大比例尺地形图交互式综合系统数据库平台的建立

在论述交互式综合环境研究的重要意义及大比例尺地形图特点的基础上,采用人机协同的地图缩编方式,将复杂的地图综合过程分解,合理地进行人机分工,设计与实现了大比例尺地形图交互式综合系统的数据库管理平台。实践证明,利用该数据库平台建立的综合系统适用于人机协同的作业方式,可以顺利地、交互式地完成地图缩编工作,减轻了作业强度,提高了作业精度。

Construction of Database Platform for Interactive Generalization on Large Scale Topographic Map

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 digital generalization,and an interactive map generalization environment for large scale topographic map is then designed and realized. A number of tests have proved that map generalization 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 method,interactive map generalization can shorten the working time to 1/4 or even.Besides,the work will become less intensive with higher precision.
