ABSTRACT:
A navigational plotter includes a light-transmissive LCD graphical display which serves as a window-like element in relation to a map placed underneath it. The map is calibrated to the plotter by moving a calibration cursor on the display to two known points diagonally displaced on the map, by manually entering the latitude and longitude of these known positions and by commanding the device to associate each point with its respective longitude and latitude. Navigational positions and navigational paths are then related to these points and displayed at the appropriate locations on the graphical display, where they appear over the appropriate locations on the underlying map.
