JTS Topology Suite (JTS)
================================================================================

The JTS Topology Suite is an open source (LGPL) Java API of spatial predicates and functions for
processing geometry.  JTS offers a complete, consistent, robust implementation of fundamental
algorithms for processing linear geometry on the 2-dimensional Cartesian plane.

JTS is written in 100% pure Java and is fast enough production use.

Computational stability in JTS project is backed by an extensive set of tests. A small application
is provided to run tests tests and experiment with Geometry interactively. We hope to include this
application on future editions of the OSGeo-Live project.

Aplikacje OSGeo-Live bezpośrednio używające JTS:
:doc:`52nSOS_overview`,
:doc:`52nWPS_overview`,
:doc:`kosmo_overview`,
:doc:`52nWSS_overview`,
:doc:`atlasstyler_overview`,
:doc:`geomajas_overview`,
:doc:`saga_overview`,
:doc:`geonetwork_overview`,

:doc:`geoserver_overview`,
:doc:`udig_overview`,
:doc:`geotools_overview`,
:doc:`openjump_overview`,
:doc:`zoo-project_overview`,
:doc:`gvsig_overview`

Aplikacje OSGeo-Live posiadające własne implementacje Geoemtrii, bazujące na operacjach JTS:
:doc:`deegree_overview` (GML3 geometry),
:doc:`geotools_overview` (ISO 19107 Geometry)

Projekt :doc:`geos_overview` jest portem JTS do środowiska C++, który pozwala na
użycie tych wysokiej jakości operacji w wielu innych aplikacjach. Dodatkowe porty są 
dostępne dla C# i JavaScript.
