This diploma thesis points out the consequences caused by the motion of forest machinery in terrain with or without the use of grip tire chains. We are examining mainly the effect on the ground or soil and the plants left or new. For monitoring the consequences we use the modern system of digitally dynamic surface photogrammetry which allows us to quantify the damage and figures such as the depth of the trace, damaged area, capacity of soil... Today’s methods and techniques of photogrammetry allow us to get quality and quick data. An important part of the thesis is the comparison of the effect of forest machinery with and without the use of grip tire chains measured with standard instruments, penetrometer but also obtained from the 3D models created with digital photogrammetry. We describe the negative impact of these additional components but also of the tires themselves. The aim of this thesis is to depict the effectiveness and adequateness of the use of grip tire chains in the process of wood harvesting and transporting in every circumstance. The thesis also informs about the effect of the forest machinery on erosion of the soil and the amount of the soil carried away after each passage. The readers of the thesis can also learn about the results obtained from digital photogrammetry, which move the valuation of the damage caused to the soil forward to a more modern level.
