摘要 分析和比较了现有空间数据集成方法,指出面向地理数据服务的空间数据集成是目前构建空间数据集成系统最理想的方式;从查询应用的角度分析了面向地理数据服务的空间数据集成关键技术,总结了已有的研究成果,指出了空间数据集成技术当前研究的热点问题和进一步的研究方向。 This paper analyses the existing methods for integrating spatial data and points out the spatial data integration oriented Geo-data services is the best one. The paper gives the key technologies for the geo-data services oriented spatial data integration system from the perspective of query application, and figures out the future directions for building a spatial data integration system with efficient query process performance.
