摘　　要：1∶500与1∶2 000地形图是城市基础地形图,由1∶500地形图缩编成1∶2 000地形图是1∶2 000地形图制作的重要手段之一。在EPS平台,对1∶500地形图进行缩编的方法分为2类:对制图综合指标明确的要素采用全自动缩编模块处理;对于关系复杂、综合智能化较高的要素采用人机交互摸式处理。该制图综合方法的自动化程度高,已在生产项目中得到实际验证。1∶500 and 1∶2000 scale topographic map is the city basic topographic maps,topographic map downsizing from 1∶500 scale is one of 1∶2000 scale topographic map important production means.In the EPS platform,1∶500 scale topographic map as base map was generalized from two sides∶ those elements with clear generalization indexes were processed by automatic downsizing modules;other elements with complex relationship and more intelligent generalization were processed by interactive mode.This generalization means was higher automated,and had been used in actual projects.
