| Abstract: | Composition of geomagnetic map is useful for geomagnetic-inertia navigation system.to acquire high precision geomagnetic map,this paper have analysed modified shepard interpolation,and use it in composition of geomagnetic map.Besides,this paper have summarized the principle of composition of geomagnetic map.The results of the experiment validate that modified shepard interpolation can realize better result than inverse distance to a power interpolation and Kriging interpolation.Hence the paper give the conclusion that the algorithm is useful for composing high precision geomagnetic map. |
