Application of Grid Service on Geology Survey Spatial Data Service

Bringing the service grid into the geological survey spatial data service area can greatly improve the processing speed of geological data, and can solve cooperation issues in isomerous environment and the data sharing problem on wide area network (WAN). This paper discusses the issues of data storage, organizing and sharing on spatial data service in geology survey, proposes the technology frame for applying the grid technology to geological survey spatial data, this frame based on on concepts and technologies from the grid and web service communities, the frame defines network resource layer, network service layer and application layer. Service oriented and extendable are the characteristics of the frame. Based on web services description language (WSDL) and SOAP+HTTP protocol, it has built an architecture which is fit for the geological spatial data grid, and implemented the geological survey spatial data service application system. The results show that applying grid technology to geological spatial data service area is possible. It provides advanced resource sharing mode from the aspect of data sharing and computes resource interoperation on the network.
