Mesh simplification for building typification

This paper describes a deterministic approach for the typification of buildings which uses several levels of details for the derivation of intermediate scales. The typification procedure is modeled as a two-tier process, with the steps positioning and representation. While the first step determines the number and the position of the building objects with respect to the requested scale, the representation step is used to calculate size and orientation for the replacement buildings. The positioning is performed using a mesh optimization technique adapted from the area of computer graphics. The approach was originally developed for surface reconstruction and mesh simplification. With help of one additonal parameter the building density could be controlled, e.g. it is possible to emphasize areas with high building density.
