LocationTech JTS Topology Suite

Primary tabs


The LocationTech JTS Topology Suite is a Java API of spatial predicates and functions for processing vector geometry.

It has the following design goals:

  • JTS conforms to the Simple Features Specification for SQL published by the Open Geospatial Consortium
  • JTS provides a consistent and robust implementation of fundamental algorithms for processing vector geometry
  • JTS is highly performant due to its use of innovative and optimized geometric algorithms/li>
  • JTS is written in 100% pure Java

JTS also includes:

  • The JTS Test Suite, an extensive set of geometric unit tests for OGC SFS and JTS functions
  • The JTS TestBuilder, a GUI tool for creating, editing, viewing and processing geometry
