摘要
网络在城市地理信息系统的构建过程中越来越重要,信息资源正从单纯的自供自给的封闭模式发展成为内部数据加外部数据模式.在研究网格计算、空间元数据、开放网格服务体系及互操作等技术基础上,利用Wrapper/ Mediator方法给出基于开放网格服务体系(open grid service architecture ,OGSA)城市空间信息共享技术的总体架构.该框架解决了多源系统间的互操作问题,为城市地理信息系统建设中空间数据共享提供一种全新的理论指导.
The network has become more and more important in the construction of urban GIS, meanwhile the use of information resources has changed from closed mode to open mode accordingly. Using grid computing, spatial metadate, OGSA (open grid service architecture) and interoperability, we designed a general structure for urban spatial data sharing. The structure is based on Wrapper/Mediator method and can resolve the interoperability problem of multi-source sysem. As a result, the theory can be uesd to guide the urban GIS construction for data sharing.
