Research on the Sharing and Interoperation of Geospatial Information Based on the Combination of GRDI and OGC

The research on the sharing and interoperation of geospatial information is always a hotspot in GIS field. Many methods have been proposed such as data format transform, data direct access, Web GIS and data interoperation. These technologies have made great progresses in the sharing and interoperability of geospatial information. But there are many unconquerable problems such as the process of the distributed massive spatial data, providing integrated and transparent services, capability of geocomputing and migration of geospatial information services for users. In this paper, we combine grid and OGC web service to research how to realize the sharing and interoperation of geospatial information. We introduce the grid technology and OGC web service specifications. Then we design the architecture of integrated Grid and OGC. At last based on grid middleware Gloubs Toolkit 4 and Java technology, we develop and deploy Grid map services which encapsulate OGC Web Map Service.
