%X Grid_GIS was an SOA based grid GIS system for data and function sharing in multiple application domains.Grid_GIS adopted a super P2P architecture to realize the distributed storage,query processing and dynamic data integration.According to domain ontology knowledge and reasoning rules,realized the semantics-based intelligent query.Based on standard Web services,it using push mode to realize the resources monitoring.According to the system state and the communication between tasks,adopted cost constraints adaptive scheduling algorithm to realize dynamic scheduling and loading balance.Utilized the WS-Security expansion to realize the grid security,guaranteed the grid security and realized with other platform compatibility.At last,made a data sharing and transformation experimental system based on LAN,tested the system's feasibility and effectiveness.
