Introduction

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. It is released under the terms of the LGPL (GNU Lesser General Public License) license.

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.

Data are stored in a relational DBMS (RDBMS) to ensure a rapid and reliable access to the system but users do not have to worry about any SQL statements: they model their applications in UML and code in Java. Mapping between object and relational environments is performed with open source software. At present, OJB is supported and the mapping files for the storage of geographic information in Oracle or PostGIS are provided to users.

News

• 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
