A MWVD-based Algorithm for Point Cluster Generalization

A new algorithm based on a multiplicative weighted Voronoi diagram(MWVD) was proposed in this paper.The idea of the algorithm is to: select appropriate factors for describing the statistical,thematic,topological and metric information,and integrate the factors in the process of point feature generalization to ensure different types of information may be transmitted correctly,and the generalization of point clusters is done by repetitively constructing MWVDs.
