中国地质调查信息网格平台构建和地质图数据服务的实现

对组成中国地质调查信息网格平台的结点计算池的构架、机制和组成结点计算池的资源聚合器、元服务、智能服务引擎的概念进行了阐述,提出了结点自治的方案;基于资源共享、虚拟化、Web服务等创建了基于元数据服务、栅格流服务、矢量地图服务、三维可视化服务等多模式的地质图数据服务。目前已初步构建了中国地质调查信息网格,连通10个结点 ,为地质图空间信息共享和应用提供一种全新的技术解决方案,取得了良好的实际运行效果。

Building of China Geological Survey Information Grid Platform and realization of geological map data service

This paper deals with the framework and mechanism of the node computation pool which composes the platform of the China Geological Survey Information Grid, the concepts of resource aggregation, meta-service and intelligent service engine which compose the node computation pool and conclude node autonomy. The geological map data service system is described in terms of resource sharing, virtualization and web service, which is characterized by multi-hierarchy such as metadata service, raster data, vector data and 3D visualization. China Geological Survey Information Grid has provided a new solution for sharing and applying geological map spatial information; so far, it has connected 10 nodes preliminarily, and is performed properly and effectively.
