GEOS is a complete C++ implementation of the functions and predicates defined in the OpenGIS "Simple Features for SQL" specification.

GEOS library 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.

IMPORTANT: GEOS 2.0.0 is not compatible with PostGIS 0.8 or lower. Do not upgrade to GEOS 2.0.0 unless you also upgrade your version of PostGIS at the same time to PostGIS 0.9 or greater.

What's New in This Release:

Performance was improved in OverlayOp::insertUniqueEdge(), which improves intersection, union, and buffer.

Memory management and allocation/deallocation were improved.

Higher dimension support was implemented for some operations.

WKB input/output was added.

A new stable C API was added.
