geofileops

Geofileops is a Python toolbox designed to significantly speed up the processing of large geospatial vector files. It provides a robust set of functionalities for common GIS operations, making it an invaluable resource for developers and data scientists working with extensive geographic datasets.

The toolbox supports a wide array of typical GIS operations, including union, intersect, buffer, dissolve, and clip. While tested on both GeoPackage and Shapefile input files, GeoPackage is recommended for optimal performance. The tool is also compatible with other file formats supported by GDAL/OGR, offering broad applicability for various geospatial data types.

To achieve its impressive speed, geofileops employs several advanced techniques. It processes data in batches, intelligently subdivides and merges complex geometries on the fly, and utilizes different passes for data handling. Crucially, it is designed to leverage all available CPU cores, enabling parallel processing and substantial performance gains, especially when dealing with very large datasets that typically involve hundreds of thousands of polygons.
