JTS
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 OGC|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 JavaTM
- JTS is open source (under the LGPL license)
Für topologische Funktionen wird die DE-9IM Matrix verwendet.
