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.

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.

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!

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...

DevSeed intern Beatriz Peres used ESA’s new Sentinel-1 Zarr to analyze the 2024 Valencia floods with lightweight, time-series workflows.

We built stac-map, a lightweight, map-first prototype for exploring STAC GeoParquet in your browser. Built w/ DuckDB, geoarrow, & semantic STAC search, explore STAC GeoParquet files directly in the browser.

Try it: developmentseed.org/stac-map/

Blog post up for stac-map: developmentseed.org/blog/2025-09...

A very imperfect prototype of a map-first #STAC app, it includes:

- stac-geoparquet visualization and download
- Experimental natural language collection search

Uses #deck.gl, @duckdb.org, #geoarrow, and github.com/stac-utils/r...
