Urban Grid Geographic Information Public Platform System Structure Research And Trials

Along with the development of the Digital City pushed by nation, the variety of the information are fully used by the management of the city to serve the decision making, and used by the public to get information service based on GIS. Following the specialization and profession stages, the urban GIS(UGIS) is developed towards the stage of socialization. In that stage, the main function of the urban GIS is providing the information to public.Based on the above background, the paper analyzes the system design of Public Flat of Urban GIS Based on Grid, and validates the system by the establishing of the experimentation. The main content involves:1. Bringing forward the system of the Public Flat of Urban GIS Based on Grid and introduces the constituents of the system.2. Analyzing of the principle of the grid data partition, the capturing of the grid data, and the techniques of the coding.3. The Bringing forward the principle of the base frame urban geo information, the capturing of the information, the coding of the information and the organizing of the information.4. Establishing the system of the sort and coding of the public information, bringing the sort of the public information in the flat, the point of the information, the capturing of the information, the attributes of the information, the coding of the information and the organizing of the information.5. Analyzing the updating of the information and the security of the flat.6. The paper gave experimentation, established a Public Flat of Urban GIS Based on Grid, Based on that, the paper implemented the services to the public.Finally, the paper summarized the fruits and the lack, and viewed the contents of the more research.
