【Abstract】 A method for interpolating digital depth model(DDM) considering uncertainty is proposed.The uncertainty of the soundings deriving from the different data sources is calculated,the interpolation model by using the uncertainty in weighting for the soundings is constructed,and the uncertainty of the interpolated depth node is estimated.Experimental results demonstrate that the proposed method has improved the quality of DDM and can estimate the uncertainty of the interpolated depth node. 更多还原
