The generated DEM is used for deriving values of various morphometric characteristics of relief; however, their values differ according to the parameters of interpolation methods used. An improperly selected and set interpolation method results in the creation of a DEM of low quality, which then results in the derivation of erroneous values of geomorphometric parameters. This is further enhanced by characteristics (configuration) of the real relief - plains, hilly lands, highlands and mountainous. The article is focused on the evaluation of the digital elevation models created by various interpolation methods for different types of the relief using statistical analysis methods
