| 摘 要： | 道路网络自动综合是地图综合的主要研究课题。本文通过引入对偶拓扑理论建立了城市道路网络的对偶拓扑结构,并将道路的重要性表达为路网中所有道路的重要度贡献的总和,进而提出了一种道路网络自动综合方法。实验表明,本文方法可以较为合理地选取路网中相对重要的道路,所选路网保持了原始路网的整体形态及拓扑连通。

| Abstract: | Automatic generalization of road networks is the main topic of map generalization .This paper introduce the dual topology theory to construct the dual graph for road network , define the road importance as the sum of importance contribution of all roads in the entire network, and propose a automatic generalization method for road networks .The results show that the proposed method can rea-sonably select the important roads , and the selected road networks retain the global structure and topological connectivity of the original road network . |

| Keywords: | road network map generalization dual topology node importance |
