| 摘 要： | 分析了当前地籍信息系统在多服务器协同与海量空间数据共享和互操作中存在的问题，剖析并引入群集(Cluster)技术，优化设计了多层次多PC服务器群集体系架构的地籍信息系统，并结合常规海量分布式空间数据库的多项管理策略，发展了一套基于群集的多缓冲区策略和双机互备等多服务器海量空间数据管理技术，充分发挥了群集技术在高性能运算和高可靠性多服务器架构等方面的技术优势。在浙江省桐乡市的基于群集的地籍信息管理应用中，验证了群集地籍信息平台的整体性能优越性。

| Abstract: | Analysis for the need that should be resolved in new geographic information system developing, deeply studying and analysis for cluster techniques were taken. To meet special request for present management of vast quantities of spatial data in net, an optimal multi-level PC servers architecture in GIS with clustering techniques was designed to take full advantages of high performance computing, high reliability and other cluster features. Integrated with general spatial database management strategies, a new type of distributed data management techniques such as high spatial locating, multi-caches strategies cluster based were developed. An application in Tongxiang tests the high performance of whole GIS platform. |
