Abstract

It is known that digital elevation models (DEMs) can vary in quality depending on spatial sampling schemes. Three DEMs were created by Kriging interpolation from sampling points which come from different sampling schemes. Using a test setup, three different sampling schemes and different semivariogram models (Circular, Spherical, Tetraspherical, Pentaspherical, Exponential, Gaussian, Rational Quadratic, Hole Effect, K-bessel, J-bessel, and Stable) are compared. The results show uniform random sampling scheme to better than the other candidates.
