JTS Topology Suite

The JTS Topology Suite is an API of 2D spatial predicates and functions. It has the following design goals: * JTS conforms to the Simple Features Specification for SQL published by the Open GIS Consortium * JTS provides a complete, consistent, robust implementation of fundamental 2D spatial algorithms * JTS is fast enough for production use * JTS is written in 100% pure Java(TM) * JTS is open source (under the LGPL license)
