DESIGN AND REALIZATION OF MULTI-SERVERS CADASTRAL INFORMATION SYSTEM CLUSTER BASED
针对新型地理信息系统开发需求，研究集群技术，设计多级PC服务器架构，结合空间数据库管理策略，开发分布式数据管理技术，并在桐乡市应用中验证了平台的高性能。
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.
