The Free and Open source Software Developers' European Meeting (FOSDEM) is a general Open Source conference - one of the largest in Europe. OSM was represented by a stand at most of the last years.


FOSDEM 2017 is a free and non-commercial event bringing together about 5000 developers in Brussels, Belgium, with the goal to provide open source software developers and communities a place to meet and share thoughts. The participation is free of charge, although donations are welcome. The next edition will take place on Saturday 4th and Sunday 5th February 2017, at Université libre de Bruxelles (ULB, Campus du Solbosch, Avenue Franklin D. Roosevelt 50, Brussels 1050, Belgium).

Official site

For the third (!) time there will be a Geospatial devroom and will be happening on Sunday 5/2/2017! Geospatial technologies and mapping used to be specialist work, but nowadays location and maps are becoming part of many projects/applications, which usually use only a small subset of the possibilities the data and software offer. The geospatial devroom is the place to talk about open, geo-related data and software and their ecosystem. This includes standards and tools, e.g. for spatial databases, and online mapping, geospatial services, used for collecting, storing, delivering, analysing, and visualizing purposes.

We welcome submissions about:

  • Web and desktop GIS applications;
  • Collaborative editing / versioning of geodata and metadata;
  • Interoperable geospatial web services and specifications;
  • Collection of data using sensors / UAVs / satellites;
  • Geo-analytic algorithms / libraries;
  • Geospatial extensions for classical databases (indexes, operations) and dedicated databases;
  • Big geodata, scalable GIS applications;
  • Volunteered Geographic information - Crowdsourced geodata.
How to submit a proposal for a talk

Are you thrilled to present your work to other open source developers? Would you like to run a discussion? Any other ideas? Please submit your proposal at:

Make sure to select the 'Geospatial devroom' as 'Track'. If you have an account from previous years, you should be using the same.

Please specify in the notes if you prefer for your presentation either a short timeslot (lightning talks ~10 minutes) or a long timeslot (20 minutes presentation + discussion). However, note that time slots are indicative and will be assigned according to the timing of the session.

The DEADLINE for submissions is Thursday **1st December 2016**.

Notification of acceptance will be sent to the Authors by 11/12/2016 at the latest.

Should you have any questions, please do not hesitate to get in touch with the organisers of the devroom at fosdem-geospatial (at)!
