Here is the canonical example of building an approximately circular patch byīuffering a point, using the scalar Geometry interface: > from shapely import Point > patch = Point ( 0.0, 0.0 ). Internally release this constraint so that the heavy lifting done by GEOS canīe done in parallel, from a single Python process. Multiple threads from computing at the same time. Shapely functions generally support multithreading by releasing the Global The underlying for loops are implemented in C to reduce the N-dimensional arrays on an element-by-element fashion and supports arrayīroadcasting. What is a ufunc?Ī universal function (or ufunc for short) is a function that operates on Systems, but can be readily integrated with packages that are. Shapely is not primarily focused on data serialization formats or coordinate NumPy ufuncs for operations using arrays of geometries. Geometry interface for singular (scalar) geometries and higher-performance

Shapely wraps GEOS geometries and operations to provide both a feature rich Geometry library GEOS (the engine of PostGIS, and a port of JTS). It is using the widely deployed open-source Shapely is a BSD-licensed Python package for manipulation and analysis of Manipulation and analysis of geometric objects in the Cartesian plane.
