JTS Topology Suite
open-in-new
<p>JTS Topology Suite (Java Topology Suite) is an <a href="/facts/Open-source_software/HzTaB8E9">open-source</a> <a href="/facts/Java_(programming_language)/9ScgFyAL">Java</a> <a href="/facts/Software_library/xRzL3P7q">software library</a> that provides an object model for <a href="/facts/Euclidean_geometry/V6cTcoCy">Euclidean</a> planar linear <a href="/facts/Geometry/wTQf5ffQ">geometry</a> together with a set of fundamental geometric functions. JTS is primarily intended to be used as a core component of <a href="/facts/GIS/PoP1kVoa">vector-based</a> <a href="/facts/Geomatics/Ig6LVnpJ">geomatics</a> software such as <a href="/facts/Geographical_information_system/PoP1kVoa">geographical information systems</a>. It can also be used as a general-purpose library providing <a href="/facts/Algorithm/fnl5NmRt">algorithms</a> in <a href="/facts/Computational_geometry/eeaotQtl">computational geometry</a>. </p><p>JTS implements the geometry model and API defined in the <a href="/facts/OpenGIS/uDKbX6Cl">OpenGIS</a> Consortium <a href="/facts/Simple_feature_access/R8bwfcrs">Simple Features Specification for SQL</a>. JTS defines a standards-compliant geometry system for building spatial applications; examples include viewers, spatial query processors, and tools for performing data validation, cleaning and integration. </p><p>In addition to the Java library, the foundations of JTS and selected functions are maintained in a C++ port, for use in C-style linking on all major operating systems, in the form of the GEOS software library. </p><p>Up to JTS 1.14, and the GEOS port, are published under the <a href="/facts/GNU_Lesser_General_Public_License/AXwkz9x3">GNU Lesser General Public License</a> (LGPL). </p><p>With the LocationTech adoption future releases will be under the EPL/BSD licenses. </p>
