A Design of the Architecture of Geospatial Information Collaborative Service in Spatial Data Grid Environment

The collaboration and cooperation of services in heterogeneous, distributed grid environment is dynamic and diverse because of the distributed resources and disparate functions. Therefore, the collaboration and cooperation can be technically challenged by the need of users who want to control and manage various services, running on different platforms. In this paper we brought forward a design of the architecture of geospatial information collaborative service in spatial data grid. The WSRF-based services in the architecture provide a transparent way to select the appropriate spatial data service providers in a dynamic spatial data grid and hide the complexity of the interface and scheduling strategy from users to coordinate those required services to perform guarantees and lead to better spatial resource sharing and significant service performance.
