Analysis of terrain skeleton lines in rocky terrain: comparison of information based on ZM 10 and DMR 5G

G. Kyncl 2022 Analysis of terrain skeleton lines in rocky terrain: comparison of information based on ZM 10 and DMR 5G Abstract This thesis deals with analysis of terrain skeleton lines in rocky terrain based on cartographic representations of rock formations in Czech state map series. The main aim of the work is to determine how much the representations of rock formations correspond to reality. In the theoretical part the method of rock drawing used in the Czech state map series is described. Then the procedure which was used to derive the terrain skeleton lines from rock formations representations is described. This procedure was for the purpose mentioned above used in author's bachelor thesis. In the next chapter selected methods used for the detection of terrain skeleton lines in digital terrain models are briefly described. Then one of the described methods is chosen and used with modifications in the practical part of this paper. The next section deals with selected methods from the field of digital image processing and computational geometry. The last part is focused on the description of selected methods used to determine the degree of correspondence of linear objects. In the beginning of the practical part the data used in this work are described. The main part of the thesis is focused on..
