One SUAV earth station three-dimensional navigation map realization method

The invention discloses a kind of SUAV earth station three-dimensional navigation Map Design method, comprise based on Google? Earth? the map datum of API obtains, geographical coordinate is changed and navigation feature implementation method. Do you use Google? earth? API has realized the network map data of flight range has been saved in local two-dimensional array; Use three-dimensional drawing interface that map datum is plotted in to navigation map district of earth station and form three-dimensional map; By locally inquiring about unmanned plane during flying destination position and draw in diagram data, realize three-dimensional map navigation feature in three-dimensional map. By the method, can provide three-dimensional navigation map cheaply for SUAV earth station, improve map intuitive display and the flight safety of unmanned plane under complex terrain condition.
