| Through more than 40 years'development, GIS (Geographic Information System) has made the huge progress, regardless of in the fundamental research or in the concrete project application, And utilized unceasingly in each professional fields along with the social application needs. In application scope, GIS serves for the department at early stage, and later for the government application, the local application, the national application, even global application. "The Digital Earth" also is brought up on the bases of three essential spatial information technologies' (GIS, GPS, RS) development and the integration. Computer technology development, As well as people's diligently exploration and research on relative technology and theory, All cause GIS develop by the unprecedented speed, WebGIS, COM GIS and Embedded GIS, Appeared one after another. Along with GIS apply on mobile terminal, smartphone and notebook, As well as LBS (Location Based Service) and the wireless network's vigorous development, Impelled GIS to develop to the mobile application, Mobile GIS is born, This causes anybody at anytime, anywhere to obtain the geographic information service become the reality, Moreover may foresee, Along with theory and technical further development, The Mobile GIS application's depth and the breadth can be more exciting.The paper's goal is to develop a Vehicles Navigation System based on Mobile GIS through the integration of GIS, GPS and Embedded Technology. This system has function of traditional Electronic Map display, inquiry and analysis, also realizes the vehicles real-time locating and the intelligent navigation function relying on the GPS localization technology.The paper introduces the intelligent Vehicles Navigation System's research and the development condition in the domestic and foreign, Elaborate the prospects for development of the Vehicles Navigation System, Analyzes Mobile GIS development condition, the essential technology and its application, Discusses the significance of developing and studying the Vehicles Navigation System based on Mobile GIS. Its research has the certain model value to the Vehicles Navigation System development in the theory and the method. The paper has designed the prototype system's overall structure, function module and so on. With the embedded development language Microsoft Embedded Visual C++, the author develops main function modules of the system, Researches the problems in the processing of implementation, Proposes the corresponding algorithm and solution. Finally Vehicles Navigation System which integrates the Electronic Map, GPS mobile localization, the route planning, the intelligent navigation functions——MobileMap has been realized.The paper mainly involves Embedded Development, GIS and GPS's integration, Stretches across Electronic Map design, mobile computation, localization, navigation technologies and so on, As well as Computer Science and Spatial Information Science. |
