The aim of the diploma thesis is to compare ground photogrammetry and manual measurement of soil damage after mechanized wood concentration. The thesis is theoretical-research. The theoretical part describes the soil conditions in the Slovak Republic and mining and transportation technologies used in the Slovak Republic in the concentration of wood. It characterizes soil damage and deals with methods of modern and traditional methods of soil damage assessment. The research was carried out in LS Turčianske Teplice, LO Sklené, where mechanized concentration of wood after calamity caused by wood-destroying insects was carried out. For the research, 6 experimental plots were selected on which timber was harvested using a John Deere 770D harvester. We determined the depth of the tracks using the method of transverse profiles and the method of ground photogrammetry. When the harvester passes, damage to the soil occurs already during the first pass through the terrain. On the experimental plots examined by us, the average depth of the tracks ranged from 4.75 to 8.49 cm, which fell into damage class A and B, ie “almost no” and “small and medium” soil disturbance. There is a statistically significant difference in the volume of damaged soil between soil damage assessed by the ground photogrammetry method and soil damage assessed by the transverse profile method, which was confirmed by correlation analysis and Student's t-test. Correlation analysis also confirmed that there is a linear relationship between the soil damage assessed by the cross-section method and the longitudinal slope. The linear relationship between soil damage measured by ground photogrammetry and longitudinal slope was also confirmed.
