摘要
从网格概念出发,详细介绍了实现地质图协同编辑的SIG(SPATIAL INFORMATIONGR ID)空间信息网格技术,以及国家地质空间信息网格体系的结构和服务机制。国家地质空间信息网格采用万维网体系架构,以资源和信息共享、协同为主线,构成一个三层次体系架构。主要组成为:网格应用层、网格平台层、网格基础设施。并针对地质图空间数据共享与服务,设计了地质图服务流程,提供了信息查询、信息服务页面,展示了地质图的在线协同编辑。
Based on the concept of Spatial Information Grid,the paper introduces the SIG technique that used for the geology map's cooperative edition,and the system structure of the National Geology Spatial Information Grid(NGSIG) and service mechanisms.We adopted world-wide-web system configure to constitute a three-layer system structure base on the resources and information share and cooperative edition.The first layer is grid applying layer,second layer grid platform layer,and three infrastructure layer of grid.Aimed at the geology map,spatial data sharing and services also,we designed the geology map service process,provide a homepage for the information search and the information service to show the geology map edited on-line to be in conjunction with the editor.
