长春市大比例尺地形图缩编方法研究与应用

Research and Application on Contracted Compilation Method for Large-scale Topographic Map in Changchun

大比例尺地形图作为数字城市基础地理信息系统的主要空间数据,在城市规划管理、交通、公众服务等众多领域有着十分重要的作用。将已有比例尺地形图进行缩编得到需要的比例尺数据,避免了不必要的重复数据采集,节约了资源与成本,也缩短了成图周期,具有重要的意义。本文研究在MicroStation 95环境下运用MDL语言编程实现大比例尺地形图的自动化缩编,并将其用于长春市1∶500、1∶1 000比例尺的全要素地形图缩编为1∶2 000地形图,取得了较好的效果。

Used as a urban basic geographic information system,the large-scale topographic map is a major space-based data.In urban planning management,transportation,public services and other fields,it plays an important role.After contracted compilation from known scale map,we can get new scale data we need,which can avoid unnecessary repeated data collection,save resources,short the map generation period and has important significance.This paper deals with automatic method for large-scale topographic map under MicroStation95 using MDL programming language,and was applied to contracted compilation for Changchun large-scale topographic map from map scale 1：500,1：1000 to 1：2000,good result was obtained.
