Design And Implementation Of Digital City Geographic Information Public Platform

The "Digital Earth" attracted national attation since it was be proposed.Then,"Digital State","Digital City","Digital Community" were proposed,and be setted up."Digital City" is a key of our contry’s high-tech and economic development. It is inherent requirement to accelerate urban modernazion."Diagital City"construction is the essence of geospatial information to establish the city as the core information services and share system.When the "Diagital City" was built,it will chang the traditional way of production and operation and the way of people’s lives.And the city’s economic and social benefits for national information were improved too.In this paper, the "Digital Wenzhou" key technologies and method are discussed.And Take a research to achieve "Digital City" geospatial resource share method.Based on the demand research,the problem of "Digital WenZhou" system was ansysed. About "Digital Wenzhou", We take researches about the shared services platform,basic spatial database,metadata,service and application management.Then design four layers(Support Layer, Data Storage Layer, Service Interface Layer, Application Layer) base on it.As the basic for development of a data management subsystem,online calling module,zero assembly module,the standard service module,operation and mainternance management module,and ultimately the "Digital City" sharing platform.Based on the structure, the construction of multi-scale, multi-resolution, multi-species geospatial data framword to unify the spatial location and basic geographic information public platform for Wenzhou geographic information resources provide the basic for development and utilization of platforms and technologies protection,and by sharing resources,exchange mechanisms and relevant normative standards system implementation.
