We’re chuffed to announce the 0.2 release of the GeoArrow specification! We released the first version in September, 2023 and have since worked with the community towards our vision that getting spatial data from one library to another should be fast, easy, and preserve important spatial properties like the CRS.

Since our first release, GeoArrow has been adopted by GeoPandas, GDAL, Apache Sedona, DuckDB, Lonboard, Kepler, and others. It has never been easier (or faster) to get spatial data from one tool into another!

We’ve also worked hard over the last year to improve our language bindings in Rust, C/C++, R, and Python. Wherever you can find Apache Arrow, there's (probably) a GeoArrow implementation to help!

Finally…we have great test data! This has been essential for testing our bindings and integrations with other libraries but also makes it easy (and far less boring) to generate non-trivial examples when writing about our work.

Special thanks to @kylebarron and @jorisvandenbossche for co-creating and maintaining this specification! We’re all excited to see what this can unlock for the spatial community and beyond 🌏
