A topology processing library: Geometry Engine - Open Source
From GEOS homepage:
GEOS (Geometry Engine - Open Source) is a C++ port of the Java Topology Suite (JTS).
It has at least Python bindings: geoDjango.
GEOS has multiple other meanings in computing, starting from a graphical operating system for Commodere C64, but they are less relevant to SO today.
