Shapely is a BSD-licensed Python package for manipulation and analysis of planar geometric objects. It is based on the widely deployedGEOS(the engine ofPostGIS) andJTS(from which GEOS is ported) libraries. Shapely is not concerned with data formats or coordinate systems, but can be readily integrated with packages that are. For more details, see: •Shapely GitHub repository •Shapely ...

We can now interrogate the collection. Many shapely operations result in a different kind of geometry than the one you're currently working with. Since our geometry is a collection of points, I can instantiate a MultiPoint, and then ask that MultiPoint for its envelope, which is a Polygon. Easily done like so:

Shapely is a Python package for set theoretic analysis and manipulation of planar features using (via Python·s ctypes module) functions from the well known and widely deployed GEOS library. GEOS, a port of the Java Topology Suite (JTS), is the geometry engine of the PostGIS spatial extension for the PostgreSQL RDBMS. The designs of JTS and GEOS are largely guided by the Open Geospatial ...
