JTS Topology Suite

The JTS Topology Suite ( JTS ), formerly Java Topology Suite is a free program written in Java library that provides a spatial object model and fundamental geometric functions.

The suite was developed by Vivid Solutions. The implemented model geometry corresponds to the Simple Feature Access specification of the Open Geospatial Consortium ( OGC). The main types of geometry are point (point ), line ( Line String) and area ( polygon ) and the corresponding multi-variant ( multipoint, multiline string, multi- polygon ).

The API supports custom precision models and contains codes for robust geometric computations and spatial indexes.

JTS is used by a number of other open source projects, such as GeoTools, GeoServer, uDig and OpenJUMP.

A port in C is the Geometry Engine Open Source ( GEOS ).
