摘要：This paper aims at multiscale representation of urban GIS, presenting a model to dynamically generalize the building on the basis of Delaunay triangulation model. Considering the constraints of position accuracy, statistical area balance and orthogonal characteristics in building cluster generalization, this paper gives a progressive algorithm of building cluster aggregation, including conflict detection (where), object (who) displacement, and geometrical combination operation (how). The algorithm has been realized in an interactive generalization system and some experiment illustrations are provided.
