Kristin Cowalcijk

Developed foundational GDAL integration for the apache/sedona-db repository, establishing a robust wrapper layer in Rust to support both raster and vector geospatial operations. The work included designing standalone geometry, geotransform, and spatial reference wrappers, as well as safe abstractions for datasets, drivers, raster bands, features, and layers. By wiring core raster and vector modules, the implementation enabled higher-level geospatial data processing while clarifying module boundaries for future maintainability. Additionally, improved test stability for GDAL 3.10 and above by ensuring proper GPKG metadata handling and resource cleanup, addressing potential memory leaks and enhancing reliability in backend geospatial workflows.
