The geo crate provides geospatial primitive types such as Point, LineString, and Polygon, and provides algorithms and operations such as:
- Area and centroid calculation
- Simplification and convex hull operations
- Euclidean and Haversine distance measurement
- Intersection checks
- Affine transforms such as rotation and translation
- All DE-9IM spatial predicates such as contains, crosses, and touches.
Please refer to the documentation for a complete list.
The primitive types also provide the basis for other functionality in the Geo ecosystem, including:
- Coordinate transformation and projection
- Serialization to and from GeoJSON and WKT
- Geocoding
- Working with GPS data
