【摘要】 本文结合我国目前“数字省区”空间信息共享建设对于空间信息网络表达的需求 ,深入分析了空间信息共享系统中多种空间信息的网络表达问题 ,以及实现共享空间信息网络表达所需要解决的 3个基本问题。研究了基于 XML 的空间信息网络表达实现技术。该研究对于空间信息共享系统中实现空间信息网络分布式表达和系统共享空间信息的潜在价值有重要意义。最后通过“数字省 (区 )”建设的实践 ,实现了该研究成果的应用系统。更多还原

【Abstract】 To meet the demand of spatial information representation through network in the spatial information share system of "Digital province" and "Digital City", this article analyzed the problem of spatial information representation on network.Then solutions to the three problems and the technique of spatial information representation based on XML are stated in detail.The research has great potential in expressing spatial information of spatial information share system.Finally combined with the practice of "Digital province" in China, we carry out the application system based on the research.The application validates the feasibility of our research result.更多还原
