Description

In the context of the bundle project undefined Abstraction of Geographic Information within the Multi-Scale Acquisition, Administration, Analysis and Visualization funded by the German Research Foundation (DFG) we work on the subproject Ontological Scales for automated detection, efficient processing and fast visualization of landscape models together with our project Partners at Universität Bonn at the Institutes of undefined Photogrammetry and Geoinformation.

Tasks in Computer Graphics

sensor fusion
model-based reconstruction
parameterized prototypes
efficient LOD structure
hybrid rendering (points/triangles/polyhedra)
semantic-based navigation
semantic-based interaction
