Research of data index service in spatial data sharing platform
空间信息共享平台中数据索引服务的研究*

In order to eliminate the spatial information silo,this paper set up the spatial data sharing platform through the research of open grid services architecture.Clients could get access to the data in the virtual organization by the platform's grid services.In order to improve the performance of index service,it proposed a new R-tree's algorithm.During the process of splitting one node,it checked other's nodes to provide appropriate accommodation for the new node.As a result,frequently splitting could be avoi...
