Digital terrain model (DTM) is represented by height points determined at the positions of a predetermined grid that characterize the height structure of the surface of interest.DTM of grid 30 m is made on the basis of aerial photogrammetric acquisition of resolution 10 cm, 20 cm and 40 cm from the epoch 2007-2010 and based on aerial photogrammetric acquisition of resolution 40 cm from the epoch 2011-2013 was updated.
DMT of grid 30 m is produced for the territory of the Republic of Serbia (excluding the territory of AP Kosovo and Metohija) based on data from aerial photogrammetric acquisition of resolution 10 cm, 20 cm and 40 cm from the epoch 2007-2010, and was updated based on aerial photogrammetric acquisition of resolution 40 cm from epoch 2011-2013.RMSE of heights is is 3 m and is calculated as difference between the values of the heights of the control points (717 points of the SREF network) measured on DTM and their values determined by independent measurement of higher accuracy in the field.Validity of the data set has been confirmed and is in accordance with the Rulebook on topographic survey and topographic-cartographic products.
