Effects of interpolation errors on the analysis of DEMs

Auteur(s) et Affiliation(s)



Description :
A suite of methods to interpolate a digital elevation model from a ground survey was evaluated with respect to precision and ability to maintain the shape of the original height data. The best interpolation method for this study area was found to be a spline interpolation, which is somewhat contradictory to findings in the literature. The A. also investigates the effect of errors in height, which may be attributed to interpolation, on a sample of terrain analysis operations in order to see to what extent the interpolation might influence the derived data from DEMs.
