摘要
为解决无限的空间地理信息与有限的数据显示窗口之间的矛盾 ,需要“数字地球”无级比例尺信息综合技术 .空间数据仓库为数字地球提供了管理异质、异构海量信息的功能和面向数字地球的高层应用服务 .而面向无级比例尺的空间数据库 ,为解决无级比例尺的信息综合提供了可靠的应用支撑 .本文就解决无级比例尺信息综合而建立的空间数据仓库提出一个基本的方案 ,并探讨了几种格式的空间数据索引 .
To resolve the conflict between the infinitely spatial geographic information and finite data view window, we need the digital earth's infinitely variable map scale information generalization technology. The spatial data warehouse provides the function of managing the heterogeneously magnanimous information and the service of digital earth oriented high level application. The infinitely variable map scale spatial database provides the reliable application support for infinitely variable map scale information generalization. This paper presents a basic project for spatial data warehouse that can resolve the problem of infinitely variable map scale information generalization. Several different format spatial index are also discussed.
