摘要
供应大比例尺地形图是城市测绘资料管理部门的基本职能。文中论述了在ARC/INFO基础上,以1:25000比例尺地形图上的点、线、面地物为索引,查询北京市1:500~1:10000各类比例尺地形图图幅号的算法。实验表明系统是实用的。
Providing large scale topographic map is the necessary function for management of urban surveying and mapping. It is argued the algorithm to query topographic maps code at various kinds of scale. based on ARC/INFO software. indexed in the point, line, and area features on topographic map at scale of 1: 25 000. the experiments indicate that the system is useful.
