| 摘 要： | 为了充分利用现有地理空间数据资源,降低GIS工程建设的成本开销和复杂度,本文首先对比分析了虚拟和物化两类空间数据集成方式,阐述说明了不同空间数据库之间的冲突类型以及相应的消解措施。从目前应用和研究现状来看,空间数据仓库方式是目前比较常用且可行集成方法,基于中介器/包装器的集成方式则是目前研究的热点,而集成过程中语义冲突的自动发现和消解仍是一个难点问题,尚需进一步的探索和研究。

| Abstract: | In order to fully utilize the existing geospatial data resource,reduce the building costs and complexities of GIS project,two kinds of spatial data material and virtual integration approaches were contrastively analyzed in the paper.The conflicts between spatial databases and the corresponding harmonizing technologies were discussed and explained.As viewed from the current application and research status,the data warehouse approach is feasiblely and widely used,the approach based on Mediator/Wrapper is the ... |
