GIS Application Research Of Dynamic Service Model Based On Jini

With the coming of the ubiquitous computing ,the appearing and development of new information technology and communication technology ,GIS has strided forward brand-new period. Introducing many new technology to GIS,this field would be provided with more vitality and energy. The Jini technique, the most outstanding representative of the universality calculation, makes information and service exist everywhere. The continuous development and evolvement of Jini must affect the direction of GIS development which has a close combination with technique of IT .This thesis studies the information service model based on Jini which is the important component of the dynamic service system with GIS for the foundation. It comprehensively applies a lot of currently related advanced techniques in domestic and international, including mobile position, short message communication, technique of JavaSpaces, the connection and platform development technique of mobile terminal, the technique of SOA structure and the latest technique related to Jini etc. The system designs the good agency service to resolve the problem of moblie users to register the Jini service, pass to act for the service management service information, satisfies the need that the resources limited equipments use latest Jini service by the management service information of agent service, and changes the service method of mobile application. In addition, the system provides the space information service for mobile customer referring to OpenLS specification .At the same time, the system also provides the friendly and abundant operation interface toward the Internet customer, provides service of dynamic registering ,monitoring, querying and related function of GIS so that people can enjoy more comprehensive and more convenient dynamic service.This thesis introduces and compares the SOA frame, WEB service and related technique of Jini, analyzes the wide development potential of dynamic service , and explains the applied possibility and advantages of the combination application of Jini and GIS technique firstly .Then, it puts forward the complete frame structure of dynamic service system based on GIS platform, and designs the system service mode and a realization of the function models. At last, it displays the running result and the application advantages of the dynamic service platform with the case of tenement, and puts forward a summary and outlook based on the above research.In a word, integrating of jini and GIS break a new application model.this paper's research will provide referrence and experience for development of application field in the future.
