A Study On Comprehensive Application Model Of Mobile Spatial Information Based On GIS, Wireless Position, Mobile Telecommunication

GIS, Wireless position technology , wireless communication technology are developing rapidly , and profoundly in their application. The paper is trying not only to combine GIS, Wireless position technology, wireless communication technology and mobile terminal, but also to develop a comprehensive application system that possesses the functions of navigation, information enquiry and data collection etc.The paper analyzes firstly the technological background and characterristics of the key technology, with which model is concerned, and then the current situation and application expectation of Mobile Spatial Service. By analyzing the current relative application and theory, it points out the ideas that could be learned from them. On this basis, the auther puts forward the concept of Mobile Spatial Information Service. The symbolic characteristic of Mobile Spatial Information Service is removability, based on mobile devices.
