go-geom

Package geom implements efficient geometry types for geospatial applications.

Key features

• OpenGeo Consortium-style geometries.
• Support for 2D and 3D geometries, measures (time and/or distance), and unlimited extra dimensions.
• Encoding and decoding of common geometry formats (GeoJSON, KML, WKB, and others) including sql.Scanner and driver.Value interface implementations for easy database integration.
• 2D and 3D topology functions.
• Efficient, cache-friendly internal representation.
