Architecture design of grid GIS and its applications on resource sharing

Grid_GIS is an SOA (service-oriented architecture) based grid GIS system for data and function sharing in multiple application domains. The Grid_GIS adopts a Super P2P (peer-to-peer) architecture to realize the distributed storage, query processing and dynamic integration of data and functions resources. The domain ontology knowledge and reasoning rules are used to support the semantics-based intelligent query. Standards-based Web services, utilizes "push" mode to realize monitoring of resources. According to the monitor resource parameters to realize rapidly resource distribution. utilize WS-Security expansion to achieve grid security, gain compatibility with other grids and improve compatibility with other platforms. At last make a data sharing and transformation experimental system based on LAN, test the system's feasibility and effectiveness.
