3D city models have a wide range of applications such as mobile navigation, urban planning, telecommunication, and tourism. The generation of high resolution Digital Surface Models (DSMs), in particular from airborne LIDAR data have found a major attraction of researchers in this field due to their high accuracy and high density of points. In this paper, a new approach is proposed for the generation of 3D models of buildings that are extracted from a high resolution DSM. Particularly the complex buildings containing several smaller building parts are discussed. The building parts are individually modeled by a projection-based method and merged to form the final 3D model. The following building parts are considered to be modeled in the proposed approach: (1) flat roof, (2) gable roof, (3) hipped roof, and (4) mansard-shaped roof buildings. The complex buildings are decomposed into several parts according to the number of existing ridge lines.
