摘　　要：将网格技术应用于地理信息领域,构建实现地理信息资源共享与协同工作的网格地理信息系统,是目前地理信息行业研究的热点之一。OGSA-DAI(Open Grid ServicesArchitecture-Data Access and Integration)是网格环境下进行数据访问与集成的网格中间件技术,为了实现网格环境下地理空间数据的访问与集成,提出WSRF-SDAI(Web ServicesResource Framework-Spatial Data Access and Integration)的概念,并介绍了WSRF-SDAI的实现方法。WSRF-SDAI的含义是基于网格体系结构WSRF进行地理空间数据的访问与集成,是OGSA-DAI在地理信息领域的应用与扩展。Applying grid technology in the field of geographic information,building the grid geographic information system to achieve geographic information resources sharing and cooperation,is one of the research focuses in geographic information industry.OGSA-DAI(Open Grid Services Architecture-Data Access and Integration) is an innovative solution for distributed data access and management in grid environment.To achieve geospatial data access and integration in grid environment,gives a conception of WSRF-SDAI(Web Services Resource Framework-Spatial Data Access and Integration),and introduced its realization.WSRF-SDAI's meanings is making geospatial data access and integration based the grid architecture WSRF,it is OGSA-DAI's application and extension in geography information area.
