| Abstract: | Based on the production practice,this paper puts forward a method of generalizing 1∶ 500 to 1∶ 2 000 topographic maps.1∶ 500 to 1∶ 2 000 topographic map generalization platforms are developed on Qinghua Shanwei EPS 2008 geographic information work station,in order to complete complicated editing task of topographic map through graphic primitive comparison conversion and cartographic generalization of 1∶ 500 EDB data source,whereas cartographic generalization is implemented through automatic batch processing,human-computer interaction combined together with manual editing. |
