= GEOS - Geometry Engine, Open Source =

GEOS (Geometry Engine - Open Source) is a C++ port of the [http://sourceforge.net/projects/jts-topo-suite/ 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.

=== Bug Reporting ===

You will need an [http://www.osgeo.org/osgeo_userid/ OSGeo user account] to submit bugs here. A "New Ticket" button will appear once you have [http://trac.osgeo.org/geos/login logged in].

When [http://trac.osgeo.org/geos/newticket submitting bugs] caused by particular geometries (TopologyExceptions, for example), you must submit the geometries that cause the failure, preferably in [HexEncodedWkb hex-encoded WKB], so that we can re-produce the failure cases.
