Gross error elimination in DEM data by weight iteration with initial values

SUN Tong-he①,YAN Guo-qing②,ZHOU Qiang-bo③(①Mining Engineering Institute,Inner Mongolia University of Science and Technology,Baotou 014010,China;②Fifth Geology and Mineral Resources Institute in Inner Mongolia,Baotou 014010,China;③Research Institute No.230,Changsha 410083,China)  
This article merged the idea of robust estimation into the algorithm of detecting gross errors in DEM,in order to design the algorithm of resisting the model errors,especially gross errors.Robust Estimation contains the method of weight iteration with initial values.First,it was by linear programming method to calculate the residual errors of observed values.Second,based on the residual errors and parameters,the new weight value for each observation according to the weight function was figured up.Third,the residual errors of the observation was obtained through iterative calculation.Then the statistical methods were used to eliminate gross errors.Finally,the experiment showed that the studied method had strong robustness and good ability to detecting gross errors.
