| Abstract: | The middleware is one of the important key technologies of the Geospatial Information Grid. The propose of the research is to provide the users with the virtual machines which have the same programming interface, and support to solve complex application problem and various resources sharing on lntemet. The grid middleware of geospatial information needs to be designed to have the functions such as resource dynamic monitor, heterogeneous node shield, optimizing the resource selection and working in coordination with calculations. The component model of grid middleware in geospatial information include resource-monitoring modules, calculation service modules, grid security modules, fault tolerance modules, information service modules and application dispatching modules. |
