We visualize Denmark’s Digital Elevation Model in real-time, directly in a browser using WebGL. A virtual texturing technique is applied which enables us to handle a virtual raster size of 1048576 x 1048576 pixels. Hence, it is possible to cover the whole country, except Bornholm, with 40 cm horizontal resolution.
