Study on interoperability in synchronous cooperative GIS based on message queue

For the requirement of consistency,high response and convenience of sharing spatial data in synchronous cooperative GIS,we proposed a way,which recorded collaborator GIS operation by message,and built the message queue for storage,dispense operation's message to realize GIS cooperative operation,with geographic information service technology after analyzing the current research results of interoperability in synchronous cooperative GIS.Firstly,we classified GIS operation types due to its characteristics,provided a principle of GIS operation priority evaluation and established transformation mechanism for GIS operation in collaborative environment.And then,we also discussed the description model of GIS operational message combined with the character of geographical information service,designed the rule of GIS message enqueue and dequeue operations,and constructed a cooperative GIS interoperability framework oriented geographic information service.Finally,we implemented a prototype system to verify the method.
