GEOS Developers

This forum is an archive for the mailing list geos-devel@lists.osgeo.org (more options) Messages posted here will be sent to this mailing list.
This is the developers mailing list for GEOS.

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().
