3D building reconstruction is a challenging problem addressed
by many researchers. Since airborne LIDAR data appeared as a
new data source in remote sensing and photogrammetry many attempts
were made to model buildings using LIDAR data. LIDAR
combined with aerial images was e.g., used for building reconstruction
by (Haala and Anders, 1997, Rotensteiner and Jansa,
2002).
