| Digital city is the prospecting trend of the city informatization construction. Strongly supported by information science , City GIS has developed rapidly and been broadly applied in many government administrations. However, at the Beginning term of Digital City construction ,it lacked unified regulation of building GIS that cause the difficult of spatial data sharing and interacting in diverse GIS. Nowadays , one of the most significant research subjects related to Digital City is how to build a unified platform on which data can share and interact by making use of the established GIS .It is common that many GIS adopt diverse data structure and processing techniques to develop their system ,there are great differences between GIS system .Therefore, data regulation and system integration are main issues of this subject.The expatiation is shown in the paper firstly about the concept and framework of Digital city and comparative study of development of Digital city at home and abroad. On this basis, the essay discusses three following problems with the background of the build of the Digital Baoshan in Baoshan District.1. To analyze the problems in the build of GIS of Baoshan District.2. To propose a framework of constructing platform of spatial information sharing and interacting in Baoshan that include 3 layers of network of interacting and sharing data , application, spatial database .Furthermore this paper design the platform in function module based on this framework that include platform management,, data sharing on platform and data interacting on platform and platform security.3. To discuss the management and implementation of the project, including the organizational guarantee, project implementing management and the maintenance management based on software, engineering project management and so on.Baoshan District is constructing the fundamental platform of spatial information based on the framework and methods in the paper. |
