FOSS4G (Events)

The internationally acclaimed “Free and Open Source Software for Geospatial” conference is our annual global conference held in a different city each year since 2004. It regularly attracts over 1,000 practitioners and advocates for Free and Open Source Software for Geospatial.


With a robust schedule of keynote speakers, workshops, paper sessions and talks, FOSS4G offers a great opportunity for newcomers and regular visitors alike. This ‘annual gathering of the tribes’ boasts:

  • A massive selection of presentations
  • A variety of workshops for hands on training
  • A continuous opportunity for networking
  • Combined with a mix of social events, because open source is fun!

If you cannot make it to our global conference many regions and countries host smaller FOSS4G events, reach out to your local chapter to learn more.
