duckdb_spatial | geospatial extension for DuckDB that adds support

duckdb_spatial is a C library. duckdb_spatial has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

This is a prototype of a geospatial extension for DuckDB that adds support for working with spatial data and functions in the form of a GEOMETRY type based on the the "Simple Features" geometry model, as well as non-standard specialized columnar DuckDB native geometry types that provide better compression and faster execution in exchange for flexibility. Please note that this extension is still in a very early stage of development, and the internal storage format for the geometry types may change indiscriminately between commits. We are actively working on it, and we welcome both contributions and feedback. Please see the function table or the roadmap entries for the current implementation status. If you or your organization have any interest in sponsoring development of this extension, or have any particular use cases you'd like to see prioritized or supported, please consider sponsoring the DuckDB foundation or contacting DuckDB Labs for commercial support.
