GeOxygene aims at providing an open framework which implements OGC / ISO specifications for the development and deployment of geographic (GIS) applications. It is a open source contribution of the COGIT laboratory at the IGN (Institut Géographique National), the French National Mapping Agency.

GeOxygene is based on Java and open source technologies and provides users with an extensible object data model (geographic features, geometry, topology and metadata) which implements OGC specifications and ISO standards in the geographic information domain. The support of the Java interfaces developped by the open source GeoAPI project is planned.

GeOxygene is an open source project made available to you using an open source license described here.


  • January, 2014 - Version 1.6 released

    This new version includes the EstIM model developed during the Jean-François Girres PhD (2012), a new OSM module, new tools for managing style (editor, import and export SLD). The old GeOxygene 2D graphical interface and CartaGen graphical interface merge.

  • June 10, 2013 - What’s New in GeOxygene 1.5

    The presentation on GeOxygene 1.5 at FROG 2013 in Saint-Mandé will focus on the new features, including a description of the three new modules : geoxygene-semio (semiology), geoxygene-sig3d (3D) and geoxygene-cartagen (generalization).

  • January, 2013 - Version 1.5 released

    This new version includes :

    • a new semiology module with a model of legend detailed here.
    • a new 3D module provides a dedicated GUI mapping tool that is optimized to manipulate 3D geometry, to import special format like CityGML, postgis 3D, ..., to use objects and algorithms dedicated to 3D
    • a new generalization module provides generalization algorithms, spatial analysis api (Multi-criteria decision analysis, ...), methods for calculating compactness, curves, congestion
    • data matching process using theory of Evidence

    Technically, the project has adopted a new multi-module Maven architecture.

  • June 22, 2009 - Version 1.4 released

    This version provides an ISO1909 General Feature Model implementation, a SLD (Styled Layer Descriptor) implementation based on the OGC 02-070 implementation specification, an Hibernate support, a first version of the new GeOxygene interface, some code examples to learn how to use the topoligical map and the data matching tool, and a complete Java 6 support in regard to Java 6 specifications (types, annotations, etc.).

  • January 31, 2008 - Version 1.3 released

    This version provides a data matching tool.

  • August 8, 2007 - Version 1.2 released

    This version provides new tools (topological map, geometric tools, Delaunay’s triangulation) and corrects some minor bugs.

  • September 12-15, 2006 - GeOxygene will be at FOSS4G

    A technical workshop on GeOxygene is organised during the 4th edition of the Free and Open Source Software for Geoinformatics conference, FOSS4G 2006, Lausanne, Switzerland, September 12-15, 2006.

  • June 12, 2006 - Version 1.1 released

    This version corrects some minor bugs and enhances the support of PostGIS.

  • May 8, 2005 - GeOxygene 1.0 released

    After two years of development, testing and debug, version 1.0 of GeOxygene is released.
