Abstract: Obvious data consistency degree is not high in roads or habitation data, often in the presence of large geometric position deviation, which is not conducive to improve the accuracy and efficiency of road or habitation matching. A linkage matching method for road and habitation by using urban skeleton line network is proposed to solve this problem. The linkage matching imitates the human thinking process of searching for target objects by the signal features and spatial correlation when reading maps, regarding matching as a reasoning process of goal feature searching and information association transmitting. Firstly, urban skeleton line network is constructed by constraint Delaunay triangulation network; then, the topological relationship among road, skeleton line, skeleton line mesh, habitation is constructed; last, matching transmission model is established by the topological relationship. According to this matching transmission model, linkage matching is fulfilled, which contains road matching drives habitation matching or habitation matching drives road matching. The advantage of this method is that as long as there is an element of data consistency is good, can drive another element to obtain a very good matching effect, at the same time conform to the human cognitive process.

Key words: urban skeleton line network, road matching, habitation matching, linkage matching, topology relationship
