Had a great week spending time IRL with my @developmentseed.org team in Lisbon. I work with the smartest, kindest people and I’m feeling energized to finish the year strong and looking forward to 2026. 🫶

Bom dia! 📍DevSeed Lisbon

We’re heading to Auckland 🇳🇿 for @foss4g2025.bsky.social to talk Rust 🦀 + open geospatial. Catch our team showing how modern tools make geospatial faster and more interoperable. Find us for zines + join the GeoRust sprint. Get the deets: developmentseed.org/blog/2025-10... #foss4g #osgeo

Slides for my @foss4gna.bsky.social NA talk, "Cloud-Native Geospatial Metadata with stac-geoparquet" are at www.gadom.ski/presentation... I subtitled the talk "Practical STAC", because #stac-geoparquet was motivated by real-world problems found while managing large @stacspec.bsky.social systems

We took Canada’s Spatial Access Measures dataset (big, clunky CSVs) → turned it into a single GeoParquet file. Add DuckDB-WASM + deck.gl & you get - instant queries - smooth maps - no backend Public data, but actually usable. developmentseed.org/blog/2025-10... @saadiqmohiuddin.bsky.social

New blog post! kylebarron.dev/blog/fast-py... This dives into performance pitfalls of Python bindings, why projects like Lonboard are so fast, and why I care about Apache Arrow so much. The post is high level and you don't need to know C/C++/Rust to understand it!

I'm happy to announce I've been promoted to an Apache Arrow Committer, meaning I'm authorized to merge code patches into Arrow repositories! I join this list of amazing people: arrow.apache.org/committers/

Released Lonboard v0.13! - New layer types: H3, S2, Geohash, A5 and fixed HeatmapLayer - Render data layers beneath Maplibre text labels - Map UI controls: scale, fullscreen, navigation - Significant performance improvements: fixing earlier regressions developmentseed.org/lonboard/lat...

latest out from our lab- led by Saurabh Kaushik- we find at least one geofoundational model (just testing Privthi here) is outperforming CNNs and transformers for mapping glaciers (esp. termini and snouts). we released a dataset with >1800 global images with it too! doi.org/10.1016/j.sr...

Say hi at #FOSS4GNA and grab a zine from our table!
