| With the rapid development of science and technology, the global positioning system(GPS), geographical information system(GIS) and wireless communication technologies become maturer and more integrated, some GPS/GIS navigation service industries come out. In this situation, the integrative research on GPS and GIS Navigation Electronic Map becomes a focus of many scientific researchers and companies. Researches on the integrated application of GPS and GIS in navigation electronic map become more extensive and deeper. Recently, many home and abroad scholars make a mass of studies, in the field of the in-vehicle location and navigation system and handset's navigation. Using integrated navigation electronic map, users can obtain comprehensive and abundant geographic information such as traffic route, road state and so on. In abroad, the application and research in the area of GPS/GIS navigation service industries are relative mature. However, because of technology, economy, and policy, our research in this field is still at its elementary stage, the potential market is very enormous, and it is very significant to study the research.On the base of many refrerence books and papers, integrated the application of in-vehicle location and navigation system, this thesis begins with the development of GPS and GIS Navigation Electronic Map and introduces the role and significance. Secondly, it describes GPS data receiving from GPS receiver to PC and data processing, including explanation of NMEA0183 data format, data decoding and coordinate transform. Thirdly, how to design and make navigation electronic map based on MapX is discussed. Fourthly, it also discusses the shortest path problem, introducing in detail shortest path algorithm and how to apply it in navigation electronic map. And then, the personal terminal system of GPS navigation electronic map is designed and programed by Visual C++.Finally, this paper makes a summary and points out the problems and something to do in future.
