The demo version of a potential 3D Viewer for geo.admin.ch - the geo-portal of the Swiss Confederation - is online at http://swiss3d.openwebglobe.org until July 31, 2012.
The 3D Viewer is based on the open source globe “OpenWebGlobe” using WebGL.
The scene convers entire Switzerland and is based on high resolution data from swisstopo: SWISSIMAGE, DHM25 and swissBOUNDARIES3D as well as extracts from swissBUILDINGS3D.
In addition, textured 3D objects from FHNW Muttenz and EPFL Lausanne are available. Outside the area with high-resolution data, Blue Marble from “NASA’s Earth Observatory” is used.
The total amount of texture and geometry data exceeds 2 TB and is being handled using the cloud from Amazon Web Services.
This demo has been developed by FHNW - University of Applied Sciences and Arts Northwestern Switzerland, camptocamp SA, the Federal Office of Topography, Switzerland, and geo.admin.ch.
