The JTS Topology Suite (JTS) is an open source Java software library that
provides an object model for planar geometry together with a set of
fundamental geometric functions. JTS conforms to the Simple Features
Specification for SQL published by the Open GIS Consortium. JTS is
designed to be used as a core component of vector-based geomatics software
such as geographical information systems. It can also be used as a
general-purpose library providing algorithms in computational geometry.
JTS is open source software. It is dual-licensed under:
