Geometry engine for Geographic Information Systems - C Library
GEOS provides a spatial object model and fundamental geometric functions. It implements the geometry model defined in the OpenGIS Consortium Simple Features Specification for SQL. Functions provided include:
* spatial predicates (based on the DE-9IM model),
* overlay functions (intersection, difference, union,
symmetric difference),
* buffer,
* convex hull,
* area and distance functions, and
* topological validity checking
This package contains the C library. A C++ library is provided by the libgeos-* package.
