Check out the the README on Github for how to use the project for your own project!
This project is based off of one I did for the 2025 FOSS4GNA conference, however that one was heavily pushed through AI due to the short time to finish it. I came away from that glad I did it, but not feeling like I learned much or understood any of it. This year I did the majority of the refactoring by hand, using Claude mainly for some data cleaning where the topics were in a column separated by commas, but one of the topics also had a comma in it. It was able to fix that much faster than I could by manually cleaning or thinking up a way to do it with code. I also used it to check some of the javascript filter logic I changed, because I know just enough javascript to read it and kind of understand it, but not an expert in it by any means.
Filters
Pyvis has built in filtering available, but I didn’t like how it looked or worked, so I reused the code generated by Claude for that from last year and reconfigured it to work with the different organization we used this year where tracks options are Application, Technical, Community of Practice, or Business of Open Source, and Topics replaced the dual Track/Tag setup I used in the 2025. This has the benefit of not having to duplicate nodes for the same Track and matching Tag.

Date
The conference runs November 2-4. The workshops are all on November 2nd, and the 3rd and 4th are all talks or other events. Use this filter to filter by day.
Types
There are a range of different activities at the conference. The majority includes the 25-30 minute talks on the 3rd and 4th, however there are 12 pre-conference 3 hour workshops on the 2nd that require additional registration, plus a number of other free workshops available as Conference Events. The Keynote speeches are a chance for everyone to gather and learn from the leaders shaping open source geospatial. There are also posters available for viewing, and this year we’ve introduced 5 minute Lightning Talks for those ideas that aren’t quite ready for a full talk slot.
Tracks
Tracks include Application, Technical, Community of Practice, or Business of Open SourceApplication
This track is for presentations centered on what was built and why it mattered — real deployments, workflows, or projects that used open source geospatial tools to solve a concrete problem. The emphasis is on the problem, the context, and the results rather than the technical internals. Strong fits include a podium talk on using QGIS and OpenStreetMap to support disaster response logistics, a workshop on building a public-facing flood risk map with open data, a lightning talk on a city’s switch from proprietary GIS to an open stack, or a poster showing a conservation land prioritization analysis.
Technical
This track is for presentations that go under the hood — covering how tools work, how systems are built, or how specific methods are implemented. Proposals in this track should lead with code, architecture, algorithms, or technical workflows rather than outcomes or impact. Strong fits include a workshop walking through PostGIS spatial analysis functions, a podium talk on optimizing tile serving with PMTiles, a lightning talk on a new GDAL driver, or a poster comparing the performance of different routing engines.
Business of Open Source
This track is for presentations that grapple with the harder questions of how open source geospatial projects survive and thrive — funding models, organizational governance, vendor relationships, licensing, and the tension between open and commercial. Strong fits include a podium talk on how a nonprofit funds core FOSS4G infrastructure, a lightning talk on dual-licensing trade-offs, a workshop on writing grant proposals for open source projects, or a poster comparing governance models across major geospatial foundations.
Community of Practice
This track is for presentations about how people work together, learn, and grow within the open source geospatial ecosystem. Proposals here focus on people, process, and shared knowledge rather than specific tools or deployments.
Strong fits include a podium talk on building a regional OSM mapping community, a workshop on getting started contributing to an open source project, a lightning talk on lessons learned running a university GIS open lab, or a poster on emerging standards and how practitioners are adopting them.Topics
Each presentor can pick several topics, which describes the subject matter regardless of Track. Topics replace last year’s Track/Tag pairing, and reduce clutter in the graph view.
The topics cover the full stack of open source geospatial work. Some are about the technology itself: Cloud Native Geo, Spatial Databases & Interoperability, Spatio-Temporal Asset Catalog, Discrete Global Grid Systems, Raster and Remote Sensing, and Web Mapping & Geospatial Visualization. Others focus on analysis and emerging methods, such as Geospatial Data Science, Geo AI & Machine Learning, and Emerging Tech & Future Directions.
Several topics are about applying these tools to real-world problems: Disaster Response & Resilience, Environment, Climate & Sustainability, and Infrastructure & Resource Systems. Others address the health of the ecosystem itself: Funding Models, Commercialization Strategies, Open Source Maintenance & Support, Cybersecurity, Open Data, and User Accessibility. Finally, Open Geospatial Tools, Research & Education, Workflows & Reproducibility, and State-of-Software cover how the community learns, shares, and tracks progress. Anything that doesn’t fit is under Other.
