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
... [More] algorithms
* JTS is fast enough for production use
* JTS is written in 100% pure Java(
* JTS is open source (under the LGPL license) [Less]
