Developed a geocoding and spatial analytics extension for the duckdb/community-extensions repository, enhancing DuckDB’s geospatial analysis capabilities. The extension introduced geocoding, category normalization, and spatial tiling features, leveraging Overture Maps data to support advanced location-based analytics. Built primarily in C++ with SQL integration, the work included implementing Overture Maps helpers and ensuring seamless compatibility with DuckDB’s extension framework. This addition enabled developers and analytics teams to perform more sophisticated spatial queries and integrate geospatial workflows directly within DuckDB. The project focused on robust database development and geospatial analysis, opening new possibilities for downstream business analytics in the DuckDB ecosystem.
