JTS Topology Suite

About

JTS Topology Suite is a Java library of 2D spatial predicates and functions implementing the OGC Simple Features for SQL specification. It provides a robust, high-performance geometry model and operations used by GeoTools, GeoServer, and many other Java GIS projects. Its design has been ported to C++ as GEOS and to JavaScript as JSTS, making it the reference implementation lineage for much of open-source geometry processing.

Features

• OGC Simple Features geometry model
• Robust 2D spatial predicates and operations
• Basis for GEOS, JSTS, and NetTopologySuite
• WKT, WKB, and GML input/output
• Used by GeoTools and GeoServer
