Urban Perspectives: A Raster-Based Approach to 3D Generalization of Groups of Buildings
The suggested method for 3D generalization of groups of buildings is based on rasterization of 2D footprints of the 3D buildings. The rasterization is processed within quarters, which are automatically defined by using Digital Elevation Model (DEM), water objects and roads. The 3D urban perspective is computed based on separate levels of generalization of each quarter as a function of its distance from a pre-defined view point.
