Abstract

In this paper the characteristics of one of the well known DTM interpolation method,the multisurface function method,are studied.As a result,a very simple cubic surface as kernel function of the multisurface function without any parameter has been found to be better than the hyperboloid one which was highly recommended by Hardy.This cubic surface is suitable for any type of terrain as shown in some computation examples.
