Abstract: Unmanned aerial vehicles are using often on research in deferent areas. Pasture research is one of them and include data brings and analysis for many of parameters that give an information about grassy, biomass, slope of terrain etc. This study present similar data analysis that bring with drone at area designed for cattle pasture in Rodopa Mountain in Bulgaria. Studied parameter is volume with grass vegetation using photogrammetry. Result obtained covered three-year study period, from 2021 to 2023 year. Two methods have been used to analyze the volume - Digital Surface Model (DSM) and Digital Terrain Model (DTM), comparing that which must be added or removed to level the surface with the surrounding land. The research and analysis of the results showed it requires additional researches to applicate of the presented method for determining the volume and amount of grass for low-height grazing on designated pastures.
