The digital terrain model (DTM) with removed pits is a precondition for hydrologic analysis.Two pit removal methods, the carving method and the filling method, are investigated in the paper for three different geomorphometric areas.The input data Beds - Bed Side Rails are digital elevation models (DEM) created by interpolation from photogrammetric surveying in the spatial resolution of 5x5 meters.A recommendation for the use of a more acceptable DEM creation method without pits, Verde Fabric Panel involving minimum geomorphometric changes, is given based on geomorphometric and statistical analyses.

The importance of selecting a correct algorithm is proven.
