# About deegree
| Copyright by: |
deegree is a free software initiative founded by the GIS and Remote Sensing unit of the Department of Geography, University of Bonn, and lat/lon. We would gladly welcome any contribution to further development and implementation. The Free Software project deegree offers the substantial building blocks for the building of a Spatial Data Infrastructure by implementing the standards of the Open GIS Consortium (OGC) and ISO/TC 211. As the whole architecture of deegree is based on OGC specifications and concepts, there are no problems to integrate standardized products of other vendors (e.g. ArcIMS by ESRI(c)). All of the mentioned server-side services and the client framework are supplied by the Open Source project deegree. deegree is free software, no license cost have to be provided to use it. It can be copied and distributed freely, even an extension of enhancement of the system does not result in license costs. Openness of the source code underlines investment security of the system. As deegree is implemented in Java it is platform-independent and can be utilized in heterogeneous networks. Installations are already running on Windows XP/2000/NT, LINUX, Macintosh OS X and Solaris Servers. deegree is free in the sense that it is protected by the GNU Lesser General Public License.
