This is an experimental fork of OpenLayers 3.1.1 to render digital elevation models using the integrated webgl functionality. The application is not running stable yet and serves only testing purposes.
For comments or contribution please contact Cartography and Geovisualization Group, Oregon State University.
Features at current stage:
- Plan Oblique Relief
- Hypsometric Tinting
- Waterbody Detection
- Hillshading
Run the example with (a sample tileset will be added soon):
./build.py serve
http://localhost:3000/examples/ol3dem.html
The input data has to be encoded and converted into a set of tiles before it can be read by ol3. Regular raster dems such as GeoTiff can be used. For data preprocessing we used dem2tiles. For the actual tile production a modified version of tiler-tools was used.
A working demo is currently available for the eu-dem (Digital Elevation Model of the European Environment Agency).
