摘要
为了在一定程度上满足某些用户在基础地形图更新周期内对电子地图数据更新的需求,建立了北京市多源空间数据库,并以此为基础开发了北京市多源空间数据库生产服务系统。该系统以现有基础测绘成果数据为基础,结合其他空间数据,进行空间数据包括各种专题数据的生产加工,实现数据的快速更新。本文介绍了北京市多源空间数据库生产服务系统建设的目的意义、关键技术、系统功能以及使用情况,并详细论述了北京市多源空间数据库生产服务系统的工作区管理、操作过程自动记录等特点。
The multi-source spatial database of Beijing is designed to meet some users＇ demands for the digital map data updating while the basic topographic map is in the updating circle. Based on the basic topographic map database, combined with other spatial data, the production-service system of multi-source spatial database of Beijing has been developed to process various spatial data and thematic data, thereby accelerating the updating of the spatial data. This paper aims to introduce the purpose, the key techniques, the function and the use of the system, and detail some characteristics of the system such as the management of workaround, the automatic recording of operational process, etc.
