The Research And Application Of The Key Data Services Technology In The "One Map" Platform Of County-level Land And Resource

With the development of information system construction, land and resource management department are making rapid progress on data management and application system. Therefore, with the development of the computer technology, 3S technology, and the improvement of data acquisition and collection capabilities, the requirement for various types of data, and cooperation among applications become more and more pressing. Construction and digging the potential value of land and resources information sharing services is the focus of our departments in the new era.Since data services on the county-level come up against a series of problems, for example, their weak technical supporting system, obstructed internal and external information communication, and many limitations within the applications. To solve these problems, in this thesis, by integrating spatial database, network communication,and GIS technologies, we explored the data services technology on the county-level "One Map" Platform to examine the patterns of land and resource data organization and management, and implementation process of data services.In this study, we constructed the core information service platform of "One Map" on the base of Service-Oriented Architecture(SOA) and Windows Communication Foundation(WCF), in order to achieve uniform data management and transparent access. By design and realization of the integrated management information system,“One Map”, for county-level land resources, we have successfully achieved the exhibition of spatial data, statistical analysis, and land services etc. Through “One database & Two systems”, we have improved the degree of information communicationin county-level land and resource, optimized the information assurance, and improved data management and sharing services.
