The Design And Implement On The Topic System Architecture Based On The Online Mapping Service

With the digital city started across the country, the geography information resource is widly used and accelerated much by building the uniform and the urban NewMap Plat for government departments and the public with the steady geography service in time.The NewMap Plat provides the online mapping application service and the extensible space for various topic system applications.More and more departments need to build kinds of topic systems with their own specialty based on the NewMap Plat.In this paper,firstly,it researches the theory and some technology relatively and designs an architecture of the topic system based on the online mapping service.Then achieving the building about the Qianjiang planning query system following the idea of this architecture by transfering, extending and combinating the online mapping service.The goal of the design of the topic system architeture based on the online mapping service is to design a universal architecture on the foundation of th online mapping service.The architecture can provides a base structure, cuts down the cost,increases the times of using.At the same time,it can solve the problem about the data collecting,updating, application and conformity,and managing for realizing use of resource existing largely.
