Abstract: According to the actual requirements,the advantage of total geomagnetic intensity gradient amplitude used as matching feature is analyzed in four aspects.The reference map of selected area is produced with the total geomagnetic intensity gradient amplitude matching feature.The matching feature parameter of the map is extracted and analyzed.The results indicates that the reference map produced is more advanced with abundant feature,large variation range and high matching probability than that produced with the total magnetism intensity as matching feature.
