摘要
传统上,电子地图数据主要来自各个比例尺的地形图,而各个比例尺的地形图来自不同测绘部门,导致数据的一致性和实时更新变得困难。为了解决电子地图数据的现势性和产品规则不一致问题,提出一种通过自动缩编建立多尺度城市电子地图数据库的方法。该方法旨在实现电子地图数据的多尺度同步更新,将各个比例尺的数据整合到一个统一的数据库中,从而提高电子地图的现势性和用户体验。这种方法能够更好地满足用户对电子地图的需求,并促进电子地图技术的发展。
Traditionally,electronic map data primarily comes from topographic maps at various scales,obtained from different surveying departments,which leads to difficulties in maintaining consistency and real-time updates of the data.To address the issues of timeliness and inconsistent product rules in electronic map data,this paper proposes a method for establishing a multi-scale urban electronic map database through automatic generalization.The method aims to achieve real-time synchronization and updates of multi-scale data in electronic maps by integrating data from various scales into a unified database,thereby enhancing the timeliness and user experience of electronic maps.This approach can better meet users needs for electronic maps and promote the development of electronic map technology.
