【Abstract】 In this paper, the present symbol base is used to symbolize the map features. The usual algorithms and knowledge database are analyzed during the symbolization of map features. The problems, which often occur in symbolizing the map, are studied in detail. The solutions to the problems are put forward by using the theories of spatial relation and Voronoi graph.更多还原
