GeOxygene 1.3

GeOxygene project provides a development framework for GIS applications which implements OGC/ISO spec.

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 Geographique 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.

JData 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.

Requirements:

· Java

What's New in This Release:

· Adding a data matching tool.
· Adding a simple method to create minimal spanning trees.
· Adding a generator of DBMS tables and XML mapping files from Java classes.
· Improvment of the GeOxygeneReader methods to partially take into account the GM_Aggregate geometry type (useful to visualize data matching results).
