摘　　要：大比例尺数字化地形图在城镇建设中起着重要的作用,而传统地形图缩编技术效率较低。本文以北京市1∶2000数字化地形图缩编1∶10000地形图为例,充分利用GEOWAY GeneMap平台的缩编功能,采用基于规则库的一致性制图综合和交互式制图综合相结合的方法,缩编作业效率比较高,减轻了作业强度,提高了作业精度,为大比例尺地形图缩编提供了一种新的思路。Map generalization is a procedure involving much intellective reasoning action, with very wide domain. It is also a difficult problem in the field of cartography in the world. This paper makes a study on the interactive and rulebased digital generalization, and a map generalization environment for large scale topographic map is designed and realized. A number of tests have proved that map generali zation can be successfully and interactively done with the cooperation of human and computer if the procedures of map generalization are wisely decomposed. Compared with the traditional manual meth- od, this map generalization can shorten the working time to 1/4 or even. Besides, the work will become less intensive with higher precision.
