s dependment on the GIS and demand for the GIS are levels rising,But traditional GIS can not meet the needs of human production and life.Today, computer technology, wireless communication technologies continue to mature,these developments of technology brings opportunity for mobile GIS.The hot spot of the GIS research in the future is how to combine mobile GIS with advanced computer technology, communication technology,it is also an important and better development for mobile GIS. This paper studied the characteristics of mobile GIS and its architecture,and from the technical aspects of information services on mobile GIS system design its key technology,For example, map matching, map data, and analysis of spatial organization, the mobile terminal technologies such as wireless location technology.On this basis, using C # language support in Himap control platform for the development of mobile GIS based PDA system,this system includes map browsing, graphics editing, and ranging, query and other functions, and ultimately to the campus map as an example of system testing and validation. This article is designed for mobile GIS system integration of advanced personal computer technology PDA, mobile communication technology.It is the expansion of mobile GIS applications.Advantages of this system is break the traditional mechanism for location-based services, geographic information from the interaction of time and space constraints, anytime, anywhere to provide convenient, fast and reliable information inquiries.
