3D city models represent urban situations in spatial views. By this method can be avoided loss of information through technical drawings, where the laity is not always the clearest information provided.
Extraction of surfaces from laser scan data provides a wealth of potential applications. As part of the Christian Doppler Laboratory for over 6 years we have been developing in collaboration with the Technical University of Vienna IPF methods for automatic building extraction from laser data.
The data obtained is not only for city models but as used for solar potential analysis.
