Research And Design Of Military Electronic Map Based On GIS

Geographic information system (GIS) is a new integrated subject. It could combine all kinds of things with geographic positions and related views, and has powerful geographic data processing functions. The application of it is not only penetrated into every field, but also is used widely in modern military war.The paper aims at vehicles'practical demand in air defense system. Using ARM processor as kernel and making use of Vxworks operating system's hard real-time ability and high reliability, military electronic map system based on GIS is developed in the VxWorks's integrated development environment Tornado and multimedia package WindML. Firstly, it simply introduces the selection of ARM chips and the foundation of development environment of Tornado and debugging system. And then principally emphasized data mode of GIS, vector data structure, map display, data structure of GPS, information extraction, coordinate conversion and map matching technology.Finally, the experiment is performed upon the system, and it performs well. It's proved that the system can realize basic functions. It has some practical value.
