| Under the development tendency of WebGIS Widely applies in "the digital city", the questions which exist in the current city management, so many questions has occurred frequently, for instance, the well to cover losing, winter heating, road draining in rainy season and so on. This reflects that the city management level relative lagging has already restricted the city management further development, in the certain degree. Based on this kind of situation, this article the first part first introduced the new city management pattern-GBC (the G-government, the B- Business, the C-Citizen) based on the WebGIS. This city management pattern draws support from the modern information technology, conformities existing city management resources, strengthens residential and government's benign interaction, establishes the government to supervise coordinates, enterprise standard operation, the resident widely participation, performs its own functions, each its energy, mutually coordinates city management linkage mechanism, as well as impetus "service government" foundation.Taking The GBC city manages new pattern as the foundation overhead construction, taking the Beijing City Shijingshan area city manages platform construction as the project backing, the article third part analyzed GIS data management way and the data origin situation in the city manages platform construction. This also is our country facing with GIS data situation in the management platform construction in its city, at present. The article abstracts the city management data resources as the city part, the event GIS data resources. Its data management way is "the city grid management". The city management part data is "the city grid management" foundation, the city management part database is the core database of the city managed platform system, therefore its data quality directly relations city management platform function display. This article introduced the city grid management city part, plays the very good guarantee role on the controlling data quality question, and builds the foundation for the stable movement of the city manage platform database, simultaneously, for the WebGIS engine realization providing the basic GIS data resources.The article fourth part has carried on the further thin analysis to the GIS space data based on the GIS space storehouse request, and has carried on the detailed design to the platform database model in this foundation. The article has analyzed each table single detailed design of the spatial GIS data sheet and the non- spatial data sheet in the storehouse. Let us have the further perceptual knowledge to the GIS space database, which has laid the foundation for the next step of WebGIS engine realization.The article fifth part discussed the WebGIS engine realization technology. It is difficulty and emphasis. This part first to analyze each service in the platform based on the GBC city management pattern, then selected the platform business scope, and abstracted each GIS function module which the WebGIS engine would realize. And this function included the map roams function, basic geography analysis function, geography inquiry function, and has carried on the detailed design to these modules realizations.The article started from the city management new pattern design, defined the managed platform the bare bone, then analyzed the GIS data resources situation and the management way in the managed platform, and built the foundation for the core database GIS storehouse design of the Manage platform, then has carried on the detailed design to the database construction situation, finally through WebGIS engine designed, realized the GIS each function module of the city manage platform. The article design is a whole, from basic frame definition to resources preparation and storehouse design, finally GIS function module realization. The introduction of the city manages new pattern and the GIS engine realization have the certain reference value in other electronic government affairs service aspect!... |
