Abstract：The basic progress of digital depth modeling for navigation is analyzed,and the common interpolation methods ap-plied in the DDMs for navigation are introduced. Then the effects of the interpolation methods are analyzed in the DDMs for naviga-tion from the aspect of the assuring rate,representativeness and efficiency. The experimental results demonstrate:1)the assuring rate of DDMs constructed with the shoalest interpolation methods is the highest,the represetativeness of the DDMs constructed by the linear interpolation methods is the highest,and the efficiency of the both two methods above are the highest in the common meth-ods. 2)the surface of the depth models constructed with the shoalest interpolation method is discontinuous while that with other com-mon methods(e.g. the linear interpolation methods)is not. As such,the linear interpolation method is confirmed to be the optimal interpolation method in the DDMs for navigation.
