GEOS (Geometry Engine - Open Source) is a C++ port of the Java Topology
Suite (JTS). As such, it aims to contain the complete functionality
of JTS in C++. This includes all the OpenGIS "Simple Features for SQL"
spatial predicate functions and spatial operators, as well as specific
JTS enhanced topology functions.
