GEOS - Geometry Engine, Open Source

GEOS (Geometry Engine - Open Source) is a C++ port of the Java Topology Suite (JTS). As such, 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 topology functions.

GEOS is available under the terms of GNU Lesser General Public License (LGPL).

Bug Reporting

You will need an OSGeo user account to submit bugs here. 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.

Governance

The GEOS project is run by a Project Steering Committee made up of developers and contributors to the project. Major project decisions are made via a Request for Comments process, where proposals are first documented and then voted on by the steering committee.
