Three-dimensional mapping products in the form of DEMs (Digital Elevation Models) have become much more accessible in recent years, in part due to the implementation of LIDAR and IFSAR technologies. While there is considerable familiarity with one technology or the other, they are not often examined in terms of their mutually similar characteristics or equally those that are dissimilar. The pur...

We present a system for modeling buildings from a single correlation-based Digital Elevation Model (DEM). The model is constructed in two stages. The first stage segments the DEM into planar surface patches that describe the building. The second stage generates the final polygonal model of the building using weak geometric constraints. We use robust estimation methods at different stages of our...

Heutige Forschungsprojekte im e-Learning-Umfeld vernachlässigen zu oft den Bezug zum Datenschutz und werfen damit Fragen des ethischen Forschens auf. Das vorliegende Papier analysiert Datenschutzfragen bei der Etablierung eines sozio-technischen Systems im Umfeld kleiner und mittlerer Unternehmen (KMU). Wir beziehen uns auf das Beispiel eines noch prototypischen e-Learning-Systems. Dieses liefe...
