The Design And Implementation Of Digital Jiujiang Geographic Information Public Service Platform

With the rapid development of geographic information technology and computer technology, and the popularity of geographic information technology in the digital city construction, making the application of geographic information technology in more and more fields, team construction of digital cities are also growing, and achieving good benefits for the various organs and units of construction project. Although digital city construction has obtained some achievements, because of too fast digital city development in our country, resulted data quality in the construction is not high, point of interest data timeliness in the process is not high, and a series of problems such as nonstandard service interface.Faced with these problems, this paper through the analysis of Jiujiang's existing data and user groups, detailed designing the overall framework?database building program and portal content etc for digital Jiujiang geographic information public service platform. Platform based on the MVC framework adopted the current popular rich client technology, and integrated with the GIS technology, AJAX technology, Web service and other technology, platform aimed at achieving geographic information service platform of resource sharing, improving the unit production efficiency, avoiding repetition of data of production and construction.This paper achieved the design and realization of digital Jiujiang geographic information public platform, the main research work is as follows:(1) Analyzing the present situation of construction of digital cities, elaborating the existing problems and shortcomings in the process of the construction of digital, and the purpose and significance of the construction of digital city.(2) Studing the information?comprehensive demand analysis and the key technology used in digital geographic information public service platform Jiujiang Completing the overall architecture design of the platform?the standard system construction of the platform,and the design of the system running environment, and detailed designing the platform data sharing and publishing system, portal website construction.(3) Describing the general ideas of public service platform, introducing the realization of the basic functions of the system and the key code, and based on the platform of Jiujiang real estate sales network system.
