Abstract
This paper presents the evaluation of three remote sensing methods used in geomorphological mapping of cliff coasts. The basic parameters of point clouds obtained in the process of airborne laser scanning (ALS), terrestrial laser scanning (TLS) and digital processing of photos obtained with UAV (Structure from Motion – UAV-SfM) were analysed. The obtained results allowed to state that the models with the highest resolution and accuracy can be obtained using the TLS and UAV-SfM methods. These two techniques provide the greatest possibilities in detailed relief analyses and estimation of the sediment budget in small research sites. Images of ALS are less accurate, but for studies carried out in larger areas they seem to be the most optimal solution.
