GEOS is a complete C++ implementation of the functions and predicates
defined in the OpenGIS "Simple Features for SQL" specification. It includes
high quality implementations of all the important spatial relationships and
operations, robust versions of all functions in the dimensionally extended
9 intersection predicate model, implementations of the operators, Buffer(),
Union(), and Intersection(), and all other SFSQL functions including Area(),
Length(), Centroid(), etc.
