It aims to contain the complete functionality of JTS in C++. This includes all the ​ OpenGIS Simple Features for SQL spatial predicate functions and spatial operators, as well as specific JTS enhanced functions. provides spatial functionality to many other projects and products . is a project of ​ OSGeo .

A "New Ticket" button will appear once you have logged in . When submitting bugs caused by particular geometries ( TopologyExceptions , for example), you must submit the geometries that cause the failure, preferably in hex-encoded WKB , so that we can re-produce the failure cases.
