Research of Service Oriented Spatial Information Grid Technology

With the spatial informationpsilas continuous expansion and increased popularity, the amount of the spatial information grow explosively, and the current services have not meet the needs of accessing to and processing spatial information. This thesis starts with the grid technology, doing researches to services oriented spatial information grid technology, focusing on the basic model and security of grid, and researching on the spatial information grid which has the capacity of on-demand services, as well as can integrated organize and coordination process massive of distributed spatial information resources. At last, this thesis proposes a spatial information service architecture design model based on the environment of grid, and has carried on the preliminary discussion to the grid spatial information service, as well as has implemented a simple grid services model.
