空间信息网格SIG:新一代的空间信息基础设施和服务框架

Spatial Information Grid:A New Generation of Spatial Information Infrastructure and Service Framework

空间信息数据量大、处理复杂、难以共享的问题对其研究和应用提出了挑战。空间信息网格(Spatial Information Grid,SIG)作为创新性的网络空间信息基础设施和技术体系,集成并拓展信息网格、空间信息系统、Web服务等前沿技术,以"服务"为中心,实现一体化、智能化的空间信息获取、存储、组织、分发、分析处理、集成与应用,实现基于网络的空间信息资源共享与空间信息服务。

The applications and research of spatial information are generally considered to be a challenging problem due to the excessive voluminousness, complexity of processing and difficulty in sharing of spatial data. As a novel web-based infrastructure and technology system of spatial information, Spatial Information Grid （SIG） integrates and extends many advanced technologies, such as information grid, spatial information system, Web services, and etc. To implement sharing and integration of spatial information, SIG takes ＂service＂ as its technical core, and establishes a unified intelligent environment to acquire, store, organize, distribute, analyze, aggregate. and apply spatial information.
