Research on DEM Construction Method of Interpolation

Abstract:

DEM construction quality directly affects a variety of applications based on DEM and terrain analysis. Giving the error in measured data, interpolation methods affect the quality of DEM. Therefore, for a certain district, choosing a better interpolation method is very important. In this paper, we constructed new DEM by three interpolation methods (inverse distance weight, spline, Kriging) on the real DEM data of loess tableland. By comparing this new DEM with the original DEM and analyzing this new DEM, we can get a better choice of interpolation for DEM construction and terrain analysis for a certain district.
