摘要
日益复杂的网络应用对空间信息服务提出了状态管理的需求。WSRF规范提供了有效的Web服务状态管理机制。基于WSRF规范构建有状态的空间信息服务是实现高效、复杂的服务互操作的基础,也是实现网格GIS必要手段。分析WSRF规范对空间信息服务的有力支持,以Web要素服务为例探讨了基于WSRF的空间信息服务构建、访问和部署方法,并给出了具体实现。
The complication of network application requires the state management of spatial information services. WSRF specification provides effective Web service state management mechanism. To build stateful spatial information services based on WSRF specification is helpful for high performance and complicated services interoperability, and is also the necessary means for grid enabled GIS. The powerful supporting of WSRF specification for spatial information services was analyzed, the WFS was taken for example to introduce the implementation, access, and deployment of spatial information services state.
