The Design And Implementation Of Urban Space-based Information Service Platform

Since reforming and opening-up, our country has achieved great achievements in everyrespects, Along with the development of the society and ecjonomy, so inorder to meetgovemment eomprehensive management efficiency and raise the level of publie life,further improving the eity informatization level appears especially urgent.While theconstruction of "Digital city" is its important constituent and forms. Digital city is theinformationization of the city,the sharing of information resources, and create theconditions for information technology to stimulate industrialization,and the nationalinformatization and will drive the development of modern,City digital and information isthe city social and economic development of the important driving force, is the nationalsociety and rapid development of the economy and the strong force,"Digital city"hasbecome the subject of urban informatization construetion.Economic information,globalization, knowledge is in the ascendant, China's modernization has entered the newstage of scientific development, digital city construction will cause more and moreattention, with great development space and demand, and the construction of "Digital city"in essence is to establish the city information service and sharing system,using thefundamental geographical spatial data as the eore.In2006,Shenzhen "eleventh five-year"information plan will "digital Shenzhen"construction as an important project,In August2007,the "digital shenzhen space foundationinformation platform"overall design scheme of through the expert,platform in turngradually develop the purpose construction work, This paper launched researchs on thisbaekground, and take digital shenzhen space information platform construction project asan example.The main contents researched in this paper are as follows:①This paper introduces digital shenzhen construction the relevant techniques.②According to the first phase of the shenzhen existing digital shenzhen space base ofthe present situation of information platform, Study and redesigned the overall systematicframe,function structure and database structure of Shenzhen public service platform.③Digital shenzhen space information platform of frame structures based technology USES is the plug-in type technology, custom made independent deployment, reusable,second development of the rich client GIS system framework. The plug-in technology tofacilitate the expansion of the after-platform content, only to the new content as a pluginloading can come in.④Unified user permissions authentication technology.Access control and managementof the platform provides access system,undertake unity user permissionsauthentication.Including the single point login and authority centralized management twoaspects.The primary research results of this paper are as follows:1.Based on SOA structureconcept,the Paper have designed the architecture strueture,operation structure,functionstructure and database structure of the digital shenzhen space foundation informationplatform.2.Use technology to map the generation of ArcGIS and use the ArcGISServertechnology to the release of data services and updates.3.By calling the data service realizemap, the surrounding search,search,project service bus inquires GIS function.4.Theconstruction of digital shenzhen made at some key technologies,through the technologicalverification and give the solution.
