1. one kind shows the method that en-route visible terrain shows to aircraft, comprising:

  • Use geographic position and this locational height above sea level to represent each pixel of gound-mapping, each pixel also uses in color value and the gray-scale value at least one further to be represented;

    Receive minimum elevation value;

    The color of pixel value that to be represented by the altitude value littler than the minimum elevation value that receives and at least one in the gray-scale value are set at unified value;

    WithShow that this en-route visible terrain shows, be shown with unified value thereby expression comprises the pixel less than the landform of the altitude value of minimum elevation value, therefore the non-crowded landform that shows, to dominate the territory, navigating area easier to be readable.
