基于数据仓库的GISOLAP及其应用实践——以PSGIS为例

GISOLAP & IT′S APPLICATION BASED ON DW ——take PSGIS for Example

怎样提高基于海量数据的大型GIS应用系统的快速分析和反应能力是当前GIS领域所面临的重要问题之一。文中提出了GISOLAP的思想 ,并就GISOLAP思想及其相关技术 :数据仓库、基于数据仓库的OLAP以及GIS构件技术进行了阐述 ,并介绍了GISOLAP在城镇公安综合管理信息系统中的应用。

It′s one of the important problems in GIS area to improve the large scale GIS application systems′ fast analyzing and responding ability, which are based on quantities of data. In order to solve it, this paper put forwards GISOLAP concept and expatiates on GISOLAP concept and it′s relative technologies: data warehouse, OLAP based on data warehouse and GIS components. This paper also introduces its main applications in PSGIS.
