Digital elevation models (DEMs) are getting increasingly more detailed. For instance, the entire land surface of Austria is available with a resolution of 1x1 meters (and sometimes even more). This resolution is a number of magnitude higher than DEMs used by commercial 3D map applications, for example Google Earth. We can render these highly detailed models in real-time to let users interactively fly through Austria's mountainscape and inspect the terrain in great detail. This opens up ample opportunities for interesting applications, such as tour planning on a level of detail that has not been possible with lower resolution and therefore highly smoothed elevation models.


In this work, a student should design and implement an effective and aesthetic visualization of hiking routes in such a 3D environment. A special focus will lie on occlusion management, e.g., when parts of a hike are on the backside of a mountain or lead through a dense forest. 

The specific tasks will be scaled to the type of project (BA / PR / DA). 


  • Strong interest in web-based visualization and rendering
  • Very good programming skills
  • Experience with web technologies (JavaScript, WebGL, ...) advantageous


The current prototype is implemented in JavaScript and WebGL. 

Outdoor enthusiasts are very welcome and in good company!
