Abstract: Road network matching is an important prerequisite for the change detection and data updating of spatial database, and the matching of road networks at different scales is very important. In this paper, the existing algorithms road networks matching are summarized and analyzed firstly, and according to the problems and difficulties in the road networks matching at different scales, an algorithm integrating multiple matching techniques was designed. Based on the characteristics of road networks at different scales, the method of evaluating the structure of spatial scene was improved. The limitations of the algorithm based on stroke matching were analyzed for road networks data at the different scales, and the algorithm named “partial stroke matching” was put forward. The experiments indicate that the algorithm given in this paper can be used in matching of road networks at different scales, the effect of matching is good, and the running efficiency is high as well.

Key words: multi-scales, road networks, matching, partial stroke matching, spatial scene structure
