Research And Application On GIS Integration Based On Web Service

As the development of Web Service technology, it has provided a new opportunity for the traditional electron government affairs. It changed the data and the information's process of being gain, transmission, issue, sharing, application, and so on in the electronic government affairs. It has formed a specially research and application domain which GIS is applied in the electronic government affairs. According to the domestic and foreign information expert's statistical analysis, the governmental agency's comprehensive business management and the assistance decision-making take part of 80% of the geography space orientation and the spatial auxiliary decision-making system. As an important constituent of the country's information resource, foundation of the geography data is also other society's statistical information carriers and space orientation platform. Therefore, mapping high technology has already become the core strut technology of the national information and the electronic government affairs construction. First, the dissertation conducted a thorough research about the system integration theory, the geographic information system, Web Service and so on. Afterwards, the dissertation launches a discussion to the present hot spot domain -electron government affairs and it's correlation theory, analyzed it's function and superiority at the electronic government affairs which GIS is based on Web Service. In this foundation, it concentrated to the essential technology -GIS system integration theory, and conducted a concrete research. Then, the dissertation discussed the superiority which Web Service technology was used in the GIS data and the function sharing fields, it proposed a new GIS integration model structure which was based on Web Service, it also proposed a new basic data flow, as well as a operating system structural framing. Finally, the present paper applies the model in a concrete example, designed and has realized "the Zhangpu County forestry administration management information system", at the same time, it has confirmed the model's feasibility. Through the integration to the GIS services, the dissertation has provided a model structure which one kind may profit from.
