Features:
- Read/write various GIS vector formats (Shapefile, GeoJSON, GeoPackage, KML, etc.), simple feature model (GeoJSON-like), access to feature geometries and attributes, coordinate reference system (CRS) handling, integration with other Python GIS packages (e.g., Shapely, GeoPandas), command-line interface (fio).
Pricing:
- Free
- Pythonic and easy-to-use API for GIS vector data I/O, depends on the robust GDAL/OGR library, good for automating geospatial workflows, handles real-world data complexities, supports many formats.
- Installation can be complex due to GDAL dependency, especially if specific format drivers are needed beyond the defaults in binary wheels; primarily focused on simple features vector data, not raster data or complex topological operations.
Best for:
- GIS analysts, geographers, and developers working with geospatial vector data for reading, writing, analysis, manipulation, and conversion tasks in Python.
