The increasing need for describing 3D spatial data in urban areas has led to the development of 3D city models or more widely 3D GIS. Recently, the airborne remote sensing industry has supplied a new way for fast acquisition of 3D spatial data with high densities and increased accuracy at lower cost. At mean time, exiting maps and 2D spatial databases have also supplied a well-organized infrastructure to be used for 3D data extension. In this paper, a integrated method for large scale 3D-city modeling based on multi-viewed laser range images and existing maps is presented, in which we want to integrate different kinds of data from multi-sources, optimizing the different algorithms, and to find a suitable way for operationally generating 3D spatial databases and reducing the related cost and time. Finally, an example is given to demonstrate the operational applicability of the suggested approach.
