The present invention relates to a method for checking a numerical error in a numerical map through a precise analysis of ground control point information. The method is used to restore an important ground structure or a specific terrain which is edited to be deleted by being designated as a restricted area in the numerical map, to check the numerical error in a numerical map image based on the ground control points of the numerical map in order to update the numerical map precisely in accordance with restoration. The method includes a numerical map image output step of enabling an output module (11) to output the numerical map image having the restricted area deleted. The method also includes: an error correction step; a restricted area checking step; an adjacent area checking step; a restoration range checking step; a set restoration target determining step; a terrain relief checking step; a restoration step; a template searching step; a template editing step; and a template replacement step. |
