Shapely

Shapely is a BSD-licensed Python package for manipulation and analysis of planar geometric objects. It wraps the widely deployed open-source geometry library GEOS (the engine of PostGIS) to provide both a feature-rich Geometry interface for scalar geometries and high-performance NumPy ufuncs for operations on arrays of geometries. The current version is 2.1.2, with a regular release cadence that includes bug fixes, new features, and compatibility updates for Python and GEOS versions.
