摘　　要：　在支持开放式地理数据互操作规范的基础上,针对OLE/COM环境,提出了一种基于组件的OpenGIS系统结构,讨论了基于组件的OpenGIS涉及的相关技术,重点探讨了它的核心组件———服务组件模型结构的设计和基于OLEDB的一致访问接口技术。实践证明了开发基于组件的OpenGIS具有优越性。This paper presented a componentbased Open GIS architecture for OLE/COM environment. The system was designed to conform to the international standards proposed by OGC. Here, discussed the technology about Open GIS, and emphatically disserted the design of the core componentsOpen GIS service component and access interface based on OLE DB. The advantages of componentbased Open GIS were proved by the practical application.
