OxiGDAL 0.1.6 eliminates rusqlite/libsqlite3-sys and ring from the workspace — SQLite now runs on oxisql-sqlite-compat (Limbo) and TLS on OxiTLS, making the default build 100% C/FFI-free. Plus GPX/KML/TopoJSON formats, non-UTF-8 DBF encoding, Delaunay triangulation, HDF5 v2/v3 superblocks, terrain GLCM/geomorphons/cost-distance, batch QC validators, and W-TinyLFU caching. 78 crates, 18 drivers, 14,605 tests.
OxiGDAL 0.1.5 is a focused fix release: a stray padding field in the RayMarchUniforms WGSL layout was shifting every field by 4 bytes, making the GPU compute kernel read a billion-step max and hang indefinitely on macOS Metal. With the layout corrected, the ray-march GPU/CPU parity test passes in 0.127s. 78 Pure Rust workspace crates, 14,605 passing tests.
OxiGDAL 0.1.4 lands Weiler-Atherton polygon clipping, Karney geodesic area, DE-9IM topology predicates, and marching-squares contours, plus AVX2/NEON SIMD resampling, a completed COPC point-cloud reader, R-tree STR bulk loading + kNN, and a migration from ort to oxionnx for fully Pure Rust ONNX inference. 76 crates, 12,064 passing tests.
OxiGDAL 0.1.2 adds a PMTiles v3 writer with Hilbert tile IDs and content dedup, a full geometry validation/operations module (centroid, area, point-in-polygon, simplify, convex hull), and a unified umbrella crate with 12-format conversion planning. Now 76 Pure Rust workspace crates, 15 format drivers, 10,935 passing tests — zero C dependencies in default features.
Production-grade pure Rust geospatial data abstraction library. 11 format drivers (GeoTIFF/COG, GeoParquet, Zarr, NetCDF, etc.), 211+ EPSG definitions, cloud-native async I/O (S3/GCS/Azure), GPU acceleration (wgpu), WASM + Python bindings. ~480k SLoC, 69 crates, 7,486 passing tests. 10× faster than GeoPandas, <50 MB Docker, no C deps. The sovereign geospatial layer for SciRS2 and the entire COOLJAPAN ecosystem.
The first public release of OxiGDAL: a 100% Pure Rust reimplementation of GDAL with zero C/C++/Fortran in default features. 11 format drivers (GeoTIFF/COG, GeoParquet, Zarr, NetCDF, HDF5, GRIB, JPEG2000, ...), a Pure Rust PROJ with 211+ EPSG definitions, SIMD raster/vector algorithms, cloud-native async I/O, and WASM + Python bindings — across 68 workspace crates.
