Digital terrain model (DTM) is represented by height points determined at the positions of a predetermined grid and structure lines that characterize the height structure of the surface of interest in which there are changes in the configuration of this surface.DTM of grid 5 m was made on the basis of aerial photogrammetric acquisition of resolution 10 cm from the epoch 2007-2010 and based on aerial photogrammetric acquisition of resolution 10 cm from the epoch 2011-2013 was updated.The issuance of digital terrain model is regulated by Law on Republic Administrative Taxes which regulates the amount of the fee for services provided by the Republic Geodetic Authority.
DMT of 5 m grid is made for 166 urban areas based on aerial photogrammetric acquisition of resolution of 10 cm from the epoch 2007-2010, and was updated for 87 urban areas based on aerial photogrammetric acquisition from the epoch 2011-2013.RMSE for height is 40 cm and is calculated as difference between values of heights of control points measured on DTM and their values determined by independent measurement of higher accuracy on the field.Validity of the data set has been confirmed and is in accordance with the Rulebook on topographic survey and topographic-cartographic products.
