This package is based on the package 'libgeos' from project 'Application:Geo'.

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 topology
functions such as IsValid().
