Study And Realization Of Spatial Information Service Management Platform

When traditional GIS information resource are extended to the Internet, rich data resource have been provided to users'demands, which are growing unceasingly. Along with more and more spatial information service that conform to the standard and are stable to use are published to the Internet, how to effective gain, manage and use these services is becoming a hot topic.Originated from "the research, development and integration of region spatial information resource sharing and service key technologies", which is the sub-topic of the national science and technology support plan project "the key technologies research, development and the application of digital area informationization technical service system", this paper does research on how to carry on unification management of the spatial information service, and provide the foundation platform and the technical support for the city spatial information resource development and use. The main research work are as follows:1. Design one method to gain the available space information service in Internet.One simply method to gain the available spatial information service in Internet is designed, these services including OGC service and Web service that based on WSDL. This method is to establish a service database through crawling, verifying and parsing these existing services.2. Propose a synchronized sharing mechanism of the spatial information service under distributed environment.In the network environment, there are many region spatial information service resources node, each node has the possibility to gain the different service information. Establishing the synchronized sharing mechanism of the spatial information service is help to reduce the work load of service search and the service information reorganization, and raise the system efficiency.3. Realize a publish system of spatial information service.The goal of gain the spatial information service in Internet, is to use and manage these service information. A spatial information service publish system that can be visited by other users is be designed and realized, and this system will provide concrete application of inquiry and gain service.4. Realize and apply the spatial information service gain method, the service information synchronization sharing mechanism and the spatial information service publish system in actual project.Under the background of the project, the spatial information service management platform has been embedded in the "LGrid grid spatial information service management platform", and provided data support to the gridding of service.
