基于EPS平台的地形图缩编方法研究

摘要

结合生产实际,提出了1∶500-1∶2 000地形图缩编处理方法.在清华山维EPS 2008地理信息工作站上定制开发了1∶500-1∶2000地形图缩编平台,对现有1∶500 EDB数据源进行图元对照转换和制图综合完成复杂的地形图的编辑工作,其中制图综合采用全自动批处理、人机交互式,以及手工编辑相结合的处理模式.%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.
