Research on Spatial Data Interoperability in Spatial DATA Grid Environment

Aiming in the data interoperation such as access and sharing of heterogeneous spatial data in distributed system, grid technology was brought into spatial information service, and a complete architecture of spatial data interoperability in Grid environment was proposed. We analyzed and designed spatial data management, access and interoperability in the architecture, and offered possible ways for spatial data user to share, analyze and process the distributed data resources. In the end, a prototype system is built based on Globus Toolkit and OGSA-DAI, proving the architecture and methods brought up above are practical.
