Rapid Algorithm of Building Typification Based on Data Matching

An algorithm for building typification based on data matching between multi-scale databases is proposed.The algorithm is based on the dividing and conquering strategy.The whole map sheet is divided into several parts by road network.Each part is divided into several clusters by means of spatial clustering.The cluster is the basic process unit of building typification.The algorithm supports parallel process and is rapid,effective and adapted to Web mapping.
