Call for Talks & Workshops

FOSS4G is the international conference on open source geospatial software, so every submission should revolve around open source software in some way:

  • the open source geospatial software you work on and how it works,
  • how you use open source geospatial software to solve your problems,
  • how open source geospatial software makes your organization better,
  • what you learned from working with open source geospatial software,
  • an important problem you solved with open source geospatial software,
  • your work or your organizations work and how open source geospatial software have effected them
  • and so on.

Have a look at accepted talks for prior years (2019, 2018, 2017), to get a feel for the kind of topics that make up a FOSS4G presentation program.


  • Talks are usually verbal presentations with an audio-visual component in the form of a slide deck or live demonstration. There have been musical and dramatic presentations in the past, but those are rare events.
  • Talk slots are a total of 25 minutes for the talk and Q&A, with 5 minutes between presentations for presenters to set up and the audience to change rooms as desired.
  • A limited number of "XL Talk"" slots (55 minutes) will be offered to speakers with popular topics, as determined by community review and the Program Committee. If you are interested in a longer slot, check the XL Talk option during submission.


  • Workshops are hands-on teaching sessions, 3 hours in length.
  • Workshops are usually organized around teaching a specific FOSS4G software package, through some kind of practical problem solving.
  • Workshops will be held in the conference center, on the day before the start of the presentation programme.
  • Students will be encouraged to bring their own laptops.
  • Teachers should be prepared to provide students with container images, VM images, or login to cloud systems to support quick set-up times and avoid installation snafus.
