libgeos-3.9.0 - 3.9.0-1 main

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 stable C library is provided
by the libgeos-c* package and should be preferred by third-parties
programs.
