# JTS Topology Suite

Canonical: https://gisforweb.com/tools/jts/

Java library of 2D spatial predicates and functions; the design behind GEOS and JSTS.

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.
