摘要
在基于特性(Feature)的WEB GIS体系结构下,提出一个共享空间信息的解决方案。分布式技术减轻了服务器的负载,对象关系数据库技术解决了传统GIS系统中空间数据难以共享的问题,两级高速缓存技术提高了系统在网络环境下分布处理空间数据的性能。最后对解决方案进行了模拟实验,证明系统不仅能有效地共享多个GIS系统的空间信息,而且在性能上相对于传统GIS有很大的提高。
This paper put forward a solution which shares space information in WEB GIS system based on feature.Distributed system technology has lightened the load of the server,object relation database technology has solved the problem that the space data in traditional GIS system are difficult to share, two grades of high speed buffer memory technology has improved the system s performance of dealing with spatial data in the environment of network.Finally,this paper simulates the solution,testify that this system ca...
