基于程序自动化设计思想大比例尺地形图人机交互式缩编的研究

The Study on Map Generalization for Large-Scale Topographic Map Based on Man-Computer Interaction

随着城市经济和社会的快速发展,作为城市基础用图的大比例尺地形图要求紧跟城市建设发展的步伐,而传统地形图缩编技术效率较低。本文以天津市1∶500比例尺地形图缩编1∶2 000比例尺地形图为例,通过充分研究各种应用在缩编中的方法,结合AutoCAD Map 3D平台的二次开发功能,采用人机交互式的方式,大大提高了缩编效率,为大比例尺地形图缩编提供了一种新的思路。

Along with the development of city economy and society,the large-scale topographic map that is for city＇s basic use must act in compliance with city construction,but the traditional map generalization is implemented with low efficiency.This paper proposes a plan of map generalization for large-scale topographic map.With the plan,the map generalization is implemented with a great efficiency.The plan is a new method and carried into execution on basis of AutoCAD Map 3D software platform.It is applied to the map generalization of the 1∶ 500 to 1∶ 2 000 scale topographic map.
