摘要
为实现海量土地资源数据多级网格管理和高效处理,设计了基于网格服务架构的土地资源多级网格化管理平台LR-MGSP(Land Resource Multi-Grid Service Platform),从网格任务分解、空间信息服务缓存和增量统计等方面探讨了提高平台处理性能的策略和方法.原型平台与非网格化的土地资源管理系统的性能对比测试结果表明,LR-MGSP达到了预期的目标,能够满足海量土地资源数据高效管理和处理的需求,也为其他行业开展跨机构协同处理海量空间数据工作提供了借鉴.
In order to manage and efficienly process massive land resource data based on multi-grid,the multi-grid service platform of land resource(LR-MGSP) that is grid service-oriented is designed,focusing on improving the processing performance in such aspects like grid task decomposition,caching service for spatial information and incremental statistics.Through the performance test comparing with traditional land resource management system,the desired objectives for LR-MGSP is achieved,the needs of efficient process of massive data of land resource is met,and provides new thoughts for other industries that needs inter-agency coordination processing massive spatial data.
