Creation of DEM by kriging method and evaluation of the results

Popis výsledku v původním jazyce

The generated DEM is used for deriving values of various morphometric variables of relief; however, their values differ according to the parameters of interpolation methods used. An improperly selected and set interpolation method results in the creationof a DEM of low quality, which then results in the derivation of erroneous values of geomorphometric parameters. Errors in derived parameters are usually much more evident than in the original DEMs. This is further enhanced by the properties (configuration) of the real relief ? plains, hilly lands, highlands and mountains (?relief? in a following text means the relief of the Earth's surface). It is evident that there is direct proportion between the relative relief seg-mentation and the examined inaccuracies ? in hilly areas the inaccuracies are smaller than in mountain-ous areas. Any error in the DEM then generates an error in the application results where relief is one of the factors. Particularly the process of testing the kriging m
