Abstract: Digital model of the relief (DMR) is an important part of geographic information system (GIS). For the creation of DMR have been used spatial data, which are achieved by geodetic measurement in the field, from secondary sources (analogue maps) and photogrammetric processing of aerial photographs. Very important is to know the vertical accuracy of DMR. The article describes evaluation of the vertical accuracy of the three DMR from the agricultural farm Kočín (creating from aerial photographs at scales 1:27,000, 1:8,000) and ZM 10, which is based on the real slope of relief.

Keywords: digital model of relief, geographic information system, digital photogrammetry, vertical accuracy, slope of relief
