    • 摘要: It is the research focus of geographic information industry applying grid technique in the field of geographic information and building grid geographic information system for the purpose of sharing and cooperation of geographic resource information. Web service specifications established by the Open Geospatial Consortium which are the widely suppoited interoperable standards ofgeospatial data, are incompatibie with grid technique specifications, making it difficult to be integrated and managed under the grid framework. This paper probes into the related specifications of OGC data service WMS, WFS, WCS and OGSA - DAI grid middleware technique, puts forward a plan to extend OGC data service to OGSA-DAI data resource. encapsulating WMS, WFS and WCS as WSRF-compliant grid resource in order to access, integrate and manage distributed heterogeneous geospatial data under OGSA framework. The proposed plan provides a method to integrate OGC service into grid environment which is easy to carry out and can be a helpful reference of related technological development.%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。OGC制定的网络服务规范作为得到广泛支持的地理空间数据互操作规范。与网格技术的相关规范存在许多不兼容之处,使得OGC服务在网格体系下难于集成和管理。文章研究了OGC数据服务WMS,WFS和wCS的相关规范和OGSA—DAI网格中间件技术,提出将OGC数据服务扩展为OGSA—DAI的数据资源的方案,将WMS,WFS和WCS封装为符合WSRF的网格资源,实现分布式异构地理空间数据在OGSA—DAI框架下的访问、集成与管理。此方案提供了一种将OGC服务集成到网格环境中的方法,比较容易实现,对相关研发工作的开展具有很好的借鉴作用。
