OpenStreetMap 3D - a Web 3D Service (W3DS) based on user-generated free geodata

Open Source data i 3D ...

Open Source data goes 3D ...


A first prototype is available for entire Germany  - Integration of OpenStreetMap and Digital Elevation Models and their use by means of interoperable GI-Web Services-http://www.osm-3d.org/ 

In the context of the research project 'Geodata Infrastructure 3D' the open geodata of OpenStreetMap (OSM) and the elevation data of the Shuttle Radar Topography Mission (SRTM) were used for the development of a 3D Geodata Infrastructure (GDI-3D) based on open web service standards of the Open Geospatial Consortium (OGC). 
Entire Germany was used for a first test case.
A Web 3D Service (OGC W3DS) is providing the data as a 3D scene graph to the client. The first prototypical visualization of the OpenStreetMap data in 3D takes place in a W3DS client (XNavigator). In contrast to server side rendered maps (as in typical Web Map Services like www.osm-wms.de) a completely free client side interaction and navigation is possible. As all data is passed to the client computer a good internet connection and recent computer with its own graphic card are needed (cmp. system requirements). Therefore this method is also especially suitable for intranets. [...]
