8KJS/","description":"During the last decades, production of Land Cover maps (LC) at a continental and global scale has increased thanks to the progress in Earth Observation capacities, as well as due to high demand for these maps for many applications (e.g. climate change monitoring). However, the usefulness of these maps strongly depends on their accuracy. Therefore, for a fruitful LC maps exploitation, accuracy assessments (i.e. validation and inter-comparison) must antedate. Spatial analysis of the errors should then complement the accuracy assessment to provide insights into the local errors patterns which may not be outlined by traditional accuracy assessment techniques.\nAccording to this, we propose here a comprehensive analysis to target accuracy of LCs by focusing on the African continent. Two datasets, GlobeLand30 (GLC30) at and CCI Land Cover - S2 Prototype Land Cover 20m Map Of Africa (CCI Prototype Africa), at 30m and 20m resolution respectively, were considered.\n\nInter-comparison was performed by means of traditional accuracy indexes computed from the error matrix (i.e. Overall Accuracy, Producer’s and User’s accuracy etc). Harmonization of the two maps in terms of resolution and classification nomenclature is prerequisite for inter-comparison. This was achieved by taking advantage of QGIS functionalities (e.g. resampling). Results of the accuracy assessment provide overall quality metrics for the map as well as quality indicators for each LC class.\n\nAdditionally, spatial association statistics were adopted to investigate local patterns of the errors.  The analysis was performed by means of GRASS  and custom developed Python scripts exploiting cutting-edge data analysis libraries such as Pandas, Dask, and PySAL. By “virtual” overlaying CCI with GLC30, we computed which classes of CCI are under each pixel of GLC30, and what is the pixel fraction of a CCI class at each GLC30 pixel. Results of the overlay were stored in a vector point file whose coordinates represent centers of pixels of GLC30. If the classes of GLC30 and CCI for a point are not the same this results in an error with magnitude represented by the pixel fraction itself. Error fractions at each GLC30 pixel were analysed by means of Local Indicators of Spatial Association (LISA) to map non-random pattern in the spatial distribution of the errors as well as to assess their intensity and spatial association typology. \n\nBy considering the results of accuracy assessment and LISA outputs, a comprehensive comparison of the GLC30 or CCI Prototype Africa is achieved. The results provide a guideline for detecting source of the error, which is potentially useful for future LC production (i.e. sampling design of training data). Lastly, it has been demonstrated that processing of massive datasets for accuracy assessment can be accomplished with Free and Open Source Software (FOSS).\n\nNone","original_language":"eng","persons":["Maria Brovelli","Daniele Oxoli","Gorica Bratic"],"tags":["bucharest","90","2019","Academic"],"view_count":40,"promoted":false,"date":"2019-08-28T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2022-12-25T08:45:02.329+01:00","length":1313,"duration":1313,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/90-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/90-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/90-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/90-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-90-inter-comparison-of-the-global-land-cover-maps-in-africa-suplemented-by-spatial-association-of-errors","url":"https://api.media.ccc.de/public/events/cdcc0bac-ebad-566c-b691-c54010212a86","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7472,"event_guid":"d021f555-141a-58f6-a21b-a787b1c84188","weight":2},{"event_id":7475,"event_guid":"49a7c19c-a42e-5058-afe1-7577dd2736c9","weight":1},{"event_id":7501,"event_guid":"a4aa4222-f2ca-5e0c-94f6-4c7a3595d1a2","weight":2},{"event_id":7505,"event_guid":"5ac07c14-e2f1-5cba-a86f-047443848af5","weight":1},{"event_id":7519,"event_guid":"33229e10-d954-564b-bb6f-f48e5b5d3882","weight":1},{"event_id":7524,"event_guid":"f58c39cb-2250-51b5-8902-d52f713c934b","weight":1},{"event_id":7533,"event_guid":"bff8e480-f2e6-5fb7-a945-fed5e6b06f77","weight":1},{"event_id":7539,"event_guid":"deadde12-6ce3-5394-aeec-531251a711a2","weight":1},{"event_id":7553,"event_guid":"9f0999f8-6941-5308-b1a8-f094c738245f","weight":1},{"event_id":7556,"event_guid":"c9b9934c-1cec-518c-ab2f-6a70ee5622f0","weight":1},{"event_id":7583,"event_guid":"170c66c2-7991-5555-83b9-28702a52af03","weight":1},{"event_id":7640,"event_guid":"82b144e3-2fb0-5184-89b7-4594567be536","weight":2},{"event_id":7641,"event_guid":"d5b00dcc-d898-5a3a-bc8f-8e62d492bf4e","weight":1},{"event_id":7646,"event_guid":"1e986309-98ba-5840-b70e-300ff54d78bc","weight":1},{"event_id":7651,"event_guid":"84c94e48-3002-55f3-9d4a-c66f5d2e4198","weight":1},{"event_id":7655,"event_guid":"3b5c1185-42c2-5e87-b4ba-779be1a3297b","weight":2},{"event_id":7676,"event_guid":"d77d9253-da6c-521a-ad5e-ff17c419cbea","weight":1},{"event_id":7704,"event_guid":"d4397024-b341-5a6f-ab92-b0f157931833","weight":1},{"event_id":7724,"event_guid":"583daa21-2358-57db-8ee9-d7e1572e4c8f","weight":1},{"event_id":7735,"event_guid":"87cfd947-401b-57a9-9ea2-4f6a76b8fdd6","weight":2},{"event_id":7746,"event_guid":"d6b3b1a7-ed40-50da-a4ef-43775cad7688","weight":1}]},{"guid":"6cef82f8-4f16-5fcd-adf6-aae52595dcfa","title":"Extracting cloud free images in an area of interest from a remote sensing archive","subtitle":null,"slug":"bucharest-179-extracting-cloud-free-images-in-an-area-of-interest-from-a-remote-sensing-archive","link":"https://talks.2019.foss4g.org/bucharest/talk/RQFEJA/","description":"Open source satellite imagery becomes increasingly important in many areas of research and business. In the case of agriculture, it is being used to assess land use, support subsidies, and to help farmers to manage their land more efficiently. Many of these applications require regular revisits to best catch temporal the variety that defines many land uses. \nCloud cover can be a serious issue, often obscuring the majority of images acquired from passive sensors. Filtering an area of interest for cloud free images, can be labour intensive or lead to loss of valuable input data.\nHere we introduce a Python tool developed using open-source packages that will assess user defined areas of interest against supplied cloud masks for three satellite platforms: ESA’s Sentinel-2 (Level 1C products), NASA’s Landsat-8 (Level 1C and SR products) and the joint CNES and ISA platform Venµs.\nWe present a case study from County Meath, Ireland to assess the number of cloud free Sentinel-2 images identified for fields surveyed in the EU Land Use/Cover Area Frame Survey (LUCAS) and compare it to the number of images that would have been obtained by threshold filtering images.\n\nNone","original_language":"eng","persons":["Jesko Zimmermann"],"tags":["bucharest","179","2019","General"],"view_count":54,"promoted":false,"date":"2019-08-30T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2023-12-28T04:30:02.745+01:00","length":1242,"duration":1242,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/179-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/179-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/179-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/179-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-179-extracting-cloud-free-images-in-an-area-of-interest-from-a-remote-sensing-archive","url":"https://api.media.ccc.de/public/events/6cef82f8-4f16-5fcd-adf6-aae52595dcfa","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7465,"event_guid":"d2b2bdd0-36fa-5ae1-aba0-a38960010e3b","weight":2},{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":4},{"event_id":7475,"event_guid":"49a7c19c-a42e-5058-afe1-7577dd2736c9","weight":2},{"event_id":7477,"event_guid":"9227fcf3-b7b2-5a7a-b135-3e7a18341a82","weight":1},{"event_id":7483,"event_guid":"54f0806e-4257-53c6-a558-e336ee584bb5","weight":2},{"event_id":7484,"event_guid":"b4d6c8c6-688b-5273-aa8f-a2044128ac13","weight":2},{"event_id":7488,"event_guid":"0a3e23aa-d593-58cd-a3a1-7991e3a3a064","weight":2},{"event_id":7489,"event_guid":"7c66788d-24a7-5951-865f-c85816356441","weight":2},{"event_id":7495,"event_guid":"bffc8bd9-0df8-5543-8c24-254c05092bbd","weight":1},{"event_id":7504,"event_guid":"c54aa667-78de-55fb-85e7-60f2eaffd2a4","weight":3},{"event_id":7505,"event_guid":"5ac07c14-e2f1-5cba-a86f-047443848af5","weight":3},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":2},{"event_id":7552,"event_guid":"4c2f4b81-1316-502d-870c-dc39567b782e","weight":3},{"event_id":7553,"event_guid":"9f0999f8-6941-5308-b1a8-f094c738245f","weight":1},{"event_id":7572,"event_guid":"fb951433-b271-5884-b370-a8ef56393406","weight":3},{"event_id":7584,"event_guid":"41e880ab-ca8a-5a40-aeeb-4b75fb3a94d3","weight":4},{"event_id":7591,"event_guid":"3a4e2ca2-c4f2-5516-8f69-01be68113f22","weight":1},{"event_id":7623,"event_guid":"d7305220-5dac-5581-bf1b-14e735c39756","weight":2},{"event_id":7624,"event_guid":"69079f64-448d-55b5-9cb3-7089547c370d","weight":1},{"event_id":7633,"event_guid":"a8aaa8da-f9ee-53ef-958c-ff6f326b3f81","weight":1},{"event_id":7635,"event_guid":"a134c0ce-1291-54b1-a56e-547284a962f0","weight":2},{"event_id":7648,"event_guid":"82181807-6c4a-560f-a34d-116d440a540b","weight":2},{"event_id":7652,"event_guid":"e04c27d0-8ff8-5bf4-b932-34db4e4fdf5b","weight":2},{"event_id":7665,"event_guid":"f1f4f54c-e816-573f-a05d-7973f9f5d48e","weight":2},{"event_id":7673,"event_guid":"89f564bf-e743-5086-a372-478a49b0d7ce","weight":2},{"event_id":7678,"event_guid":"c9058144-0344-5cdd-9e8d-228d9a6443f3","weight":1},{"event_id":7695,"event_guid":"5df0ebe1-cfe2-54c4-a0c8-40e35a6de826","weight":1},{"event_id":7709,"event_guid":"936a0a3d-27d2-5bb7-a59a-336837047e72","weight":1},{"event_id":7713,"event_guid":"14dfde19-5a7a-59ee-8470-e75266353678","weight":3},{"event_id":7721,"event_guid":"9462ccbb-1601-5d12-8756-5e11e3134112","weight":2},{"event_id":7726,"event_guid":"5fabfcb3-0d99-553b-a6f8-5a6119513afc","weight":2},{"event_id":7732,"event_guid":"771fc01c-25ee-5202-abbe-0b993a5e7ace","weight":1},{"event_id":7737,"event_guid":"a8593987-dcf7-54ec-abef-5fda903cd5a6","weight":1},{"event_id":7739,"event_guid":"9fb4a987-3f98-530a-9177-41099f13ddef","weight":2},{"event_id":7746,"event_guid":"d6b3b1a7-ed40-50da-a4ef-43775cad7688","weight":1}]},{"guid":"dd3327f8-7f66-5844-bc78-9dede7aeb710","title":"EO Data Challenge proposals","subtitle":null,"slug":"bucharest-513-eo-data-challenge-proposals","link":"https://talks.2019.foss4g.org/bucharest/talk/K7ADDK/","description":"During this 90 minutes slot, the results obtained by the teams at EO Data Challenge will shortly present their results.

development, from its wide range of shortest path search algorithms and other algorithms like driving distance calculation or “Traveling Sales Person” (TSP) optimization, graph contraction, flow analysis etc. Additionally we will give a brief outlook and introduction of upcoming new features on the version 3.0.\n\nWe will explain how the data structure is important to get better routing results. Furthermore we will show how you can improve the quality of the search with dynamic costs and make the result look closer to the reality. You will also learn about difficulties and limitations of the library, and when pgRouting might not be not the right tool to solve your routing problem.\n\nLinks to project:

worked with geospatial technology in the insurance industry since 2003 I had my eyes opened to open source at FOSS4G 2013 in Nottingham.  I came away excited and energised by what I had seen and it planted the idea for how we could do things differently.  2 years later I quit my day job as a contract solutions architect and took a big pay cut to create Addresscloud, our aim to tackle the complex geocoding challenges faced by UK/I insurers.  3 years on we have gone from strength to strength and are now a profitable, rapidly growing business with a portfolio of customers from startups to FTSE 100 companies.  In this talk I will discuss our journey, challenges along the way and our lessons learned.\n\nNone","original_language":"eng","persons":["Mark

Nevertheless in-situ monitoring is essential for a large number of actions that requires continuous, long-term, high-frequency, and accurate data as well as to calibrate and validate remote sensing data. With the advent of IoT in situ monitoring is getting back the necessary attention and more people, also in the field of FOSS4G, are starting to work in this field.\nThe IstSOS development team is working since the 2009 to bring in-situ monitoring back to the golden ages fostering the interoperability and the data management best practices. Several projects are here presented to demonstrate how istSOS, IoT and openness can contribute to this goal through a number of applications in the fields of agriculture (ENORASIS), water management (hydromMetTI, FREEWAT, TRESA), risk mitigation (SITGAP, MIARIA), health (ALBIS), development and cooperation (4ONSE).\n\nNone","original_language":"eng","persons":["Daniele Strigaro","Milan","Massimiliano Cannata"],"tags":["bucharest","366","2019","General"],"view_count":48,"promoted":false,"date":"2019-08-29T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2025-05-03T10:00:04.775+02:00","length":1542,"duration":1542,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/366-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/366-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/366-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/366-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-366-in-situ-observation-renaissance-with-istsos-and-iot","url":"https://api.media.ccc.de/public/events/d265363a-2529-5055-80ad-05459b56a581","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":1},{"event_id":7469,"event_guid":"c0174aef-c7a6-5d21-8dfe-e592c5a4eff3","weight":2},{"event_id":7501,"event_guid":"a4aa4222-f2ca-5e0c-94f6-4c7a3595d1a2","weight":3},{"event_id":7504,"event_guid":"c54aa667-78de-55fb-85e7-60f2eaffd2a4","weight":3},{"event_id":7505,"event_guid":"5ac07c14-e2f1-5cba-a86f-047443848af5","weight":2},{"event_id":7517,"event_guid":"ef1a3ce2-61bf-53e1-8f97-acb738c219f9","weight":1},{"event_id":7523,"event_guid":"a95cf31f-07d2-5255-bfa2-6fb38923a15f","weight":2},{"event_id":7530,"event_guid":"27739ac4-67df-54da-a0f4-633bc7a9ac61","weight":1},{"event_id":7533,"event_guid":"bff8e480-f2e6-5fb7-a945-fed5e6b06f77","weight":1},{"event_id":7534,"event_guid":"3fc26cc4-962e-5f27-a92b-c01e86d12100","weight":1},{"event_id":7545,"event_guid":"726938bf-af52-5c0e-9198-0053eba64726","weight":1},{"event_id":7548,"event_guid":"8ca1b4b6-ee0c-5102-ab95-a978cd3b4d8c","weight":2},{"event_id":7554,"event_guid":"20bb70f9-e0ab-5d46-9e99-71cd75e04251","weight":1},{"event_id":7579,"event_guid":"0112454d-62b2-5132-8971-73c7fdb972d0","weight":1},{"event_id":7580,"event_guid":"c068c48a-bbac-5dda-bb74-e1e56672cc12","weight":1},{"event_id":7585,"event_guid":"3e149633-f405-5e9b-850c-b0934537b6d8","weight":1},{"event_id":7593,"event_guid":"6a8c04d0-d372-5f16-87a2-96f537854ebc","weight":2},{"event_id":7594,"event_guid":"9f3b41cc-dc93-55d8-a318-7b7740109b71","weight":2},{"event_id":7595,"event_guid":"1b45aaaa-70dc-5f27-8b7b-64dc0fe409a5","weight":4},{"event_id":7604,"event_guid":"b0001b70-6e5d-50e1-aaa4-51345e1d7a65","weight":2},{"event_id":7607,"event_guid":"d0794cae-d707-584c-8879-6c438a603486","weight":3},{"event_id":7617,"event_guid":"5eaf093f-4b8d-5455-9a6c-252d78a94e9c","weight":1},{"event_id":7634,"event_guid":"09fd4e88-d4b2-524b-aecf-da9a0bed1c71","weight":1},{"event_id":7648,"event_guid":"82181807-6c4a-560f-a34d-116d440a540b","weight":2},{"event_id":7660,"event_guid":"17585226-58b0-51da-a3b6-3c41ff51db2c","weight":2},{"event_id":7664,"event_guid":"bc480eaa-8db8-54d0-bc53-32a81725f2d9","weight":1},{"event_id":7667,"event_guid":"4bc8bbe5-cb04-5a2b-b441-a696be055948","weight":1},{"event_id":7672,"event_guid":"1c58bd3e-15f6-51a3-af44-9d6a75f31556","weight":1},{"event_id":7691,"event_guid":"51a27fc2-ea89-5b31-8a60-fed8cdc9ef91","weight":2},{"event_id":7692,"event_guid":"3c0ea464-ce0e-5676-a977-075148d7bbdd","weight":2},{"event_id":7695,"event_guid":"5df0ebe1-cfe2-54c4-a0c8-40e35a6de826","weight":1},{"event_id":7710,"event_guid":"9bce8e1a-0dc8-5c82-977c-23dccd115e89","weight":1},{"event_id":7713,"event_guid":"14dfde19-5a7a-59ee-8470-e75266353678","weight":2},{"event_id":7725,"event_guid":"63a63204-d0dd-57d5-aae3-d766a3be9d23","weight":1},{"event_id":7733,"event_guid":"0ba5c644-2353-5225-972e-6e3958f74f3e","weight":1},{"event_id":7736,"event_guid":"61205921-df6b-5dff-902b-9d757f719602","weight":1},{"event_id":7738,"event_guid":"ecbd87e4-3c54-5fbe-b5fd-aefc02e7c95d","weight":1},{"event_id":7758,"event_guid":"d7541c86-83fd-55c3-8843-f64e30b8aa55","weight":1}]},{"guid":"4ae662a0-789b-56b6-a357-ed2384226e9d","title":"Spatial Support in MySQL","subtitle":null,"slug":"bucharest-132-spatial-support-in-mysql","link":"https://talks.2019.foss4g.org/bucharest/talk/7TF7ZW/","description":"MySQL 8.0 was a huge step in terms of spatial support -- a step up from flat Cartesian coordinate systems to ellipsoidal geography.

(https://github.com/ungarj/mapchete) is a tool written in Python which helps processing large amounts of geodata such as global high resolution datasets. It does so by executing a user-defined Python function on smaller chunks of data (tiles).\n\nThe standard tiling schemes follow the well-known tile pyramid schemes used by WMTS which also enable mapchete to let the user easily preview process outputs using a built-in development server (Flask) hosting an OpenLayers page.\n\nBy processing large areas through their much smaller tiles or metatiles, possible memory errors can be avoided. Furthermore, tiles can be processed on multiple CPU cores in parallel which speeds up the processing time.\n\nAll geospatial data (i.e. raster and feature data) are internally handled and exposed to the user-defined process function either as NumPy arrays (raster) or GeoJSON-like dictionaries (features) which can easily be edited with well-known Python packages like shapely or scipy.\n\nFor I/O operations mapchete makes heavy use of rasterio (https://github.com/mapbox/rasterio) and Fiona (https://github.com/Toblerity/Fiona).

An electronic navigational chart or ENC (IENC for Inland waterways) is an official database created by a national hydrographic office for use with an Electronic Chart Display and Information System (ECDIS). \nThe automatic identification system (AIS) is an automatic tracking system that uses transponders on ships and is used by vessel traffic services (VTS).\nEven with the advent of high accuray DGPS and AIS, RADAR will continue to be a primary aid to navigation and collision avoidance.\nDuring the presentation we will exemplify some usecases that integrate ENC, AIS and RADAR data in various software applications, both web and desktop, onboard for navigation or vessel/infrastructure for coastal monitoring systems.\nThe presentation will cover an aids for navigation monitoring system, a vessel traffic management system and an 3D environment with real time data for validation of inland waterway signs and markings.\n\nNone","original_language":"eng","persons":["Bogdan Grama","Unnamed user"],"tags":["bucharest","162","General"],"view_count":98,"promoted":false,"date":"2019-08-28T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2025-05-08T22:15:08.689+02:00","length":1491,"duration":1491,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/162-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/162-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/162-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/162-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-162-safer-navigation-using-electronic-navigational-charts-ais-and-radar-data-powered-by-foss4g","url":"https://api.media.ccc.de/public/events/d77d9253-da6c-521a-ad5e-ff17c419cbea","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7473,"event_guid":"feda735f-5467-56f0-9ddf-55cefdf60199","weight":1},{"event_id":7475,"event_guid":"49a7c19c-a42e-5058-afe1-7577dd2736c9","weight":2},{"event_id":7487,"event_guid":"6f1b8b15-b44a-592c-b3e9-96bd9e0fbce3","weight":2},{"event_id":7488,"event_guid":"0a3e23aa-d593-58cd-a3a1-7991e3a3a064","weight":2},{"event_id":7490,"event_guid":"8b42d166-f7a0-5cc0-a66d-5717fc99b6d0","weight":2},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":1},{"event_id":7523,"event_guid":"a95cf31f-07d2-5255-bfa2-6fb38923a15f","weight":1},{"event_id":7556,"event_guid":"c9b9934c-1cec-518c-ab2f-6a70ee5622f0","weight":3},{"event_id":7572,"event_guid":"fb951433-b271-5884-b370-a8ef56393406","weight":1},{"event_id":7577,"event_guid":"2b9d3727-6fec-552b-99b1-f240c64986b4","weight":1},{"event_id":7613,"event_guid":"0b7d0b85-cf67-5382-aba4-9035a9e7963a","weight":1},{"event_id":7624,"event_guid":"69079f64-448d-55b5-9cb3-7089547c370d","weight":1},{"event_id":7629,"event_guid":"43e2163d-d0f7-5b45-945b-25dd8c57118b","weight":1},{"event_id":7662,"event_guid":"a8fbf537-cbe1-5f17-aa73-97d64132f660","weight":1},{"event_id":7691,"event_guid":"51a27fc2-ea89-5b31-8a60-fed8cdc9ef91","weight":1},{"event_id":7706,"event_guid":"2931c54a-5a66-5024-87ea-4c283dc0f8f2","weight":1},{"event_id":7725,"event_guid":"63a63204-d0dd-57d5-aae3-d766a3be9d23","weight":1},{"event_id":7757,"event_guid":"08e7e90e-7da4-524d-8875-b38d23b6c1cf","weight":1}]},{"guid":"d021f555-141a-58f6-a21b-a787b1c84188","title":"Show me the good grass: an open GIS powered call center for livestock herders in Mali.","subtitle":null,"slug":"bucharest-124-show-me-the-good-grass-an-open-gis-powered-call-center-for-livestock-herders-in-mali-","link":"https://talks.2019.foss4g.org/bucharest/talk/YFSS9V/","description":"A call center powered by an open GIS platform helps livestock herders in Northern Mali find pasture and water through the \"Sustainable Technology Adaptation for Malian Pastoralists\" (STAMP) programme.

for performance \n\nThe MapServer software offers many powerful and advanced features that many users haven’t found yet.  Come and learn some of the tricks to optimize configurations to achieve excellent performance in the rendering of stunning cartographic maps.  Complex road shield labeling is one of the use cases that will be shared. Many of the tricks are based on advanced preprocessing of the data sources using the GDAL/OGR tools.  Another subject will be around different ways to use tile indexes and how that can influence flexibility and performance.  Some advanced line symbology examples will be highlighted, that are used in a larger open source development with Mapserver.  Finally, we will show how to measure and even set up automatic tests to verify the results. The presenter is a frequent Mapserver user.\n\nNone","original_language":"eng","persons":["Lars

In our mission statement we aim to \"create a networked community of OSGeo/FOSS4G users, developers, practitioners, teachers, advocates, etc in Ireland\". Our talk will discuss experiences since 2015:  Developing a shared understanding of community participation in OSGeoIE events, how to be effectively resourced as a local community, attempts to establish a more coordinated approach to communication and learning between partnerships, governmental agencies, industry and other software communities and how participation in OSGeoIE make a difference for volunteers and OSGeo/FOSS4G users and advocates? There is increasing cross discipline/domain interest in QGIS with particular interest in QGIS from local government authorities.

Since 2012 we have been working hard in order to evangelize about free and open source software. Drawing inspiration, and a name, from the Geoinquietos Spain micro chapter a few people started gathering (beer in between) to spread the word about free tools for geomatics. Since then, we have been able to do four conferences, some together with the OpenStreetMap (OSM) community. Recently we became an official OSGEO local chapter (the first constituted in Latin America). In order to keep growing, we have set up an nonprofit organization (Geolibres), to serve as a legal support not only for Geoinquiet@s, but also for OSM Argentina or GeochicasOSM. We propose the bid of Buenos Aires as the location for the 2021 main FOSS4G event, because we believe it would be a great opportunity for the entire region, creating new chances for exchange between key actors in the world of free and open geomatics. Our commitment is for more conferences, workshops and other projects that infect the spirit of free and open source software in more people, communities, companies, organizations and universities every time.\n\nNone","original_language":"eng","persons":["Malena Libman","Andrea Trovant","Ariel Anthieni"],"tags":["bucharest","154","2019","General"],"view_count":27,"promoted":false,"date":"2019-08-30T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2023-10-30T10:30:03.215+01:00","length":519,"duration":519,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/154-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/154-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/154-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/154-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-154-the-foss4g-path-in-argentina","url":"https://api.media.ccc.de/public/events/8ef7bba2-4df3-5bf0-9208-b8f5badad5eb","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7471,"event_guid":"3c2d5b68-ca8e-5c4e-9110-59ad868cfc70","weight":1},{"event_id":7475,"event_guid":"49a7c19c-a42e-5058-afe1-7577dd2736c9","weight":1},{"event_id":7476,"event_guid":"27f015cf-fe4e-55b2-bdb7-01a850ca00af","weight":1},{"event_id":7479,"event_guid":"5cb82c9e-bc84-54e2-a40d-60b78f35ef46","weight":1},{"event_id":7480,"event_guid":"603a5649-724a-53d7-ac20-ff7d520696d3","weight":1},{"event_id":7488,"event_guid":"0a3e23aa-d593-58cd-a3a1-7991e3a3a064","weight":1},{"event_id":7499,"event_guid":"de560d64-70a3-518c-b12d-5b639a1c7b97","weight":3},{"event_id":7502,"event_guid":"22e35ec7-d84e-5a95-a490-adc14715792b","weight":1},{"event_id":7514,"event_guid":"0d63b0b4-259d-5114-8c8f-18604b514f7d","weight":1},{"event_id":7518,"event_guid":"8773035b-d16c-5cf3-902d-43abc7e5dab7","weight":1},{"event_id":7528,"event_guid":"92975aff-039a-5545-ba1f-1252a7690110","weight":1},{"event_id":7536,"event_guid":"9f921eab-53c5-5ce7-9489-45a586162248","weight":1},{"event_id":7538,"event_guid":"18d0bdd8-5bdf-536e-9a51-5479ba1be544","weight":1},{"event_id":7552,"event_guid":"4c2f4b81-1316-502d-870c-dc39567b782e","weight":1},{"event_id":7578,"event_guid":"d5d6bac8-cb8a-504a-9a3f-ced5c377e1bd","weight":1},{"event_id":7579,"event_guid":"0112454d-62b2-5132-8971-73c7fdb972d0","weight":1},{"event_id":7587,"event_guid":"1dac21fe-e493-541b-8e5f-ba1c1f15db2c","weight":1},{"event_id":7607,"event_guid":"d0794cae-d707-584c-8879-6c438a603486","weight":1},{"event_id":7667,"event_guid":"4bc8bbe5-cb04-5a2b-b441-a696be055948","weight":1},{"event_id":7677,"event_guid":"9ba1e879-6d50-5e4b-b3a1-5267a000b2ed","weight":1},{"event_id":7700,"event_guid":"a45f513c-23e0-512d-a69c-8163e5edf0d8","weight":1},{"event_id":7707,"event_guid":"8f9b67d8-fd60-522f-9a5b-6f0f81626e5c","weight":1},{"event_id":7710,"event_guid":"9bce8e1a-0dc8-5c82-977c-23dccd115e89","weight":1},{"event_id":7716,"event_guid":"551ebb23-42b6-59a8-a1e2-1050151985d3","weight":1},{"event_id":7727,"event_guid":"812560ad-8181-524d-a843-95523fed1e81","weight":1},{"event_id":7729,"event_guid":"9d030aa8-27aa-509b-913f-ee9eff97257b","weight":1},{"event_id":7732,"event_guid":"771fc01c-25ee-5202-abbe-0b993a5e7ace","weight":1},{"event_id":7737,"event_guid":"a8593987-dcf7-54ec-abef-5fda903cd5a6","weight":1},{"event_id":7740,"event_guid":"503efde4-1e72-51f5-b508-4ca91a364086","weight":1},{"event_id":7749,"event_guid":"5117b85e-052d-5b96-bcc3-f14e953b887a","weight":1}]},{"guid":"835f3234-2e2a-5d75-a3f3-7c822e225d60","title":"Let's Power the Analytics and 3D to the Web Based Military Geo-Portal using FOSS4G!","subtitle":null,"slug":"bucharest-192-let-s-power-the-analytics-and-3d-to-the-web-based-military-geo-portal-using-foss4g-","link":"https://talks.2019.foss4g.org/bucharest/talk/Z3VSSA/","description":"I'll introduce the web based military geo-portal system which was implemented on top of numerous open source projects such as PostGIS, GeoServer, Cesium, mago3D, OpenGXT.

Maps served by\nQGIS Server are designed in QGIS Desktop, and rendered by QGIS Server with the same rendering engine as QGIS Desktop.  This makes it possible to leverage QGIS advanced styling capabilities, which, in itself, is a major advantage over its competitors.\n\nThe QGIS community is serious at making QGIS Server production-grade.  QGIS Server is now certified by the OGC, and CI processes have been set up for continuously assessing its OGC compliancy and performance.\n\nIn production context an important aspect is the way QGIS Server is executed.  There are many ways to execute QGIS Server.  QGIS Server may be controlled by the Apache HTTP Server, or it may be run as an independent process in front of the NGINX HTTP Server.  Some people use Docker, while others rely on more traditional systems.  The way QGIS Server is executed and configured can have a major impact on the performance and robustness.\n\nAfter a quick introduction to QGIS Server this talk dives into the various ways of executing QGIS Server in production, discussing the pros and cons of each method.

technologies are often at odds with each other for historical reasons. GIS software has developed in niches, predominantly through monolithic and proprietary systems. The growing need to expose geodata on the web, e.g. sparked through open data policies, leaves developers with a range of options. Clients may request server-side solutions such as OGC services such as Web Map Service, Web Feature Service and the likes. These solutions require a map server. Another option for instance is a direct database query that requests relational data through PHP. Since almost all big database management systems are spatially enabled today (Oracle Spatial, MS SQL Server, PostgreSQL/PostGIS, MySQL) there is per se no need to implement a map server at all. A third option is to use web clients’ native data formats such as JSON/GEOJSON. This may either be requested by a REST API, a JSON-capable DB (e.g. MongoDB) or through flat files. Which of these options serves my purposes best?

Though field mapping is a reliable method, this may become\ninfeasible for large basins. High resolution remote sensing data provides another way to\npredict channel heads. Existing literatures have suggested use of digital elevation models\n(DEM) to extract channel heads by applying an area or slope-area thresholding method.\nHowever, channel initiation process is more complex and depends on other factors like\ntopographic curvature, land use land cover etc. In this study, we have used machine learning\nmodels to extract channel heads from freely available 1 arc second SRTM DEM data for a\nbasin in the Lesser Himalaya. We have used upstream area, local slope and local curvature as\nfeatures in our models. Actual channel heads were digitized manually from high-resolution\n(1-2 m) IKONOS imagery available on Google Earth. Decision tree model generated the best\nresults with a F1-score of 0.45 and correctly predicted around 78% of the channel heads from\nthe test set along with a high number of false positives.

this paper, we address the course of dimensionality and scalability issues while managing vast volumes of multidimensional raster data in the renewable energy modeling process in an appropriate spatial and temporal context. Tensor representation provides a convenient way to capture inter-dependencies along multiple dimensions. In this direction, we propose a sophisticated approach of handling large-scale multi-layered spatio-temporal data, adopted for raster-based geographic information systems (GIS). Moreover, it can serve as an extension of map algebra to multiple dimensions for spatio-temporal data processing. We use the multidimensional tensor framework to model such problems and apply computational graphs for efficient execution of calculation processes. In this approach, spatio-temporal data can be represented as non-overlapping, regular tiles of 2-D raster data, stacked according to the time of data captured. As a case study, we quantify the spatio-temporal dynamics of solar irradiation calculations and 2.5-D shadow calculations for cities at very high space-time resolution using the proposed framework. For that, we chose Tensorflow, an open source software library developed by Google using data flow graphs and the tensor data structure. We provide a comprehensive performance evaluation of the proposed model against r.sun based on GRASS GIS. Benchmarking shows that the tensor-based approach outperforms r.sun by up to 60%, concerning overall execution time for high-resolution datasets and fine-grained time intervals for daily sums of solar irradiation [Wh.m-2.day-1]. Precisely, the main characteristics of the proposed framework include defining, optimizing and efficiently calculating mathematical expressions involving multi-dimensional arrays (tensors); Transparent use of GPU computing such that the same code can be run either on CPUs or GPUs; Implicit parallelism and distributed execution with high scalability offered by data-flow based implementation.

the past, desktop GIS were necessary to handle complex spatial business decisions. This lead to problems with data management, model updates and an increased cost to the organisation in hardware and (often) software maintenance. As organisations move to more cloud based solutions and provide staff with thinner client machines (chrome books etc.) it becomes harder for staff to manage more complex geospatial problems. \n\nThe Open Geospatial Consortium (OGC) developed the web processing service (WPS) standard in 2005. It provides rules for standardizing how inputs and outputs (requests and responses) for geospatial processing services are made. The standard also defines how a client can request the execution of a process, and how the output from the process is handled. It defines an interface that facilitates the publishing of geospatial processes and clients’ discovery of and binding to those processes.\n\nThis talk will present case studies of how Astun Technology has used the OGC WPS standard, as implemented by GeoServer, to allow users of web based mapping applications to carry out advanced spatial operations and allowed them to implement complex business logic without the need for specialised hardware or software.\n\nNone","original_language":"eng","persons":["Ian

this keynote, we’ll explore the explosive growth in quantity of geospatial data, and how this is fueling the need to more frequently join geospatial data with traditional data. We’ll explain how those new scale requirements demand a massive improvement in speed, and how GPUs can be used to accelerate the querying of geospatial data using an open source in-GPU-memory SQL database. Finally, we will demonstrate interactive analysis of the entire, global Open Street Map dataset as an example of what is now possible.\n\nNone","original_language":"eng","persons":["Aaron Williams"],"tags":["bucharest","479","2019","Keynote"],"view_count":198,"promoted":false,"date":"2019-08-29T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2025-07-04T00:45:05.023+02:00","length":1788,"duration":1788,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/479-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/479-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/479-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/479-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-479-using-gpu-acceleration-to-interact-with-open-street-map-at-planet-scale","url":"https://api.media.ccc.de/public/events/43e2163d-d0f7-5b45-945b-25dd8c57118b","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7465,"event_guid":"d2b2bdd0-36fa-5ae1-aba0-a38960010e3b","weight":7},{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":7},{"event_id":7482,"event_guid":"89395e98-1ee1-5eee-ae26-cbaa54630177","weight":3},{"event_id":7487,"event_guid":"6f1b8b15-b44a-592c-b3e9-96bd9e0fbce3","weight":10},{"event_id":7488,"event_guid":"0a3e23aa-d593-58cd-a3a1-7991e3a3a064","weight":7},{"event_id":7492,"event_guid":"f65e1c2f-8bde-5c89-a128-e113b0b9a3f6","weight":10},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":10},{"event_id":7540,"event_guid":"835f3234-2e2a-5d75-a3f3-7c822e225d60","weight":1},{"event_id":7552,"event_guid":"4c2f4b81-1316-502d-870c-dc39567b782e","weight":9},{"event_id":7607,"event_guid":"d0794cae-d707-584c-8879-6c438a603486","weight":3},{"event_id":7618,"event_guid":"6ed3f0f2-a47f-5229-b734-0c911d11f597","weight":2},{"event_id":7634,"event_guid":"09fd4e88-d4b2-524b-aecf-da9a0bed1c71","weight":1},{"event_id":7662,"event_guid":"a8fbf537-cbe1-5f17-aa73-97d64132f660","weight":2},{"event_id":7663,"event_guid":"1b265f5f-a622-52e0-a2a4-88105aa09aba","weight":2},{"event_id":7667,"event_guid":"4bc8bbe5-cb04-5a2b-b441-a696be055948","weight":6},{"event_id":7692,"event_guid":"3c0ea464-ce0e-5676-a977-075148d7bbdd","weight":8},{"event_id":7695,"event_guid":"5df0ebe1-cfe2-54c4-a0c8-40e35a6de826","weight":6},{"event_id":7710,"event_guid":"9bce8e1a-0dc8-5c82-977c-23dccd115e89","weight":8},{"event_id":7733,"event_guid":"0ba5c644-2353-5225-972e-6e3958f74f3e","weight":12},{"event_id":7756,"event_guid":"c4299de5-e39e-576d-93bb-7ae47fee42af","weight":4}]},{"guid":"1c58bd3e-15f6-51a3-af44-9d6a75f31556","title":"Working with 3D city models in Python","subtitle":null,"slug":"bucharest-26-working-with-3d-city-models-in-python","link":"https://talks.2019.foss4g.org/bucharest/talk/CXAACL/","description":"Semantic 3D city models are one of the cornerstones of the so-called \"smart city\" applications, yet they are very difficult to manipulate/edit/update.

And to parse one? We did, and we didn't like it. Therefore we created a developer-friendly JSON implementation of the CityGML data model.

To fulfill this demand, we developed a new Web Application Prototype, sponsored by Swisstopo, using the latest Free and Open Source Technologies. The new application integrates some of the today’s best OSGeo projects and will be available (summer 2019) as a modular open source solution on GitHub and ready to use in a docker container available on Docker Hub.

Recently the European Commission has entrusted ECMWF with the implementation of the Copernicus Climate Change Service (C3S), and Atmosphere Monitoring Service (CAMS), opening up the access to a huge amount of environmental data.  \nECMWF has a long experience to decode, manipulate and visualise GRIB and NetCDF data. This talk will present how with the help  of community open source tools users can more easily explore these large datasets.  \nBut even if users have the right tools and knowledge to manipulate the data, the amount of data to transfer is still a bottleneck. It is why ECMWF embarked in various projects to build and use cloud environments. One of these is the EU-funded Horizon 2020 HiDALGO project, which explores the building of workflows using these tools over various HPC and cloud environments. Open source plays again a vital role to make this happen. First findings of this exciting new work will be presented in this talk.\n\nNone","original_language":"eng","persons":["Milana Vuckovic","Sylvie","Stephan Siemen"],"tags":["bucharest","321","General"],"view_count":33,"promoted":false,"date":"2019-08-30T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2024-12-02T16:15:02.731+01:00","length":1116,"duration":1116,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/321-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/321-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/321-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/321-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-321-building-cloud-environments-with-open-source-software-to-offer-processing-of-large-environmental-data-sets","url":"https://api.media.ccc.de/public/events/5b35bf19-e251-5dea-96f1-49e2f0f88d09","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":2},{"event_id":7468,"event_guid":"43d9cc0e-3fb9-55b2-a3a1-b9cfbe928e23","weight":3},{"event_id":7482,"event_guid":"89395e98-1ee1-5eee-ae26-cbaa54630177","weight":1},{"event_id":7492,"event_guid":"f65e1c2f-8bde-5c89-a128-e113b0b9a3f6","weight":2},{"event_id":7493,"event_guid":"dd3738e7-3aa6-580a-a526-d9087b930c84","weight":1},{"event_id":7504,"event_guid":"c54aa667-78de-55fb-85e7-60f2eaffd2a4","weight":1},{"event_id":7533,"event_guid":"bff8e480-f2e6-5fb7-a945-fed5e6b06f77","weight":1},{"event_id":7534,"event_guid":"3fc26cc4-962e-5f27-a92b-c01e86d12100","weight":1},{"event_id":7552,"event_guid":"4c2f4b81-1316-502d-870c-dc39567b782e","weight":2},{"event_id":7553,"event_guid":"9f0999f8-6941-5308-b1a8-f094c738245f","weight":2},{"event_id":7561,"event_guid":"1125685c-9fdc-5572-89c0-8bc80c7df3e0","weight":4},{"event_id":7562,"event_guid":"79cf5a8f-8601-533e-82c5-56626447534c","weight":2},{"event_id":7573,"event_guid":"347ab764-8ae3-58fe-87a0-18dca9880c63","weight":3},{"event_id":7578,"event_guid":"d5d6bac8-cb8a-504a-9a3f-ced5c377e1bd","weight":1},{"event_id":7590,"event_guid":"0bdb57e7-edb8-50e8-a60e-4ec5480e14b9","weight":1},{"event_id":7607,"event_guid":"d0794cae-d707-584c-8879-6c438a603486","weight":2},{"event_id":7614,"event_guid":"7347a409-8f11-53a7-b855-39fcf0d8c2ae","weight":1},{"event_id":7616,"event_guid":"23bc1246-3fcb-5ce4-ac80-f8c176a25d97","weight":1},{"event_id":7618,"event_guid":"6ed3f0f2-a47f-5229-b734-0c911d11f597","weight":1},{"event_id":7632,"event_guid":"99a39bf7-5c95-5bc3-947a-55e28aa0a042","weight":1},{"event_id":7661,"event_guid":"afb75703-96a4-5546-b1fa-493154ef35ae","weight":1},{"event_id":7662,"event_guid":"a8fbf537-cbe1-5f17-aa73-97d64132f660","weight":1},{"event_id":7663,"event_guid":"1b265f5f-a622-52e0-a2a4-88105aa09aba","weight":2},{"event_id":7664,"event_guid":"bc480eaa-8db8-54d0-bc53-32a81725f2d9","weight":2},{"event_id":7667,"event_guid":"4bc8bbe5-cb04-5a2b-b441-a696be055948","weight":2},{"event_id":7669,"event_guid":"7627a093-69e4-5c72-b8b5-0f05c27ce815","weight":2},{"event_id":7674,"event_guid":"ac484924-85f6-5195-bf5b-9f689f24ef57","weight":1},{"event_id":7694,"event_guid":"05466dda-8c63-57a3-a1ff-ebeff2abaa92","weight":2},{"event_id":7695,"event_guid":"5df0ebe1-cfe2-54c4-a0c8-40e35a6de826","weight":2},{"event_id":7701,"event_guid":"d3a697b4-8bc4-57ba-934c-2747fbec39ab","weight":2},{"event_id":7709,"event_guid":"936a0a3d-27d2-5bb7-a59a-336837047e72","weight":1},{"event_id":7733,"event_guid":"0ba5c644-2353-5225-972e-6e3958f74f3e","weight":2}]},{"guid":"d0794cae-d707-584c-8879-6c438a603486","title":"Are we going back to Command Line GIS ?","subtitle":null,"slug":"bucharest-212-are-we-going-back-to-command-line-gis-","link":"https://talks.2019.foss4g.org/bucharest/talk/DKL3EW/","description":"After 05:00 the audio from the speaker is masked by audio from the video that is playing. \n\nIn the early ages of Computer Science, there was only Command Line Interface (CLI).\nNo mouse, no windows. But computers was already able to do more than just calculus.\n\nFirst of this kind -- in the early eighties ! -- GRASS GIS was able to manipulate,\nanalyze and visualize geospatial data. All in CLI. But it was frightening for\nmost users. CLI is terrifying.\n\nThen graphical interfaces arrived with windows and mouses. Computers started to\nbe cheaper and more affordable. Almost everyone now can own and use a computer.\nWith a graphical interface.\n\nLess scary, more accessible. And GIS followed the trend. ESRI created ArcMap,\nQGIS was born. Even GRASS GIS got a Graphical User Interface at some point.\n\nBut isn't CLI making a come back ? Quietly ? Even in our small geospatial heaven ?\nLet's have a look at behind the curtain and see what CLI can offer nowadays with\nthe Python and R datascience stacks.\n\nLet's look at CLI GIS, right in the eye !\n\nBy the end of the talk audience members will :\n* not be afraid of CLI anymore (let's hope)\n* might want to learn a scripting language and explore console mode\n* want to combine best of both worlds\n\nNone","original_language":"eng","persons":["Nicolas Roelandt"],"tags":["bucharest","212","2019","General"],"view_count":481,"promoted":false,"date":"2019-08-29T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2024-12-12T15:45:02.374+01:00","length":750,"duration":750,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/212-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/212-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/212-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/212-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-212-are-we-going-back-to-command-line-gis-","url":"https://api.media.ccc.de/public/events/d0794cae-d707-584c-8879-6c438a603486","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7466,"event_guid":"98c0417b-cdfd-57b3-9411-14f9f465f5b9","weight":24},{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":39},{"event_id":7487,"event_guid":"6f1b8b15-b44a-592c-b3e9-96bd9e0fbce3","weight":32},{"event_id":7492,"event_guid":"f65e1c2f-8bde-5c89-a128-e113b0b9a3f6","weight":1},{"event_id":7504,"event_guid":"c54aa667-78de-55fb-85e7-60f2eaffd2a4","weight":3},{"event_id":7505,"event_guid":"5ac07c14-e2f1-5cba-a86f-047443848af5","weight":3},{"event_id":7512,"event_guid":"88c1d544-049b-5622-b197-03b8894a39f7","weight":2},{"event_id":7514,"event_guid":"0d63b0b4-259d-5114-8c8f-18604b514f7d","weight":2},{"event_id":7518,"event_guid":"8773035b-d16c-5cf3-902d-43abc7e5dab7","weight":13},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":46},{"event_id":7533,"event_guid":"bff8e480-f2e6-5fb7-a945-fed5e6b06f77","weight":2},{"event_id":7534,"event_guid":"3fc26cc4-962e-5f27-a92b-c01e86d12100","weight":2},{"event_id":7536,"event_guid":"9f921eab-53c5-5ce7-9489-45a586162248","weight":1},{"event_id":7554,"event_guid":"20bb70f9-e0ab-5d46-9e99-71cd75e04251","weight":6},{"event_id":7561,"event_guid":"1125685c-9fdc-5572-89c0-8bc80c7df3e0","weight":1},{"event_id":7573,"event_guid":"347ab764-8ae3-58fe-87a0-18dca9880c63","weight":1},{"event_id":7579,"event_guid":"0112454d-62b2-5132-8971-73c7fdb972d0","weight":30},{"event_id":7608,"event_guid":"13e2ef4d-8375-580b-a797-c54a85faa0aa","weight":2},{"event_id":7614,"event_guid":"7347a409-8f11-53a7-b855-39fcf0d8c2ae","weight":1},{"event_id":7616,"event_guid":"23bc1246-3fcb-5ce4-ac80-f8c176a25d97","weight":1},{"event_id":7618,"event_guid":"6ed3f0f2-a47f-5229-b734-0c911d11f597","weight":1},{"event_id":7619,"event_guid":"21ffa487-5dfd-57d3-acce-8fd048ead7cf","weight":3},{"event_id":7623,"event_guid":"d7305220-5dac-5581-bf1b-14e735c39756","weight":2},{"event_id":7630,"event_guid":"2922816b-f00a-5fc1-97e6-69df1a0c98ab","weight":1},{"event_id":7632,"event_guid":"99a39bf7-5c95-5bc3-947a-55e28aa0a042","weight":1},{"event_id":7652,"event_guid":"e04c27d0-8ff8-5bf4-b932-34db4e4fdf5b","weight":23},{"event_id":7658,"event_guid":"361e8802-42c9-542d-8fcd-05647efe3d84","weight":1},{"event_id":7661,"event_guid":"afb75703-96a4-5546-b1fa-493154ef35ae","weight":1},{"event_id":7666,"event_guid":"5b35bf19-e251-5dea-96f1-49e2f0f88d09","weight":1},{"event_id":7667,"event_guid":"4bc8bbe5-cb04-5a2b-b441-a696be055948","weight":12},{"event_id":7669,"event_guid":"7627a093-69e4-5c72-b8b5-0f05c27ce815","weight":6},{"event_id":7674,"event_guid":"ac484924-85f6-5195-bf5b-9f689f24ef57","weight":2},{"event_id":7681,"event_guid":"a1326956-88be-5af4-b747-5cefc95e8232","weight":18},{"event_id":7692,"event_guid":"3c0ea464-ce0e-5676-a977-075148d7bbdd","weight":33},{"event_id":7694,"event_guid":"05466dda-8c63-57a3-a1ff-ebeff2abaa92","weight":2},{"event_id":7695,"event_guid":"5df0ebe1-cfe2-54c4-a0c8-40e35a6de826","weight":20},{"event_id":7709,"event_guid":"936a0a3d-27d2-5bb7-a59a-336837047e72","weight":2},{"event_id":7729,"event_guid":"9d030aa8-27aa-509b-913f-ee9eff97257b","weight":19},{"event_id":7749,"event_guid":"5117b85e-052d-5b96-bcc3-f14e953b887a","weight":17},{"event_id":7756,"event_guid":"c4299de5-e39e-576d-93bb-7ae47fee42af","weight":28}]},{"guid":"89395e98-1ee1-5eee-ae26-cbaa54630177","title":"An OSM-based 3D Street Map of the Earth","subtitle":null,"slug":"bucharest-254-an-osm-based-3d-street-map-of-the-earth","link":"https://talks.2019.foss4g.org/bucharest/talk/SVGVBK/","description":"OSM has long since established itself as the leading global street database.

first- and second-generation new towns have been developed as self-sufficient cities that can accommodate about 100,000 people. However, many new town residents are commuting to a longer distance and feel uncomfortable about their last mile commuting trip. A viable option to address this issue is to introduce a shared mobility service to their last mile trip from a local transportation hub to their home. This presentation analyzes these last miles commuting trip using smart card data, navigation map subscribers' travel patterns, and telecom carrier's Origin and Destination (OD) data on people’s movement. And then author predict the converted shared mobility demand from the calculated existing last mile trip. Lastly, author propose sharing port locations for car sharing, ride sharing, electric bike and personal mobility such as kick boards, etc., based on predicted shared mobility demand. In this presentation, the author also would like to share the trial and error in the process of spatial analysis and design.\n\nKeyword: Last Mile Commuting Trip, Shared Mobility, Personal Mobility,

number of sponsors, many of them very large companies, found at FOSS4G events indicates that there are significant commercial interests and opportunities associated with free and open source software (FOSS) technologies. This talk will describe several recurring patterns and business models for “monetizing” open source technologies, while also - and crucially - contributing back to FOSS communities. The talk will elaborate on the following three main models:\n\n1. Providing value added services and support to open source projects\n2. Leveraging/incorporating open source technologies to deliver products/SaaS\n3. Open sourcing your commercial technology\n\nThe talk will also provide real world examples of each of these models from the perspective of a commercial business that is actively engaged in a variety of FOSS activities. The talk will also examine some new and emerging trends including open data being incorporated into commercial platforms.\n\nNone","original_language":"eng","persons":["Michael Terner"],"tags":["bucharest","152","2019","General"],"view_count":216,"promoted":false,"date":"2019-08-29T00:00:00.000+02:00","release_date":"2019-08-29T02:00:00.000+02:00","updated_at":"2025-02-23T00:30:04.274+01:00","length":1513,"duration":1513,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/152-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/152-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/152-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/152-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-152-open-source-business-models-making-money-playing-by-the-rules-","url":"https://api.media.ccc.de/public/events/8773035b-d16c-5cf3-902d-43abc7e5dab7","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7465,"event_guid":"d2b2bdd0-36fa-5ae1-aba0-a38960010e3b","weight":7},{"event_id":7466,"event_guid":"98c0417b-cdfd-57b3-9411-14f9f465f5b9","weight":5},{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":13},{"event_id":7484,"event_guid":"b4d6c8c6-688b-5273-aa8f-a2044128ac13","weight":1},{"event_id":7488,"event_guid":"0a3e23aa-d593-58cd-a3a1-7991e3a3a064","weight":1},{"event_id":7491,"event_guid":"7ce19c2c-7bc3-5ba7-b454-b383a7c58c6c","weight":1},{"event_id":7512,"event_guid":"88c1d544-049b-5622-b197-03b8894a39f7","weight":2},{"event_id":7514,"event_guid":"0d63b0b4-259d-5114-8c8f-18604b514f7d","weight":2},{"event_id":7517,"event_guid":"ef1a3ce2-61bf-53e1-8f97-acb738c219f9","weight":1},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":12},{"event_id":7523,"event_guid":"a95cf31f-07d2-5255-bfa2-6fb38923a15f","weight":1},{"event_id":7524,"event_guid":"f58c39cb-2250-51b5-8902-d52f713c934b","weight":1},{"event_id":7533,"event_guid":"bff8e480-f2e6-5fb7-a945-fed5e6b06f77","weight":1},{"event_id":7534,"event_guid":"3fc26cc4-962e-5f27-a92b-c01e86d12100","weight":1},{"event_id":7537,"event_guid":"14a1b81d-47c2-560c-9525-26e35f4caf54","weight":1},{"event_id":7552,"event_guid":"4c2f4b81-1316-502d-870c-dc39567b782e","weight":1},{"event_id":7553,"event_guid":"9f0999f8-6941-5308-b1a8-f094c738245f","weight":12},{"event_id":7555,"event_guid":"a641fc9b-2eb6-5580-8acc-4236e227de4e","weight":1},{"event_id":7559,"event_guid":"69de3e04-de0f-5325-9862-023143b3252b","weight":1},{"event_id":7573,"event_guid":"347ab764-8ae3-58fe-87a0-18dca9880c63","weight":1},{"event_id":7579,"event_guid":"0112454d-62b2-5132-8971-73c7fdb972d0","weight":11},{"event_id":7603,"event_guid":"21cccc72-7587-5bb7-a0de-8dd64615c4d9","weight":1},{"event_id":7607,"event_guid":"d0794cae-d707-584c-8879-6c438a603486","weight":13},{"event_id":7624,"event_guid":"69079f64-448d-55b5-9cb3-7089547c370d","weight":7},{"event_id":7626,"event_guid":"227ae37a-41aa-53d7-944a-2e9b7c8d99a7","weight":7},{"event_id":7632,"event_guid":"99a39bf7-5c95-5bc3-947a-55e28aa0a042","weight":1},{"event_id":7652,"event_guid":"e04c27d0-8ff8-5bf4-b932-34db4e4fdf5b","weight":7},{"event_id":7667,"event_guid":"4bc8bbe5-cb04-5a2b-b441-a696be055948","weight":6},{"event_id":7681,"event_guid":"a1326956-88be-5af4-b747-5cefc95e8232","weight":6},{"event_id":7695,"event_guid":"5df0ebe1-cfe2-54c4-a0c8-40e35a6de826","weight":9},{"event_id":7729,"event_guid":"9d030aa8-27aa-509b-913f-ee9eff97257b","weight":8},{"event_id":7749,"event_guid":"5117b85e-052d-5b96-bcc3-f14e953b887a","weight":13},{"event_id":7756,"event_guid":"c4299de5-e39e-576d-93bb-7ae47fee42af","weight":11}]},{"guid":"63e1996e-b296-55cb-9fd6-4e4d22e878f6","title":"National Forest Inventory (NFI) in the Czech Republic presented in Graphs and Maps","subtitle":null,"slug":"bucharest-445-national-forest-inventory-nfi-in-the-czech-republic-presented-in-graphs-and-maps","link":"https://talks.2019.foss4g.org/bucharest/talk/BQDXMZ/","description":"National Forest Inventory is an independent survey on the state and development of forests. It is based on mathematical–statistical models.

However, they expand the surface area of the Earth respectively by 50% and 200%, imposing serious overheads in data storage, and more importantly, computation costs. While an equal-area projection is the evident solution, those supported by FOSS4G are scant; a choice is not straightforward.\n\nISRIC, the World Data Centre for Soils, creates and serves global high resolution maps of continuous estimates of soil properties and soil classes. ISRIC had until recently created its products in the millinery projection of Marinus of Tyre, but in face of ramping computation costs, it initiated a process to adopt an equal-area projection. After carefully benchmarking various candidates, the option rested on the Homolosine, a modern projection developed by J.P. Goode that is supported both by PROJ and GDAL.\n\nThis address details the advantages of the Homolosine projection over other FOSS4G supported equal-area projections. It also highlights the limitations of FOSS4G in working with the Homolosine and the strategies to overcome them.\n\n![](https://files.mastodon.social/media_attachments/files/013/541/730/original/48ce103c58e42c90.png)\n\nNone","original_language":"eng","persons":["Luís Moreira de

economically important global ecosystems associated with some of the largest coastal marine fisheries and the majority of global wetlands. They also the most extensive coastal lowlands threatened by climate change and human activities such as agriculture, navigation, fisheries, forestry, fossil energy production and industrial urban development. Under climate- and human-induced sea level rise, sediment trapping behind dams and destruction of natural protective ecosystems, deltas are currently sinking at accelerating rates. \n\nDeltas maintenance and reconstruction depends on effective monitoring of vast and intricate areas of channels, lakes, wetlands, beaches, and islands that cannot be effectively accomplished on the ground without prohibitive expense. If ignored, disappearance of deltas will soon have devastating consequences for the livelihood of the half billion people who live in these coastal regions and lead to mass migration. I’ll present ideas \u0026 initiatives that seek to monitor deltas remotely and plug spatially-distributed data into models of hydrology, morphology, and ecosystem dynamics using remotely-sensed data

new world of 3D mapping has taken little notice of time-proven rules of cartography, as if arbitrary viewing angles could somehow obliterate the need to convey a clear hierarchy of features. In this talk we will show how the vector styling capabilities in vts-geospatial may be used to overcome that long-standing shortcoming. From the choice of a basemap through the definition of intellectual and visual hierarchies to the coding of visual style, we will show how to produce 3D maps which aspire not only to the aesthetical appeal but also to the information value of a real cartographic product.\n\nNone","original_language":"eng","persons":["Ondřej Procházka"],"tags":["bucharest","331","2019","General"],"view_count":115,"promoted":false,"date":"2019-08-28T00:00:00.000+02:00","release_date":"2019-08-29T02:00:00.000+02:00","updated_at":"2025-02-16T01:00:03.481+01:00","length":1293,"duration":1293,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/331-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/331-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/331-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/331-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-331-visual-hierarchies-in-3d-cartography-with-vts-geospatial","url":"https://api.media.ccc.de/public/events/175e2989-1005-5266-8928-9bb1247bf423","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":2},{"event_id":7473,"event_guid":"feda735f-5467-56f0-9ddf-55cefdf60199","weight":4},{"event_id":7482,"event_guid":"89395e98-1ee1-5eee-ae26-cbaa54630177","weight":5},{"event_id":7487,"event_guid":"6f1b8b15-b44a-592c-b3e9-96bd9e0fbce3","weight":2},{"event_id":7500,"event_guid":"e72bec3a-da22-50b9-a6d6-11cedeb37917","weight":6},{"event_id":7501,"event_guid":"a4aa4222-f2ca-5e0c-94f6-4c7a3595d1a2","weight":4},{"event_id":7526,"event_guid":"fd5614a8-535f-5069-8f69-3a9983d37830","weight":3},{"event_id":7550,"event_guid":"53494dbe-b19b-5e77-a2d1-9cb5a6d5447d","weight":6},{"event_id":7652,"event_guid":"e04c27d0-8ff8-5bf4-b932-34db4e4fdf5b","weight":2},{"event_id":7692,"event_guid":"3c0ea464-ce0e-5676-a977-075148d7bbdd","weight":2},{"event_id":7710,"event_guid":"9bce8e1a-0dc8-5c82-977c-23dccd115e89","weight":4}]},{"guid":"89f564bf-e743-5086-a372-478a49b0d7ce","title":"Street-level Imagery as Open Data","subtitle":null,"slug":"bucharest-315-street-level-imagery-as-open-data","link":"https://talks.2019.foss4g.org/bucharest/talk/LKFNAS/","description":"Not all open data comes in traditional geospatial formats: for years, organizations around the world have collected photo and video logs of roads for annual surveys, but until recently these have been overlooked as a form of open data.

learning crowed based spatio-temporal indicators to model the components of the WorldRiskIndex based on OSM tags and machine learning\n\nClimate change is already reality in many parts of the world and even more threatening our future well-being. The SDG 1.5 explicitly aims to reduce by 2030 the vulnerability and exposure to climate related hazards. The World Risk Index (WRI) is one well-respected approach in profiling countries risk to natural hazard. To effectively monitor development and detect decision knots on the climate resilience pathway (IPCC 2014) data  of high resolution in space and time about the worlds countries is of urgent importance. Hence, the core of this work is the development of learning indicators. Learning in the sense of a methodological approach combining PostGIS for data management, R for statistical learning and QGIS for spatial analysis on crowd based information assessing the OSM-database and addressing the need of societal learning in the face of severe climate change. The World Risk Index (Birkmann et al. 2015) will guide the supervised learning part resulting in an indicator set derived from OSM tags, establishing on one hand an open risk index and adding deep explanatory power to its components by a qualitative discussion of the OSM themes. The second part explores with unsupervised algorithms the inherent characteristic of country groups classified by the open risk index and deduces common patterns of socio-economic vulnerability but also societal resilience. Hence, the inherent challenge of this work is to substitute existing static indicators with new dynamic indicators, but not only substituting them but also painting a more detailed picture. Moreover, new data sources still questioned often by their reliability compared to World Bank or census data, and therefore its opportunities are neglected instead of critically exploring the potential. Therefore, this thorough statistical approach in quantifying uncertainty contributes to the acceptance and hence use of crowd based information adding necessary reliability for policy and planning. This unique combination is not yet done and bares huge potential moreover united with the open source geo community to contribute a little piece of the puzzle for achieving the SDG 1.5.\n\nNone","original_language":"eng","persons":["Jörn Birkmann","Holger Sauter","Daniel Feldmeyer"],"tags":["bucharest","60","Academic"],"view_count":43,"promoted":false,"date":"2019-08-29T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2025-01-03T23:00:09.186+01:00","length":1603,"duration":1603,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/60-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/60-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/60-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/60-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-60-an-open-risk-index-with-learning-indicators-from-osm-tags-developed-by-machine-learning-and-trained-with-the-worldriskindex","url":"https://api.media.ccc.de/public/events/3394a8b8-5954-531f-bbab-877ae065fcee","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":1},{"event_id":7524,"event_guid":"f58c39cb-2250-51b5-8902-d52f713c934b","weight":1},{"event_id":7525,"event_guid":"9cb9910c-3b3f-5cec-830b-24e93de3edc9","weight":1},{"event_id":7532,"event_guid":"e7956d52-af40-563e-ae3e-1df491ad6591","weight":1},{"event_id":7581,"event_guid":"f3a8dd85-9308-553a-928d-bfd47824fbd7","weight":1},{"event_id":7585,"event_guid":"3e149633-f405-5e9b-850c-b0934537b6d8","weight":1},{"event_id":7607,"event_guid":"d0794cae-d707-584c-8879-6c438a603486","weight":1},{"event_id":7613,"event_guid":"0b7d0b85-cf67-5382-aba4-9035a9e7963a","weight":2},{"event_id":7623,"event_guid":"d7305220-5dac-5581-bf1b-14e735c39756","weight":1},{"event_id":7642,"event_guid":"c51c6100-e015-53bc-8296-486d5e4e3ce7","weight":2},{"event_id":7645,"event_guid":"efd996c1-5096-5b23-bf42-3dd6818dc072","weight":1},{"event_id":7652,"event_guid":"e04c27d0-8ff8-5bf4-b932-34db4e4fdf5b","weight":1},{"event_id":7653,"event_guid":"2f97a6f3-e441-505a-8be2-e95554c44430","weight":2},{"event_id":7660,"event_guid":"17585226-58b0-51da-a3b6-3c41ff51db2c","weight":1},{"event_id":7667,"event_guid":"4bc8bbe5-cb04-5a2b-b441-a696be055948","weight":1},{"event_id":7692,"event_guid":"3c0ea464-ce0e-5676-a977-075148d7bbdd","weight":2},{"event_id":7693,"event_guid":"7b831cc0-2092-52d2-bb54-f219e39a666f","weight":2},{"event_id":7696,"event_guid":"cf0c6d43-7a50-5d88-b6dd-db5aa818aff8","weight":2},{"event_id":7701,"event_guid":"d3a697b4-8bc4-57ba-934c-2747fbec39ab","weight":1},{"event_id":7703,"event_guid":"38fb4b40-3935-5dbc-b54a-551830e317d8","weight":1},{"event_id":7750,"event_guid":"123bf2f0-6f17-5563-96c7-430cfe28dd0d","weight":2},{"event_id":7755,"event_guid":"f651ccfa-c224-5cfa-b76b-f7b44b4ef563","weight":1}]},{"guid":"eb077a88-d0d1-5a87-bc50-68bacdeaf135","title":"OSGeo UN Committee Educational Challenges: A use case of sharing software and experience from all over the world","subtitle":null,"slug":"bucharest-85-osgeo-un-committee-educational-challenges-a-use-case-of-sharing-software-and-experience-from-all-over-the-world","link":"https://talks.2019.foss4g.org/bucharest/talk/SGGAGJ/","description":"The OSGeo United Nations (UN) Committee promotes the development and use of open source software that meets UN needs and supports the aims of the UN. Following a meeting between the OSGeo Board of Directors and the UN GIS team at the FOSS4G conference in Seoul, Korea, in September 2015, the Committee has mainly worked on the UN Open GIS Initiative, a project \"... to identify and develop an Open Source GIS bundle that meets the requirements of UN operations, taking full advantage of the expertise of mission partners including partner nations, technology contributing countries, international organisations, academia, NGOs, private sector\". In 2018, the OSGeo UN Committee called for proposals for developing open geospatial educational materials as a part of its activities. There were three challenges: the first two (one of them sponsored by Boundless) are related to the UN Open GIS Initiative. \n\nThe first challenge, related to UN Open GIS - Spiral 1, aims at the development of education material that teaches users how to apply the GeoSHAPE platform. GeoSHAPE is a free and open source geospatial collaborative platform created from various open source projects. The developed material provides a guide on how to create, edit and share critical data on an integrated dynamic map in near real time, view map updates by users from anywhere in the world and use GeoSHAPE exchange in connected and disconnected environments. The course is structured with content to suit novice, intermediate and advanced users.\n\nThe second challenge supports UN Open GIS - Spiral 3, which provides geo-analytical solutions for the UN. The feasibility of the analytical functions developed as part of Spiral 3 were  tested against an Ebola Epidemic use case. Requirements for developing suitable applications and methodologies based on actual UN operational cases were defined in 2017. Members of the UN Open GIS - Spiral 3 developed a geo-analytical library, called \"Processing Toolbox\", which is a plug-in for uDig, an open source desktop GIS. The training material developed in the frame of the OSGeo UN Challenge provides an introduction to the use of the algorithms for environmental analysis in the uDig Processing Toolbox, specifically those related to ecology and ecosystems identification. The training material for Spiral 3 is designed as a step-by-step tutorial, using algorithms in the uDig Processing Toolbox. While working through the tutorial, the user is familiarized with the tools covering all the available macro sections. After completing the tutorial, a user will be able to find the needed algorithms to solve a specific use case.\n\nThe presentation deals with the description of the UN Open GIS Challenge and the open training materials developed under this initiative. The material is available under an open license and can therefore be reused by anybody.\n\nNone","original_language":"eng","persons":["HaeKyong Kang","Ketty Adoch","Silvia Franceschi","Maria

Geography with Open GIS as a Transformative Introductory Higher Education Course","subtitle":null,"slug":"bucharest-94-human-geography-with-open-gis-as-a-transformative-introductory-higher-education-course","link":"https://talks.2019.foss4g.org/bucharest/talk/EZVUUY/","description":"Curricula in geography and GIS can be transformed by integrating open source GIS with critical human geography. This integration requires students to develop strong skills in assessing error and uncertainty and in questioning the powerful social implications of spatial information technologies, and requires faculty and students to develop new open curricula, features and algorithms to facilitate teaching introductory spatial analysis. Building on three semesters of experimentation with an advanced-level integrated open and critical GIS course, I have transformed a large introductory proprietary GIS course into a critical human geography course with open-source QGIS.\u003cbr\u003e\n\nThroughout the curricula, open GIS techniques are mapped to critical human geography concepts. Novice GIS students learn fundamental techniques while also learning to question the political economics, social and cultural forces, and instrumental logics that shape GIS data, software algorithms, visualizations, and social impacts. For example, students' first exercise is to practice radical cartography of disabled mobilities. On one hand, they learn fundamental techniques of the vector data model, planning a data collection schema, using a Leaflet application exposing the global positioning system location services on their phones, querying OpenStreetMap data, and creating a QGIS map visualization and print layout of wheelchair users' accessibility on campus. On the other hand, they confront and appreciate social power in construction of the built environment and campus maps, socially differentiated mobility in physical and cognitive space, and potential for GIS to challenge the status quo. \u003cbr\u003e\n\nWhat are the substantive differences between teaching GIS and teaching human geography with GIS, or between teaching open and proprietary GIS? Teaching human geography places critical questions about the society and society's interaction with spatial technology first, while the spatial technology itself is not black-boxed, infallible, or determinant. Taken together, students first ask how GIS can be used for critical inquiry and when GIS fails or delivers unsatisfactory results, they ask how open GIS can be altered to produce better answers. The fallibility of open GIS requires a pedagogical focus on assessing error and uncertainty: students must learn to confidently assess the integrity of each algorithms' results. The accessibility and malleability of open GIS enables students and faculty to change GIS as we use it, and open GIS can benefit from cohorts of novice students critically engaging with the technology. New forms of GIS users and applications emerge as students diffuse open GIS technology through other university courses and internships with grassroots and non-governmental organizations. New forms of open GIS software emerge as students help create more user-friendly open GIS for novices and repurpose open GIS for critical inquiry.\n\nNone","original_language":"eng","persons":["Joseph

Furthermore, most of the UN missions take place in regions where geospatial data are very limited. Spiral 4 has been working to develop and provide several solutions for divers and difficult requirements from the UN. In this talk, we will present the vision and solutions that we are developing so far, such as live drone maps, open geo-CMS, and quality control tools. We will also discuss and share the lessons learned from Spiral 4.\n\nNone","original_language":"eng","persons":["Yong-Bok Choi","Byeong-Gon Kim","Impyeong Lee","Kwang Woo Nam","Jong-Hoon Lee","Anandavel Kannan","Ki-Joune Li"],"tags":["bucharest","305","2019","General"],"view_count":26,"promoted":false,"date":"2019-08-28T00:00:00.000+02:00","release_date":"2019-08-29T02:00:00.000+02:00","updated_at":"2023-02-22T11:45:02.726+01:00","length":1583,"duration":1583,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/305-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/305-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/305-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/305-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-305-the-un-open-gis-initiative-spiral-4-for-geospatial-data-collection","url":"https://api.media.ccc.de/public/events/27f015cf-fe4e-55b2-bdb7-01a850ca00af","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7462,"event_guid":"bc0ea171-a661-56f9-a518-e32c84bbcf8b","weight":2},{"event_id":7468,"event_guid":"43d9cc0e-3fb9-55b2-a3a1-b9cfbe928e23","weight":1},{"event_id":7471,"event_guid":"3c2d5b68-ca8e-5c4e-9110-59ad868cfc70","weight":1},{"event_id":7478,"event_guid":"ae1cdec5-93fe-5638-a167-faa6e81cf9c6","weight":1},{"event_id":7479,"event_guid":"5cb82c9e-bc84-54e2-a40d-60b78f35ef46","weight":1},{"event_id":7480,"event_guid":"603a5649-724a-53d7-ac20-ff7d520696d3","weight":1},{"event_id":7488,"event_guid":"0a3e23aa-d593-58cd-a3a1-7991e3a3a064","weight":1},{"event_id":7492,"event_guid":"f65e1c2f-8bde-5c89-a128-e113b0b9a3f6","weight":1},{"event_id":7495,"event_guid":"bffc8bd9-0df8-5543-8c24-254c05092bbd","weight":1},{"event_id":7510,"event_guid":"ab6c65d7-f9df-563f-b9bb-e36c128e9ab4","weight":1},{"event_id":7512,"event_guid":"88c1d544-049b-5622-b197-03b8894a39f7","weight":4},{"event_id":7515,"event_guid":"b744af16-2f4c-5151-bca1-91449f719965","weight":1},{"event_id":7518,"event_guid":"8773035b-d16c-5cf3-902d-43abc7e5dab7","weight":1},{"event_id":7520,"event_guid":"2e1e926d-3eaa-5fa1-83b3-1a8e001df0c6","weight":1},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":2},{"event_id":7524,"event_guid":"f58c39cb-2250-51b5-8902-d52f713c934b","weight":1},{"event_id":7525,"event_guid":"9cb9910c-3b3f-5cec-830b-24e93de3edc9","weight":3},{"event_id":7530,"event_guid":"27739ac4-67df-54da-a0f4-633bc7a9ac61","weight":1},{"event_id":7548,"event_guid":"8ca1b4b6-ee0c-5102-ab95-a978cd3b4d8c","weight":2},{"event_id":7552,"event_guid":"4c2f4b81-1316-502d-870c-dc39567b782e","weight":1},{"event_id":7553,"event_guid":"9f0999f8-6941-5308-b1a8-f094c738245f","weight":2},{"event_id":7554,"event_guid":"20bb70f9-e0ab-5d46-9e99-71cd75e04251","weight":1},{"event_id":7557,"event_guid":"ab693aa0-5ac8-533f-aeca-a8d39a36e86c","weight":1},{"event_id":7564,"event_guid":"faf1a4fd-2d2d-5622-a95a-c6488eeff404","weight":1},{"event_id":7579,"event_guid":"0112454d-62b2-5132-8971-73c7fdb972d0","weight":1},{"event_id":7593,"event_guid":"6a8c04d0-d372-5f16-87a2-96f537854ebc","weight":1},{"event_id":7607,"event_guid":"d0794cae-d707-584c-8879-6c438a603486","weight":1},{"event_id":7629,"event_guid":"43e2163d-d0f7-5b45-945b-25dd8c57118b","weight":2},{"event_id":7634,"event_guid":"09fd4e88-d4b2-524b-aecf-da9a0bed1c71","weight":1},{"event_id":7652,"event_guid":"e04c27d0-8ff8-5bf4-b932-34db4e4fdf5b","weight":1},{"event_id":7700,"event_guid":"a45f513c-23e0-512d-a69c-8163e5edf0d8","weight":1},{"event_id":7723,"event_guid":"8ef7bba2-4df3-5bf0-9208-b8f5badad5eb","weight":1},{"event_id":7729,"event_guid":"9d030aa8-27aa-509b-913f-ee9eff97257b","weight":3},{"event_id":7907,"event_guid":"61270840-b28d-53dc-984c-434b809bc8d2","weight":2}]},{"guid":"21ffa487-5dfd-57d3-acce-8fd048ead7cf","title":"Demystifying AI in Geo","subtitle":null,"slug":"bucharest-448-demystifying-ai-in-geo","link":"https://talks.2019.foss4g.org/bucharest/talk/JQTVFF/","description":"You are probably familiar with the terms artificial intelligence (AI), machine learning (ML) and deep learning (DL).

Italian alpine region (about 6200 Km2) with a forest coverage exceeding 60% of its whole surface. In the past, forest landscape has changed dramatically, especially in periods of forest over-exploitation.\nPrevious studies in some Trentino sub-regions (Val di Fassa, Paneveggio) have identified these changes and the current trend of forest growth at the expenses of open areas, such as pastures and grasslands, due to the abandonment of rural areas. This phenomenon leads to the rapid Alpine landscape change and profoundly affects the ecological features of mountain ecosystems. To be able to monitor and to take future actions about this trend it is fundamental to know in detail the historical situation of the progressive changes on the land use that occurred over Trentino.\nThe work aims to comprehensively reconstruct the forest cover of whole Trentino at high resolution (5m x 5m pixels) using a series of maps spanning a long period, consisting in historical maps, aerial images, remote sensed information and historical archives. The datasets were archived, processed and analyzed using the Free and Open Source Software (FOSS) GIS GRASS and QGIS. Historical maps include “Atlas Tyrolensis” (dated 1770), “Theresianischer Kataster” (dated 1859) and Italian Kingdom Forest Map (IKFM) of 1936. The aerial imagery dataset includes aerial images taken in 1954, which have been orthorectified during this research, and orthophotos available for years 1973, 1994, 2000, 2006, 2010 and 2016. Remote sensed information includes Landsat and recent Lidar data, while historical archives consist mostly in Forest Management Plans available since around 1950.\nThe versatility of the wide variety of modules supplied from the FOSS GRASS and QGIS enabled to perform a diverse set of analysis and pre-processing (e.g.:orthorectification) on a heterogeneous dataset of input images. We will focus on the different strategies and methodologies implemented in the FOSS GIS used to process the various types of geographic data, challenges for the future of the research and the fundamental role of the FOSS systems in this process.\nQuantifying forest change in the time-span of our dataset can be used to perform further analysis on ecosystem services, such as protection from soil erosion, and on modification of biome diversity and to create future change scenarios.\n\nNone","original_language":"eng","persons":["Marco Ciolli","Nicola La Porta","Clara Tattoni","Paolo Zatelli","Duccio Rocchini","Maria Cantiani","Stefano Gobbi"],"tags":["bucharest","63","2019","Academic"],"view_count":28,"promoted":false,"date":"2019-08-28T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2025-01-05T18:15:09.892+01:00","length":1476,"duration":1476,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/63-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/63-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/63-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/63-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-63-fine-spatial-scale-modelling-of-trentino-past-forest-landscape-trentinoland-a-case-study-of-foss-application","url":"https://api.media.ccc.de/public/events/c9058144-0344-5cdd-9e8d-228d9a6443f3","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7465,"event_guid":"d2b2bdd0-36fa-5ae1-aba0-a38960010e3b","weight":1},{"event_id":7466,"event_guid":"98c0417b-cdfd-57b3-9411-14f9f465f5b9","weight":1},{"event_id":7475,"event_guid":"49a7c19c-a42e-5058-afe1-7577dd2736c9","weight":1},{"event_id":7483,"event_guid":"54f0806e-4257-53c6-a558-e336ee584bb5","weight":1},{"event_id":7484,"event_guid":"b4d6c8c6-688b-5273-aa8f-a2044128ac13","weight":1},{"event_id":7498,"event_guid":"b197164d-0898-54b9-9348-e8d76b0efb91","weight":2},{"event_id":7504,"event_guid":"c54aa667-78de-55fb-85e7-60f2eaffd2a4","weight":3},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":3},{"event_id":7552,"event_guid":"4c2f4b81-1316-502d-870c-dc39567b782e","weight":1},{"event_id":7553,"event_guid":"9f0999f8-6941-5308-b1a8-f094c738245f","weight":1},{"event_id":7560,"event_guid":"fb1d6f2b-e06d-5bfb-9ecb-0768ed3a2fb0","weight":1},{"event_id":7571,"event_guid":"ff3f8976-451e-5f00-bc69-fb2dea80b3bb","weight":1},{"event_id":7579,"event_guid":"0112454d-62b2-5132-8971-73c7fdb972d0","weight":1},{"event_id":7584,"event_guid":"41e880ab-ca8a-5a40-aeeb-4b75fb3a94d3","weight":1},{"event_id":7623,"event_guid":"d7305220-5dac-5581-bf1b-14e735c39756","weight":1},{"event_id":7624,"event_guid":"69079f64-448d-55b5-9cb3-7089547c370d","weight":2},{"event_id":7630,"event_guid":"2922816b-f00a-5fc1-97e6-69df1a0c98ab","weight":1},{"event_id":7638,"event_guid":"6cef82f8-4f16-5fcd-adf6-aae52595dcfa","weight":1},{"event_id":7650,"event_guid":"eb077a88-d0d1-5a87-bc50-68bacdeaf135","weight":2},{"event_id":7652,"event_guid":"e04c27d0-8ff8-5bf4-b932-34db4e4fdf5b","weight":1},{"event_id":7665,"event_guid":"f1f4f54c-e816-573f-a05d-7973f9f5d48e","weight":1},{"event_id":7686,"event_guid":"32b1eb85-fc7e-50f8-9551-94bbb22873cf","weight":1},{"event_id":7689,"event_guid":"6a5482fd-2b09-5bea-bea5-b48ba7e33cf3","weight":2},{"event_id":7695,"event_guid":"5df0ebe1-cfe2-54c4-a0c8-40e35a6de826","weight":1},{"event_id":7708,"event_guid":"f41c767d-1f3d-5e46-a477-1a9dde63e146","weight":2},{"event_id":7709,"event_guid":"936a0a3d-27d2-5bb7-a59a-336837047e72","weight":1},{"event_id":7715,"event_guid":"664da34a-88d9-57c5-8b88-cdbfca55029b","weight":2},{"event_id":7732,"event_guid":"771fc01c-25ee-5202-abbe-0b993a5e7ace","weight":1},{"event_id":7736,"event_guid":"61205921-df6b-5dff-902b-9d757f719602","weight":2},{"event_id":7748,"event_guid":"753ef9d6-c39e-5cdb-88c5-1ebe4760f70a","weight":2},{"event_id":7749,"event_guid":"5117b85e-052d-5b96-bcc3-f14e953b887a","weight":1}]},{"guid":"a3427cdb-d2e7-5f6d-bd1e-536a2f9f34fb","title":"The best of both worlds: Using open and closed source s/w to manage Transportation Networks and associated LRS","subtitle":null,"slug":"bucharest-439-the-best-of-both-worlds-using-open-and-closed-source-s-w-to-manage-transportation-networks-and-associated-lrs","link":"https://talks.2019.foss4g.org/bucharest/talk/LYXPTN/","description":"Imagine having a leading-edge application that manages Transportation Networks.

It makes use of FOSS software (Python, R, GDAL) for all data processing steps. Our work in the project focuses on two aspects: land cover fraction mapping at the continental level (Africa) and yearly map updating.\nFor land cover fraction mapping, to select the most appropriate method, a number of machine learning algorithms were run on over 300 covariates: Proba-V image time series (100m, 4 bands), DEM, soil and climate properties. Random Forest performed the best with RMSE=16.6, MAE=9.2, and 68±4% overall accuracy.\nTo generate yearly map updates, we investigated different vegetation indices and break detection methods, as well as their scalability to big data (MODIS time series, 2009-2019). All change detection methods tended to overestimate change. Proba-V Mission Exploitation Platform Spark cluster was used to run chunked jobs in parallel.\nIn the future, CGLS aims to move to Sentinel-1+2 for land cover classification and Landsat 5+7+8 for change detection for higher spatial and spectral resolution, but that makes big data challenges even bigger.\n\nNone","original_language":"eng","persons":["Dainius

At EOX among other things we create global satellite basemaps (https://s2maps.eu), therefore we understand that saving resources increases reliability of any tool, product or data. While working on the basemaps we found out we can derive new products for our customers: multispectral cloud free mosaics (https://cloudless.eox.at).\n\nUsually, a user is confronted with a large number of single scenes or products with varying degrees of quality and cloud coverage. To make this first step of using EO data easier a good extraction method and data bundling becomes more and more important to make it easier to access Earth observation data without having to dig through the archives.

It has primarily been fulfilling the various special needs of its developers. From an outsider's perspective, it is an amazingly rich patchwork of features. However, some are deeply hidden in numerous layers of user interface elements, requiring intense training for getting used to. Others are only accessibly through APIs, requiring not only training but also programming skills.\n\nBeing confronted with QGIS as professional users on a regular basis, we thought about what would make working with QGIS more attractive. What if QGIS has a pleasant, coherent theme, including not only colors but also icons? What if QGIS had the ability to store workbench configurations? What if QGIS had dedicated interface configurations for specific workflows? What if much more of the API's functionality was accessible through the GUI in a well-organized way? How could QGIS work in a useful manner with ribbons? How could the incredible amount of dialogs be tamed into tabs?\n\nWe demonstrate (live) a series of user interface experiments - all of which are or will be [available online](https://github.com/qgist) as plugins or patch sets.

Database consists of spatially oriented data as well as attribute data collected from owners of electronic communications infrastructure and different public institutions e.g. The surveying and mapping authority of the RS, Ministry of the interior, etc. Combining these data gives AKOS complete overview of the networks availability and population/homes coverages by various broadband and mobile networks. Database is being updated every few months with newer data, so we can monitor development of broadband services by years and by owners of communications infrastructure. AKOS launched an open portal to enable public access to the part of these data for interested stakeholders in 2019.

That is why we have been experimenting with solutions to make use of WebGL, mixing rendering and maintaining interaction.\nIn order to be able to render scientific data (as read by geotiff.js) we have developed plotty (https://github.com/santilland/plotty). This tool allows us to quickly colorize and render the data using a shader, making it possible to create interactive and explorable animations.\nFor further data analysis, such as evolution curves through time or larger and complexer plots we have been working on graphly (https://github.com/EOX-A/graphly). In this case for us it was imperative to maintain complex interactivity while using rendered images. This was achieved by combining a second \ncanvas which keeps unique identifier colors for the objects.\nWe would like to present our concepts and experiences of the developed tools.\n\nNone","original_language":"eng","persons":["Lubomír Bucek","Daniel Santillan

INSPIRE and OpenStreetMap data: how to make the most out of the two worlds","subtitle":"","slug":"bucharest-102-comparing-inspire-and-openstreetmap-data-how-to-make-the-most-out-of-the-two-worlds","link":"https://talks.2019.foss4g.org/bucharest/talk/7VGNQK/","description":"\u003cp\u003eWith the exponential growth of the variety, heterogeneity and volumes of geospatial data, a wide range of actors have increased their need to combine information from multiple sources such as private, crowdsourced and public sector repositories. The purpose of this study is to compare two sources currently relevant for Europe: INSPIRE and OpenStreetMap (OSM). In doing so, we start with a brief overview of the two data sources, outlining similarities and differences as well as pros and cons for data users. In force since 2007, INSPIRE is the Directive aiming to create a European (EU) Spatial Data Infrastructure (SDI) to be used for environmental policies. The Directive requires EU Member States (MS) to publish geospatial content falling under 34 cross-sectoral categories (themes) according to a Service-Oriented Architecture (SOA) approach based on ISO and OGC standards. On the other hand, OSM is the leading geospatial crowdsourcing project. Born in 2004 and counting more than 1 million active contributors, the project has produced a worldwide, large-scale geospatial database. In addition to their different approach (legislative, top-down vs. community-based, bottom-up), INSPIRE and OSM feature a number of technical differences. While OSM data is structured around a flat data model with attributes encoded as simple key/value pairs, defined and maintained by the OSM community in a flexible wiki environment, INSPIRE features complex data models for each of the 34 themes which have been rigorously defined and are maintained by the European Commission through a constant dialogue with INSPIRE stakeholders. Consequently, while INSPIRE proposes specific data formats for increased interoperability, OSM data can be retrieved into a variety of GIS-friendly encodings as well as through dedicated Application Programming Interfaces (APIs) which increase their reuse and the development of third-party applications. From a legal point of view, the open access license of OSM (available under the Open Database License) further facilitates the re-use of the data as well as the production and distribution of derived products at any spatial scale. Instead, being built on top of individual national infrastructures, INSPIRE data sets are available under a variety of different licenses, which overall may hinder the full usability of the infrastructure. Finally, whilst INSPIRE is by definition an authoritative source of quality-certified data, OSM quality can only be ensured by the very nature of its crowdsourced approach; nevertheless it has been proven in some cases to be comparable, if not even better, than authoritative sources. The paper will further develop this comparison by detailing the aforementioned elements on concrete use cases addressing specific EU MS and thematic data sets and discussing how to make the most out of the two sources. An analysis of available FOSS4G solutions to access, visualize, analyse and process INSPIRE and OSM data will be also provided.

impact of land use and land use change and forestry (LULUCF) on soil organic carbon (SOC) stocks and greenhouse gas (GHG) emissions is important for both national GHG inventory reporting and worldwide strategy to offset GHG emissions. Within the Irish Soil Organic carbon and Land Use Mapping (SOLUM) project, Eurostat’s Land Use/Cover Area frame Survey (LUCAS) of 2015, LUCAS soil survey of 2009, and ancillary national open data were employed in an analytical GIS framework to develop spatially integrated soils and land use dataset specific for Ireland.\nIn order to capture dominant Irish land uses that are not included in the EU wide LUCAS survey, the LUCAS dataset was reclassified to grassland intensification and management for IPCC reporting purposes using a formal, semi-automated, interpretation key approach. All types of land use were ascribed to a soil label using the open source Soil Information System (SIS) for Ireland and other ancillary geospatial data, thus generating LUSII, Land Use and Soil Inventory for Ireland.\nThus LUSII builds on an existing EU wide Open Data set with local knowledge and GIS analysis to create a new more applicable national dataset.\n\nNone","original_language":"eng","persons":["Gabriela

Functions for UN Field Operations – UN Open GIS: Spiral 3 Geo-Analysis","subtitle":null,"slug":"bucharest-78-geo-analytic-functions-for-un-field-operations-un-open-gis-spiral-3-geo-analysis","link":"https://talks.2019.foss4g.org/bucharest/talk/PRXB9V/","description":"As the United Nations (UN) is a complex organization carrying out divers tasks in the world, most functions for an enterprise GIS are required. In order to support the requirements from the UN, the UN Open GIS Initiative was founded in 2016 with goals to provide GIS solutions for the UN based on open source software. The working group 3 of the initiative, named Spiral 3, aims to develop and deliver geo-analytic functions to the UN. In particular, a number of geo-analytic functions are developed by Spiral 3 to support field operations such as UN peace keeping operation. \nIn this paper, we present a development use-case of geo-analytic functions for the UN, which is composed of four steps; analysis of requirements and functional specification, definition of development environment and system architecture, system development and test, and documentation of user manual and education materials. First, a comprehensive study on UN operations has been carried out, which covers the following tasks; situational awareness, security operations, military operations, protection of civilians, human rights violation investigation, epidemiological analysis, mission’s support and logistics operations, electoral support, disarmament, demobilizations and reintegration program, and humanitarian response operations. From this study, we derived 26 primitive geo-analytic functions. The users of geo-analytic functions for these tasks include mostly officers at field offices and geo-analysis experts at mission headquarters. \nSecond, the system development environment was determined as Java using GeoTools for the compatibility and portability. The geo-analytic functions were developed as a plug-in of uDig, which is a Java-based open source desktop GIS. It means that the preparation and pre-processing of data for geo-analysis and the visualization of the analysis are supported by uDig. Third, an experiment of the developed system was performed with a scenario of Ebola virus spread. It shows that the system properly supports the field operations of Ebola virus spread. The experiment also shows the strength and weakness of the developed geo-analysis functions in comparison with commercial GIS.

Its economic activities increasingly influence countries beyond its own borders and dominate global economic growth. The analysis of the shifting axis uses global trade data that countries report through the Harmonised Commodity Description and Coding System (HS-Codes). The shift of power towards China is evident when the spatial mean of some 220 globally traded commodities is calculated for which data is available. Other geo-(statistical) indicators further quantify and visualise China’s growing economic power while other economic centres cannot keep up with this pace or even decline in importance.\n\nNone","original_language":"eng","persons":["Arne Schumacher"],"tags":["bucharest","384","2019","General"],"view_count":99,"promoted":false,"date":"2019-08-30T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2025-05-09T09:15:05.273+02:00","length":1894,"duration":1894,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/384-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/384-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/384-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/384-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-384-the-shift-of-trade-powers-understanding-china-s-growing-importance-in-global-economic-activity-with-foss-technologies","url":"https://api.media.ccc.de/public/events/361e8802-42c9-542d-8fcd-05647efe3d84","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7472,"event_guid":"d021f555-141a-58f6-a21b-a787b1c84188","weight":1},{"event_id":7491,"event_guid":"7ce19c2c-7bc3-5ba7-b454-b383a7c58c6c","weight":1},{"event_id":7521,"event_guid":"95aa7cdb-5057-54aa-9dbc-511e4ee508c4","weight":1},{"event_id":7536,"event_guid":"9f921eab-53c5-5ce7-9489-45a586162248","weight":1},{"event_id":7552,"event_guid":"4c2f4b81-1316-502d-870c-dc39567b782e","weight":1},{"event_id":7555,"event_guid":"a641fc9b-2eb6-5580-8acc-4236e227de4e","weight":2},{"event_id":7579,"event_guid":"0112454d-62b2-5132-8971-73c7fdb972d0","weight":1},{"event_id":7585,"event_guid":"3e149633-f405-5e9b-850c-b0934537b6d8","weight":1},{"event_id":7595,"event_guid":"1b45aaaa-70dc-5f27-8b7b-64dc0fe409a5","weight":1},{"event_id":7607,"event_guid":"d0794cae-d707-584c-8879-6c438a603486","weight":1},{"event_id":7619,"event_guid":"21ffa487-5dfd-57d3-acce-8fd048ead7cf","weight":1},{"event_id":7624,"event_guid":"69079f64-448d-55b5-9cb3-7089547c370d","weight":1},{"event_id":7630,"event_guid":"2922816b-f00a-5fc1-97e6-69df1a0c98ab","weight":1},{"event_id":7641,"event_guid":"d5b00dcc-d898-5a3a-bc8f-8e62d492bf4e","weight":1},{"event_id":7647,"event_guid":"39de1ec8-9848-55e3-a2c6-99d40d5f2d97","weight":1},{"event_id":7655,"event_guid":"3b5c1185-42c2-5e87-b4ba-779be1a3297b","weight":1},{"event_id":7656,"event_guid":"cdcc0bac-ebad-566c-b691-c54010212a86","weight":1},{"event_id":7657,"event_guid":"13347d51-f447-50a0-86b3-1e0833dedc68","weight":1},{"event_id":7659,"event_guid":"81f32156-c1c3-5ee8-8fec-e5800350f677","weight":1},{"event_id":7660,"event_guid":"17585226-58b0-51da-a3b6-3c41ff51db2c","weight":1},{"event_id":7661,"event_guid":"afb75703-96a4-5546-b1fa-493154ef35ae","weight":1},{"event_id":7662,"event_guid":"a8fbf537-cbe1-5f17-aa73-97d64132f660","weight":1},{"event_id":7663,"event_guid":"1b265f5f-a622-52e0-a2a4-88105aa09aba","weight":1},{"event_id":7664,"event_guid":"bc480eaa-8db8-54d0-bc53-32a81725f2d9","weight":1},{"event_id":7665,"event_guid":"f1f4f54c-e816-573f-a05d-7973f9f5d48e","weight":1},{"event_id":7669,"event_guid":"7627a093-69e4-5c72-b8b5-0f05c27ce815","weight":1},{"event_id":7686,"event_guid":"32b1eb85-fc7e-50f8-9551-94bbb22873cf","weight":1},{"event_id":7688,"event_guid":"9884da36-043b-5822-920a-f125c93faf74","weight":1},{"event_id":7692,"event_guid":"3c0ea464-ce0e-5676-a977-075148d7bbdd","weight":1},{"event_id":7694,"event_guid":"05466dda-8c63-57a3-a1ff-ebeff2abaa92","weight":1},{"event_id":7695,"event_guid":"5df0ebe1-cfe2-54c4-a0c8-40e35a6de826","weight":1},{"event_id":7705,"event_guid":"c2575631-1db8-5188-b684-d153774a171e","weight":1},{"event_id":7710,"event_guid":"9bce8e1a-0dc8-5c82-977c-23dccd115e89","weight":1},{"event_id":7729,"event_guid":"9d030aa8-27aa-509b-913f-ee9eff97257b","weight":1},{"event_id":7733,"event_guid":"0ba5c644-2353-5225-972e-6e3958f74f3e","weight":1},{"event_id":7735,"event_guid":"87cfd947-401b-57a9-9ea2-4f6a76b8fdd6","weight":1}]},{"guid":"3bf3bca5-f60f-5af0-b8a8-8a0a229b234b","title":"ZOO-Project: News about the Open WPS Platform","subtitle":null,"slug":"bucharest-340-zoo-project-news-about-the-open-wps-platform","link":"https://talks.2019.foss4g.org/bucharest/talk/NFT3JC/","description":"ZOO-Project is a WPS (Web Processing Service) platform which is implemented as an Open\nSource project and following the OGC standards, it was released under an MIT/X-11 style license and\nis currently in incubation at OSGeo.

It is relevant for each aspect of data publication; data, transformations, service and metadata. The review phase should be as complete as possible (including INSPIRE/OGC/QOS validation) so there will be no surprises when making the resource widely available. \n\nGeoNetwork has had a workflow module to allow users to review a record before it becoming public for a long time, however the functionality was a bit hidden and had some challenges. This summer we're landing a 5 years old feature branch in GeoNetwork to improve this aspect of the application. The workflow, if configured, is brought more upfront and a mechanism has been added to allow to work in a draft version, before the approved copy is replaced.\n\nThis branch has been extensively tested by some of our users in recent years. From their experiences we’ll highlight some of the additional benefits of this module. The workflow mechanism can also be used to trigger publication of datasets in external components, such as Docker or GeoServer.\n\nNone","original_language":"eng","persons":["François Prunayre","Antonio Cerciello","Paul van Genuchten"],"tags":["bucharest","255","2019","General"],"view_count":54,"promoted":false,"date":"2019-08-29T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2023-11-26T23:00:03.185+01:00","length":1055,"duration":1055,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/255-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/255-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/255-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/255-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-255-metadata-workflow-history-and-draft-in-geonetwork","url":"https://api.media.ccc.de/public/events/49724c62-af53-50b0-87ee-07cee5c4cdfb","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7487,"event_guid":"6f1b8b15-b44a-592c-b3e9-96bd9e0fbce3","weight":3},{"event_id":7495,"event_guid":"bffc8bd9-0df8-5543-8c24-254c05092bbd","weight":3},{"event_id":7499,"event_guid":"de560d64-70a3-518c-b12d-5b639a1c7b97","weight":2},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":1},{"event_id":7551,"event_guid":"390f46cd-b632-5bbd-b24c-463606723436","weight":3},{"event_id":7554,"event_guid":"20bb70f9-e0ab-5d46-9e99-71cd75e04251","weight":3},{"event_id":7575,"event_guid":"bcca12c5-309f-588b-a67e-c5f1fc31f998","weight":2},{"event_id":7649,"event_guid":"b60859dd-b7b5-5537-acaa-fd695b7cd29a","weight":10},{"event_id":7668,"event_guid":"4b718f1b-6e92-5ed0-a0bf-99f09fd5e873","weight":2},{"event_id":7685,"event_guid":"76554f37-f382-50da-a02a-3656b5a70ed2","weight":2},{"event_id":7687,"event_guid":"a0e3a9de-ed9b-5cc6-8a5b-c9d37476c433","weight":1},{"event_id":7706,"event_guid":"2931c54a-5a66-5024-87ea-4c283dc0f8f2","weight":1},{"event_id":7732,"event_guid":"771fc01c-25ee-5202-abbe-0b993a5e7ace","weight":1},{"event_id":7757,"event_guid":"08e7e90e-7da4-524d-8875-b38d23b6c1cf","weight":1}]},{"guid":"753ef9d6-c39e-5cdb-88c5-1ebe4760f70a","title":"The case of PULSE: fostering sustainable environments using geodata with a participatory approach","subtitle":null,"slug":"bucharest-396-the-case-of-pulse-fostering-sustainable-environments-using-geodata-with-a-participatory-approach","link":"https://talks.2019.foss4g.org/bucharest/talk/J3QSS7/","description":"PULSE (Participatory Urban Living for Sustainable Environment) is an EU-financed project that aims to develop a set of models and technologies to predict and manage public health problems in cities and promote health. It follows a participatory approach where citizen provide data through personal devices, that are integrated with information from heterogeneous sources: open city data, health systems, urban sensors and satellites. The project deals with various issues concerning air quality, lifestyle and personal behavior and it aims to investigate the correlations between the exposure to atmospheric pollutants, the citizen habits and the health of the citizen themselves, focusing on Asthma and T2 diabetes.PULSE is being implemented in 5 major cities.\nThe presentation will concentrate on the key geospatial aspects of the platform, implemented using FOSS, highlighting issues and challenges. It will describe the most relevant components, such as satellite data processing, deployment of sensors, management of acquired spatial data, WebGIS and Dashboard tools to provide spatiotemporal visualization and analysis, the integration of models, the definition of relevant index to connect epidemiologic data with spatiotemporal

By removing the need for a tile server, GeoRasterLayer can save users a lot of effort and money, but building the plugin didn't come without its challenges.  This talk walks through the algorithm for visualizing large GeoTIFF files on a web map while boosting performance.  Specifically it will discuss the algorithm implemented for the Leaflet plugin, but the lessons learned can apply to any web mapping library.

What I would like to bring on FOSS4G 2019 is an experimental approach which integrates NLP with mapping system. Just for convenience, I call this approach “document-mapping”. In this approach, documents are plotted according to their similarities: in other words, similar documents are plotted within close proximity, and vice versa. This approach can be done by several NLP based algorithms. As a result of the processing, XY coordinates are attached with each document. This approach will show us lots of possibilities, converting qualitative data-sets into quantitative ones. For example, we can evaluate the impact on a specific article or an opinion not only by numeric data but also visualized map with the similarity-distance. I attached an example using twitter data-sets. Another possibility I would like to introduce is its application for regional masterplans. I am currently trying to analyze a transition of cities and achievements of the city plans by using this idea. This attempt is still on a progress, and hopefully I would like to present this result in August.\n\nNone","original_language":"eng","persons":["Eita

urban planning, environmental management, transport optimization, risk assessment, etc. The LC data currently available in the Walloon region in Belgium date back over a decade and an update was thus needed. The regional administration decided to launch a research project to develop a robust, automatized, scalable and reproducible method for creating these data, principally based on the available VISNIR orthoimagery at 0.25 m resolution, as well as height information derived through photogrammetry.The ultimate aim of the project is not only to provide recent (2018) maps, but also to elaborate a method that would make it easier for the region to reproduce such data at higher temporal frequency than in the past. The size of the data set (several TB) also provoked a specific focus on scalability while ease of application for a regional administration was another priority.Whereas in urban areas an object-based (OBIA) approach has been the privileged path in the last years as it allows taking into account shape information relevant for the characterization of man-made constructions, such an approach has its limits in the rural and more natural areas the structure of which does not fit as well into the OBIA paradigm, thus calling for a pixel-based approach. In addition, many of the more natural land cover classes have temporal profiles which cannot be detected in a one-date orthoimage. We therefore decided to also analyze Sentinel 1 and 2 data in order to profit from their higher spectral and temporal resolution.All methods were trained using existing regional databases. In a second step, we combined the different LC classification results by fusioning them into one high-accuracy (over 90% OA) product, using a series of different approaches ranging from rule-based to machine learning, passing by more statistical techniques such as Bayesian fusion.\n\nThe research teams involved have a long tradition of working with FOSS in image analysis and the choice for a purely FOSS approach was quite obvious and clearly encouraged by the regional administration. Complementary experiences working, for one, with Orfeo Toolbox, and for the other with GRASS GIS, allowed the combination of these different software in the overall framework. This paper will present the details of the respective LC classification chains, including some improvements to the software that happened during the process. Individual LC results as well as results of the different approaches tested for fusioning the different LC products will allow to highlight the advances made, but also some difficulties encountered during the work. In a final section we will present future steps of the work, such as the passage from LC to LU based on alphanumeric databases and the use of LC landscape metrics.\n\nNone","original_language":"eng","persons":["Eléonore Wolff","Pierre Defourny","Benjamin Beaumont","Céline Bassine","Julien Radoux","Taïs Grippa","Moritz Lennert"],"tags":["bucharest","66","2019","Academic"],"view_count":85,"promoted":false,"date":"2019-08-28T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2024-07-12T17:15:02.650+02:00","length":1602,"duration":1602,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/66-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/66-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/66-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/66-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-66-creating-wallonia-s-new-very-high-resolution-land-cover-maps-combining-grass-gis-obia-and-otb-pixel-based-results","url":"https://api.media.ccc.de/public/events/437a912d-ff97-5431-a0d3-7d7735f3b14d","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7464,"event_guid":"a5a5b7b3-060a-582a-b1b2-f626a681e79b","weight":2},{"event_id":7465,"event_guid":"d2b2bdd0-36fa-5ae1-aba0-a38960010e3b","weight":2},{"event_id":7467,"event_guid":"df17d333-e410-5e1f-a31c-42805b52b53c","weight":2},{"event_id":7469,"event_guid":"c0174aef-c7a6-5d21-8dfe-e592c5a4eff3","weight":2},{"event_id":7483,"event_guid":"54f0806e-4257-53c6-a558-e336ee584bb5","weight":2},{"event_id":7484,"event_guid":"b4d6c8c6-688b-5273-aa8f-a2044128ac13","weight":1},{"event_id":7488,"event_guid":"0a3e23aa-d593-58cd-a3a1-7991e3a3a064","weight":2},{"event_id":7501,"event_guid":"a4aa4222-f2ca-5e0c-94f6-4c7a3595d1a2","weight":2},{"event_id":7505,"event_guid":"5ac07c14-e2f1-5cba-a86f-047443848af5","weight":2},{"event_id":7510,"event_guid":"ab6c65d7-f9df-563f-b9bb-e36c128e9ab4","weight":2},{"event_id":7518,"event_guid":"8773035b-d16c-5cf3-902d-43abc7e5dab7","weight":2},{"event_id":7520,"event_guid":"2e1e926d-3eaa-5fa1-83b3-1a8e001df0c6","weight":1},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":1},{"event_id":7545,"event_guid":"726938bf-af52-5c0e-9198-0053eba64726","weight":4},{"event_id":7548,"event_guid":"8ca1b4b6-ee0c-5102-ab95-a978cd3b4d8c","weight":2},{"event_id":7550,"event_guid":"53494dbe-b19b-5e77-a2d1-9cb5a6d5447d","weight":2},{"event_id":7552,"event_guid":"4c2f4b81-1316-502d-870c-dc39567b782e","weight":1},{"event_id":7572,"event_guid":"fb951433-b271-5884-b370-a8ef56393406","weight":3},{"event_id":7579,"event_guid":"0112454d-62b2-5132-8971-73c7fdb972d0","weight":4},{"event_id":7582,"event_guid":"95c65e38-a93e-5306-a9c6-b1cdc197bb58","weight":2},{"event_id":7584,"event_guid":"41e880ab-ca8a-5a40-aeeb-4b75fb3a94d3","weight":2},{"event_id":7606,"event_guid":"c0ebaf1b-03d8-53f4-81d1-b5b306e93c60","weight":2},{"event_id":7608,"event_guid":"13e2ef4d-8375-580b-a797-c54a85faa0aa","weight":2},{"event_id":7612,"event_guid":"20bb8f65-038d-5e73-bba1-186f5b40f548","weight":1},{"event_id":7619,"event_guid":"21ffa487-5dfd-57d3-acce-8fd048ead7cf","weight":2},{"event_id":7623,"event_guid":"d7305220-5dac-5581-bf1b-14e735c39756","weight":2},{"event_id":7624,"event_guid":"69079f64-448d-55b5-9cb3-7089547c370d","weight":3},{"event_id":7626,"event_guid":"227ae37a-41aa-53d7-944a-2e9b7c8d99a7","weight":2},{"event_id":7649,"event_guid":"b60859dd-b7b5-5537-acaa-fd695b7cd29a","weight":1},{"event_id":7652,"event_guid":"e04c27d0-8ff8-5bf4-b932-34db4e4fdf5b","weight":1},{"event_id":7670,"event_guid":"87692512-45dd-5b7b-9456-62d1a04a185e","weight":2},{"event_id":7673,"event_guid":"89f564bf-e743-5086-a372-478a49b0d7ce","weight":3},{"event_id":7675,"event_guid":"9e54b705-cdd9-5485-8bec-d392c97aee70","weight":2},{"event_id":7713,"event_guid":"14dfde19-5a7a-59ee-8470-e75266353678","weight":2},{"event_id":7721,"event_guid":"9462ccbb-1601-5d12-8756-5e11e3134112","weight":2},{"event_id":7726,"event_guid":"5fabfcb3-0d99-553b-a6f8-5a6119513afc","weight":2},{"event_id":7749,"event_guid":"5117b85e-052d-5b96-bcc3-f14e953b887a","weight":2},{"event_id":7756,"event_guid":"c4299de5-e39e-576d-93bb-7ae47fee42af","weight":2}]},{"guid":"41e880ab-ca8a-5a40-aeeb-4b75fb3a94d3","title":"Remote Sensing Analysis for Urban Research at Scale","subtitle":null,"slug":"bucharest-116-remote-sensing-analysis-for-urban-research-at-scale","link":"https://talks.2019.foss4g.org/bucharest/talk/GBJW3P/","description":"Image classification of urbanization processes require reference data either for training or for validation.

Being a community-driven project, it offers geospatial analysis, earth observation, time series processing and visualization. It supports large raster files (billions of cells), vector topology, and coupling with SQL databases.\n\nIn our presentation we'll give an overview of the latest improvements. The algorithms for interpolation, solar radiation, water flow, and sediment transport have been parallelized. Experimental features include concave hull, vector algebra, point cloud import, DEM fusion and blending, object-based classification, Sentinel data processing, and spatio-temporal algebra. Furthermore, pest spread and urban growth modeling are now available.\n\nImportantly, Python 3 support has been added. Raster storage now benefits from new ZSTD compression. GRASS GIS supports GDAL up to v2.5 and PROJ up to v6. Easy cloud deployment is offered with ready-to-use docker images and an improved test coverage along with continuous integration.\n\nThe code development will move to GitHub, including the issues and source code branches since 1987.

Urban Design with Open Source Geospatial Technologies","subtitle":null,"slug":"bucharest-52-supporting-urban-design-with-open-source-geospatial-technologies","link":"https://talks.2019.foss4g.org/bucharest/talk/BXLBUU/","description":"The role of urban designers is to shape the physical features of a city with the goal of making the city functional and pleasant to live in. For this, the urban designer has to gather information about the current situation, design improvements, and communicate these to stakeholders. The use of space and the spatial relationships between physical features play a significant role in urban design, therefore much of the information that is collected and manipulated is georeferenced. In this paper we review and evaluate open source geospatial technologies that can be used for the collection, storage, manipulation and visualization of geospatial data in urban design projects. Based on this, an open geospatial toolbox for urban design projects is presented.\n\nWe followed a scenario-based approach for collecting the requirements. Three researchers were asked to explain how they collect and use data for their urban design projects. Their backgrounds were in spatial planning and architecture. The first scenario involves an urban designer who is requested to guide and advise the local municipality on improvements in a neighborhood that has become dilapidated over time, and therefore unsafe. In the second scenario, the aim was to identify crime hotspots in a neighborhood and to propose preventative crime measures through environmental design. \n\nBy analyzing the scenarios, we determined both functional and non-functional requirements, and categorized them into requirements related to data collection, data storage and management, and data visualisation respectively. A set of open source geospatial technologies were evaluated against these requirements. Tools were evaluated against requirements relevant to a category, e.g. for data storage and management, the user should be able to upload geospatial data, upload newer versions of the data, create and edit metadata about the data, and share the data in various formats using web services. Furthermore, the evaluation results show how tools meet individual requirements, i.e. tools that meet only one of several requirements were not excluded. The resulting open geospatial toolbox is modular, allowing urban designers to swap out a tool in a category for another one in that category, or swap out a tool that meets one requirement for another tool that meets that requirement.\n\nEach of the evaluated tools fulfilled the functional requirements to some degree; the real difference emerged from the non-functional requirements, such as perceived usability for novice users and documentation or support available. The results in this paper are based on requirements of urban designers, but are equally applicable for others who collect data at the neighbourhood level. Future work will focus on aspects of provenance for preserving and making data collected for urban design studies available for longitudinal studies.\n\nNone","original_language":"eng","persons":["Serena Coetzee","Megan Haynes","Victoria Rautenbach"],"tags":["bucharest","52","Academic"],"view_count":27,"promoted":false,"date":"2019-08-30T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2024-05-22T18:45:06.363+02:00","length":1391,"duration":1391,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/52-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/52-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/52-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/52-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-52-supporting-urban-design-with-open-source-geospatial-technologies","url":"https://api.media.ccc.de/public/events/1e986309-98ba-5840-b70e-300ff54d78bc","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7475,"event_guid":"49a7c19c-a42e-5058-afe1-7577dd2736c9","weight":1},{"event_id":7501,"event_guid":"a4aa4222-f2ca-5e0c-94f6-4c7a3595d1a2","weight":3},{"event_id":7505,"event_guid":"5ac07c14-e2f1-5cba-a86f-047443848af5","weight":1},{"event_id":7510,"event_guid":"ab6c65d7-f9df-563f-b9bb-e36c128e9ab4","weight":1},{"event_id":7519,"event_guid":"33229e10-d954-564b-bb6f-f48e5b5d3882","weight":2},{"event_id":7524,"event_guid":"f58c39cb-2250-51b5-8902-d52f713c934b","weight":1},{"event_id":7533,"event_guid":"bff8e480-f2e6-5fb7-a945-fed5e6b06f77","weight":1},{"event_id":7553,"event_guid":"9f0999f8-6941-5308-b1a8-f094c738245f","weight":1},{"event_id":7556,"event_guid":"c9b9934c-1cec-518c-ab2f-6a70ee5622f0","weight":1},{"event_id":7568,"event_guid":"7a848633-35e2-5b06-962e-c9cb71cf9762","weight":1},{"event_id":7579,"event_guid":"0112454d-62b2-5132-8971-73c7fdb972d0","weight":3},{"event_id":7597,"event_guid":"5250fc42-6c79-5499-9029-87009757e5f5","weight":1},{"event_id":7627,"event_guid":"1afdcbac-7132-5769-8368-712bf4a8163a","weight":1},{"event_id":7651,"event_guid":"84c94e48-3002-55f3-9d4a-c66f5d2e4198","weight":1},{"event_id":7656,"event_guid":"cdcc0bac-ebad-566c-b691-c54010212a86","weight":1},{"event_id":7672,"event_guid":"1c58bd3e-15f6-51a3-af44-9d6a75f31556","weight":1},{"event_id":7676,"event_guid":"d77d9253-da6c-521a-ad5e-ff17c419cbea","weight":1},{"event_id":7681,"event_guid":"a1326956-88be-5af4-b747-5cefc95e8232","weight":2},{"event_id":7694,"event_guid":"05466dda-8c63-57a3-a1ff-ebeff2abaa92","weight":1},{"event_id":7715,"event_guid":"664da34a-88d9-57c5-8b88-cdbfca55029b","weight":1},{"event_id":7724,"event_guid":"583daa21-2358-57db-8ee9-d7e1572e4c8f","weight":2},{"event_id":7726,"event_guid":"5fabfcb3-0d99-553b-a6f8-5a6119513afc","weight":1},{"event_id":7746,"event_guid":"d6b3b1a7-ed40-50da-a4ef-43775cad7688","weight":2},{"event_id":7756,"event_guid":"c4299de5-e39e-576d-93bb-7ae47fee42af","weight":2}]},{"guid":"7347a409-8f11-53a7-b855-39fcf0d8c2ae","title":"Design and development of the UN Vector Tile Toolkit","subtitle":null,"slug":"bucharest-37-design-and-development-of-the-un-vector-tile-toolkit","link":"https://talks.2019.foss4g.org/bucharest/talk/3DGWDJ/","description":"The UN Open GIS Initiative is catalyzing the development of an open community for basemap vector tile providers. The Initiative promotes the UN Vector Tile Toolkit, a package of open source tools designed to enable public basemap providers, such as the United Nations geospatial information services or governmental mapping organizations, among others, to deliver their basemap vector tiles leveraging the latest web map technologies. The toolkit provides a set of Node.js open source scripts designed for developers to use in conjunction with existing and proven open-source vector tile software (such as [Tippecanoe](https://github.com/mapbox/tippecanoe), [Maputnik](https://github.com/maputnik/editor), [Mapbox GL JS](https://github.com/mapbox/mapbox-gl-js) and [vt-optimizer](https://github.com/ibesora/vt-optimizer)). The toolkit will help organizations to produce, host, style, and optimize fast and interoperable basemap vector tiles, making them available with various application frameworks. \n\nThis paper presents the methodology followed to support the requirements from the UN Peacekeeping operations’ point of view. The significant challenges were to ensure (1) flexibility of the software so that it works with different source data, including UN mission-specific basemap data and global OpenStreetMap data, (2) automatic and continuous update of global basemap vector tiles, (3) fast vector tiles that can be used with mobile devices in the field, and (4) interoperability with existing enterprise geospatial software frameworks. \n\nWe approached these challenges by introducing \"on-the-fly vector tile schema modification\" to the Toolkit so that an agile adaptation, improvement, and optimization of the vector tile schema is possible. This method also reduces the use of temporary storage and improves the processing time by exploiting the outstanding stream processing capabilities of Node.js and Tippecanoe. We also adopted an approach to produce basemap vector tiles in modules, so that the processes to produce and deploy the vector tiles are well pipelined. This modularization approach also extended the scalability of the Toolkit by allowing parallel or even distributed production. Quantitative measurements, like in vt-optimizer, were other dominant methodology adopted in the Toolkit that enabled evidence-based performance tuning and production time reduction the vector tiles. As a result, we successfully implemented automatic and continuous updates of basemap vector tiles from a continuously updated PostGIS database. The paper also covers how the project ensured interoperability with different existing enterprise geospatial software frameworks that use less-advanced web map libraries.\n\nThe project aims to build a sustainable community of developers supporting the provision of fast and interoperable basemap vector tiles that meet the requirements of various users in the field missions and UN headquarters among others.\n\nNone","original_language":"eng","persons":["Hirofumi Hayashi","Hidenori Fujimura","Oliva Martin","Takenori SATO","Nobusuke IWASAKI","Diego Gonzalez Ferreiro","Yoichi Kayama","Yusuke Motojima","Francis Mugambi"],"tags":["bucharest","37","2019","Academic"],"view_count":63,"promoted":false,"date":"2019-08-28T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2024-11-01T09:30:04.228+01:00","length":1254,"duration":1254,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/37-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/37-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/37-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/37-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-37-design-and-development-of-the-un-vector-tile-toolkit","url":"https://api.media.ccc.de/public/events/7347a409-8f11-53a7-b855-39fcf0d8c2ae","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":6796,"event_guid":"51d3b894-e061-570d-8d94-d0ce984b37c4","weight":1},{"event_id":6812,"event_guid":"604049b2-25f5-52f1-b98a-8c7cfb08a1e8","weight":1},{"event_id":7462,"event_guid":"bc0ea171-a661-56f9-a518-e32c84bbcf8b","weight":1},{"event_id":7464,"event_guid":"a5a5b7b3-060a-582a-b1b2-f626a681e79b","weight":1},{"event_id":7478,"event_guid":"ae1cdec5-93fe-5638-a167-faa6e81cf9c6","weight":1},{"event_id":7484,"event_guid":"b4d6c8c6-688b-5273-aa8f-a2044128ac13","weight":1},{"event_id":7487,"event_guid":"6f1b8b15-b44a-592c-b3e9-96bd9e0fbce3","weight":1},{"event_id":7492,"event_guid":"f65e1c2f-8bde-5c89-a128-e113b0b9a3f6","weight":4},{"event_id":7500,"event_guid":"e72bec3a-da22-50b9-a6d6-11cedeb37917","weight":1},{"event_id":7522,"event_guid":"74922ed0-86dd-5568-98fb-6fc812852441","weight":1},{"event_id":7524,"event_guid":"f58c39cb-2250-51b5-8902-d52f713c934b","weight":1},{"event_id":7532,"event_guid":"e7956d52-af40-563e-ae3e-1df491ad6591","weight":1},{"event_id":7533,"event_guid":"bff8e480-f2e6-5fb7-a945-fed5e6b06f77","weight":2},{"event_id":7534,"event_guid":"3fc26cc4-962e-5f27-a92b-c01e86d12100","weight":1},{"event_id":7561,"event_guid":"1125685c-9fdc-5572-89c0-8bc80c7df3e0","weight":2},{"event_id":7573,"event_guid":"347ab764-8ae3-58fe-87a0-18dca9880c63","weight":1},{"event_id":7604,"event_guid":"b0001b70-6e5d-50e1-aaa4-51345e1d7a65","weight":5},{"event_id":7607,"event_guid":"d0794cae-d707-584c-8879-6c438a603486","weight":2},{"event_id":7616,"event_guid":"23bc1246-3fcb-5ce4-ac80-f8c176a25d97","weight":1},{"event_id":7618,"event_guid":"6ed3f0f2-a47f-5229-b734-0c911d11f597","weight":5},{"event_id":7632,"event_guid":"99a39bf7-5c95-5bc3-947a-55e28aa0a042","weight":1},{"event_id":7661,"event_guid":"afb75703-96a4-5546-b1fa-493154ef35ae","weight":1},{"event_id":7666,"event_guid":"5b35bf19-e251-5dea-96f1-49e2f0f88d09","weight":1},{"event_id":7667,"event_guid":"4bc8bbe5-cb04-5a2b-b441-a696be055948","weight":1},{"event_id":7674,"event_guid":"ac484924-85f6-5195-bf5b-9f689f24ef57","weight":1},{"event_id":7675,"event_guid":"9e54b705-cdd9-5485-8bec-d392c97aee70","weight":1},{"event_id":7682,"event_guid":"3da56fe5-5d22-565b-849f-591265220120","weight":4},{"event_id":7694,"event_guid":"05466dda-8c63-57a3-a1ff-ebeff2abaa92","weight":1},{"event_id":7695,"event_guid":"5df0ebe1-cfe2-54c4-a0c8-40e35a6de826","weight":1},{"event_id":7707,"event_guid":"8f9b67d8-fd60-522f-9a5b-6f0f81626e5c","weight":2},{"event_id":7709,"event_guid":"936a0a3d-27d2-5bb7-a59a-336837047e72","weight":1},{"event_id":7710,"event_guid":"9bce8e1a-0dc8-5c82-977c-23dccd115e89","weight":5},{"event_id":7729,"event_guid":"9d030aa8-27aa-509b-913f-ee9eff97257b","weight":1},{"event_id":7731,"event_guid":"dd3327f8-7f66-5844-bc78-9dede7aeb710","weight":1},{"event_id":7756,"event_guid":"c4299de5-e39e-576d-93bb-7ae47fee42af","weight":1},{"event_id":7758,"event_guid":"d7541c86-83fd-55c3-8843-f64e30b8aa55","weight":1}]},{"guid":"59c54515-13b2-5d39-9852-266d10f523fd","title":"Fast insight about the severity of hurricane impact with spatial analysis of Twitter posts","subtitle":null,"slug":"bucharest-86-fast-insight-about-the-severity-of-hurricane-impact-with-spatial-analysis-of-twitter-posts","link":"https://talks.2019.foss4g.org/bucharest/talk/CVUY3C/","description":"Social media have shown significant contribution in disaster reliefs. It could be very valuable source of the on-site information shared by the affected citizens. Particularly, Twitter is currently one of the most popular social media used for the exchange of information connected to the disasters. If this type of source is considered as a real-time crowdsourcing of crisis information, the spatial distribution of geolocated tweets related to an event can represent an early indicator of the severity of impact.  This raises a question if rapid mapping teams could use additional information from Twitter before mapping. Would it be possible to estimate the outcome, to understand the affected zones and approximate level of impact?\nThe aim of this paper is to explore the spatial distribution of the Twitter posts related to a disaster and to analyse their potential in providing fast insight regarding the impact. The focus of the analysis was on the tweets related to the hurricane Michael that happened in Florida, in the United States on October 2018. The crisis maps produced by Copernicus Emergency Management service were used as reference data and obtained results were compared with them. Copernicus EMS have produced twenty-five delineation maps over the coast of Florida. Six maps were delivered on the 11th of October and the rest of crisis maps were published on the 12th of October. The focus of this study is to explore the potential of Twitter’s crisis posts in providing information before the delivery of maps. The available message dataset consisted 8169 tweets posted from 10th until 15th October. The tweets published before the delivery of crisis maps that are inside of the crisis maps’ area, in total 30% of the available dataset, were analysed. Weights have been assigned to each tweet, on a base of the date of posting; i.e. newer posts were considered as more relevant.\nSpatial statistics have been performed with QGIS and GeoDa.

SoDUCo is a research project proposes to develop methods and models to study the evolution of the urban spatial structure in relation with social and professional practices. It allows the qualification of geo-historical sources (maps, directories, etc.), the semi-automatic extraction of the information and their (spatio-temporal) matching. Software components are all open-source and produced datasets are free to reuse.\n\nThe reconstitution of the evolution of Paris from 1789 to 1950 will be done by using two specific sets of sources: master maps (datasets mainly from the BnF (French National Libray)) and the complete series of cadastral maps which describe the evolution of road networks and urban fabric and, for the same time period, street \u0026 trade directories, which provide the socio-professional activities aor status of people localized by their addresses. \n\nThis talk will show how partners (French National Institute of Geographic and Forest Information (IGN), EHESS, National Archives and EPITA ) will build the final product of the SoDUCo project consisting in the first unified, distributed, reusable and interoperable platform to handle geo-historical sources.

It builds on top of CesiumJS - and is released under the same open-source license - while adding a responsive UI for exploring a catalog of datasets, charts and graphs, a \"splitter\" interactive comparison tool, automatic region mapping from CSV files, hooks to geoprocessing services, shareable story building, a 2D fallback based on Leaflet, and much more.\n\nIn this talk we’ll discover many of the advantages of using TerriaJS while exploring how we used open source and open standards to create the NSW Digital Twin Proof of Concept, a catalog and viewer of 3D datasets integrating live transport data, infrastructure (above and below ground), building information models, and cadastral data.\n\nTerriaJS also underpins multiple other major projects developed by CSIRO’s Data61 including Australia’s nationalmap.gov.au and the Global Risk Map - built for the United Nations Principles for Sustainable Insurance Initiative. TerriaJS is widely utilised by independent map publishers with an active chat community on gitter.im and more than 450 GitHub stars.\n\nNone","original_language":"eng","persons":["Stephen

The Open Geospatial Consortium (OGC) provides various test suites for TEAM Engine to support implementing and testing of GIS software basing on OGC standards. TEAM Engine is an OSGeo project in incubation phase.\n\nA test suite for new OGC standard WFS 3.0, which is currently a candidate standard (status of April 2019), was developed as part of OGC Testbed 14 initiative. As this standard uses completely different concepts in comparison to, for example, WFS 2.0, several conceptional questions had to be discussed and solved during implementation of test suite.\n\nThis talk presents how the new OGC standard WFS 3.0 can be validated with TEAM Engine. The process of creating a new test suite as part of OGC Testbed 14 initiative is highlighted. This includes a short introduction of WFS 3.0 standard itself. Further, current developments in TEAM Engine project are presented and an outlook is given.\n\nNone","original_language":"eng","persons":["Dirk

Come for a whirlwind tour of how these tools have been deployed by a tiny business on airborne LiDAR; photogrammetric point clouds; and huge bathymetric surveys - from raw data through to beautiful visualisations, which are also data as foundation infrastructure. Then stay for some words on how you don’t need to be a programmer to give back to the community which grows and supports these capabilities . It's part technical, part research, part business, and part provocation.\n\nNone","original_language":"eng","persons":["Adam

data, whether from cameras, satellites, drones, “go-pro”, multibeams, or sonar devices despite linked to spatial data are not embedded in traditional relational databases, rather tend to be stored separately and accessed from one or more directories. As a result, managing images turns to be problematic and leads to cases of duplication, unnecessary use of space in servers or standalone machines, laborious searching and convoluted sharing. \n\nWe will present OMERO, an open image data management platform for storing, sharing, searching and accessing multimodal imaging data. OMERO is an application originally built for biological microscopy, but which we have shown can also be used for ecological and environmental studies. OMERO also enables the integration with analytical tools such as R, ImageJ, Fiji, KNIME and Matlab, allowing scientists to derive quantitative outputs from large collections of imaging data.\n\nAfter discussing about the challenges we had to face, e.g. the ingestion of geospatial image formats, we will showcase our applications of OMERO with satellite and drone imagery, underwater photography, otholiths slides and the integration of tools for object identification, photo-id catalogues, and pattern analysis.\n\nNone","original_language":"eng","persons":["iLaria Marengo"],"tags":["bucharest","284","2019","General"],"view_count":52,"promoted":false,"date":"2019-08-30T00:00:00.000+02:00","release_date":"2019-08-30T02:00:00.000+02:00","updated_at":"2025-01-07T15:45:10.673+01:00","length":1567,"duration":1567,"thumb_url":"https://static.media.ccc.de/media/conferences/foss4g2019/284-hd.jpg","poster_url":"https://static.media.ccc.de/media/conferences/foss4g2019/284-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/conferences/foss4g2019/284-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/conferences/foss4g2019/284-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/bucharest-284-omero-an-open-source-tool-for-a-cross-disciplinary-geospatial-odyssey","url":"https://api.media.ccc.de/public/events/812560ad-8181-524d-a843-95523fed1e81","conference_title":"FOSS4G 2019","conference_url":"https://api.media.ccc.de/public/conferences/foss4g2019","related":[{"event_id":7471,"event_guid":"3c2d5b68-ca8e-5c4e-9110-59ad868cfc70","weight":1},{"event_id":7488,"event_guid":"0a3e23aa-d593-58cd-a3a1-7991e3a3a064","weight":2},{"event_id":7516,"event_guid":"edcad3ee-627e-5a69-8432-c12c4a09173c","weight":2},{"event_id":7526,"event_guid":"fd5614a8-535f-5069-8f69-3a9983d37830","weight":1},{"event_id":7528,"event_guid":"92975aff-039a-5545-ba1f-1252a7690110","weight":3},{"event_id":7535,"event_guid":"6f455f9f-a9a4-502e-8e73-b0208dbe8427","weight":1},{"event_id":7536,"event_guid":"9f921eab-53c5-5ce7-9489-45a586162248","weight":1},{"event_id":7543,"event_guid":"7b40d7a8-7350-54ce-9809-87c5b0ee912f","weight":2},{"event_id":7552,"event_guid":"4c2f4b81-1316-502d-870c-dc39567b782e","weight":1},{"event_id":7563,"event_guid":"eac1e444-e3c2-52b6-aea9-c14f53a6ae4b","weight":1},{"event_id":7573,"event_guid":"347ab764-8ae3-58fe-87a0-18dca9880c63","weight":1},{"event_id":7578,"event_guid":"d5d6bac8-cb8a-504a-9a3f-ced5c377e1bd","weight":1},{"event_id":7595,"event_guid":"1b45aaaa-70dc-5f27-8b7b-64dc0fe409a5","weight":1},{"event_id":7599,"event_guid":"6dcfbcee-a817-50dc-a293-f200b4a15b71","weight":2},{"event_id":7604,"event_guid":"b0001b70-6e5d-50e1-aaa4-51345e1d7a65","weight":1},{"event_id":7606,"event_guid":"c0ebaf1b-03d8-53f4-81d1-b5b306e93c60","weight":1},{"event_id":7626,"event_guid":"227ae37a-41aa-53d7-944a-2e9b7c8d99a7","weight":1},{"event_id":7643,"event_guid":"63e1996e-b296-55cb-9fd6-4e4d22e878f6","weight":2},{"event_id":7646,"event_guid":"1e986309-98ba-5840-b70e-300ff54d78bc","weight":1},{"event_id":7663,"event_guid":"1b265f5f-a622-52e0-a2a4-88105aa09aba","weight":1},{"event_id":7664,"event_guid":"bc480eaa-8db8-54d0-bc53-32a81725f2d9","weight":1},{"event_id":7677,"event_guid":"9ba1e879-6d50-5e4b-b3a1-5267a000b2ed","weight":1},{"event_id":7682,"event_guid":"3da56fe5-5d22-565b-849f-591265220120","weight":1},{"event_id":7698,"event_guid":"61a1baea-9b7c-5f64-bef2-094b291f77fd","weight":1},{"event_id":7723,"event_guid":"8ef7bba2-4df3-5bf0-9208-b8f5badad5eb","weight":1},{"event_id":7724,"event_guid":"583daa21-2358-57db-8ee9-d7e1572e4c8f","weight":3},{"event_id":7726,"event_guid":"5fabfcb3-0d99-553b-a6f8-5a6119513afc","weight":2},{"event_id":7734,"event_guid":"0e88cd88-aa0a-5920-9708-e22fbf97b784","weight":2},{"event_id":7738,"event_guid":"ecbd87e4-3c54-5fbe-b5fd-aefc02e7c95d","weight":2},{"event_id":7743,"event_guid":"c393e563-c11d-5111-aa92-fc579ac7ecc9","weight":2},{"event_id":7751,"event_guid":"bb1806af-1579-5ee7-916e-099ef1bb74f1","weight":2}]},{"guid":"3a4e2ca2-c4f2-5516-8f69-01be68113f22","title":"e-shape and PARSEC: Copernicus enabled business opportunities","subtitle":null,"slug":"bucharest-456-e-shape-and-parsec-copernicus-enabled-business-opportunities","link":"https://talks.2019.foss4g.org/bucharest/talk/WLWCE8/","description":"The Copernicus data provided on a free, full and open access basis are an invaluable asset for both established and new businesses.
