摘要
首先分析了网格兴起的背景和国内外在网格领域的研究进展,并结合空间信息自身的特点提出了空间信息网格的概念,接着建立了空间信息网格三层体系结构,最后阐述了空间信息网格的元数据目录、存储资源代理、互操作技术、智能体技术、空间信息网格服务以及安全机制等关键技术。
In this paper, firstly, the background of thriving Grid research and the proceeding of Grid research in China and abroad are analyzed. Combined with the characteristic of spatial information, the concept of Spatial Information Grid (SIG) is presented. Then the Three-Layer Spatial Information Grid Architecture Model is established. At last, some key technologies of Spatial Information Gird such as metadata catalog, storage resource broker, interoperability, agent, spatial information grid service and security are discussed.
