| 摘 要： | 在实际工作中,常常需要把大比例尺AutoCAD数据格式的数字化地形图缩编为小比例尺地形图。本文通过对地形图符号的分析,结合天津港1:500比例尺地形图缩编为1:2 000比例尺地形图的实例及地形图图示说明缩编的主要原则和缩编过程。

| Abstract: | In practice,it is very often to reduce and edit a large-scale map of AutoCAD format data to a small one.This article describes the principle and process of the reduction and edit by the analysis of the topographic symbols,and gives an example of editing Tianjin Port map scale from 1:500 to 1:2000. |
