Design and Implementation of Registry Center of Geospatial Information Service in Grid Environment

Service oriented architecture(SOA) is the development trend of interoperability and integration of geospatial information.Grid computing is a means to implement SOA,which has many virtues,and provides a new idea to implement sharing and integration of geospatial information in wide domain.A scheme to construct geospatial information service registry center is presented.Based on OGSA,WSRF and OpenGIS series standards,the middleware and framework provided by Globus Toolkit 4,that scheme can resolve the sharing problems of geospatial information service in grid environment,at the same time of assuring the standard compliance.
