The use of UAV remote sensing for studying rockfalls and their impacts on forest [Elektronski vir] : doctoral dissertation = Uporaba daljinskega zaznavanja z brezpilotnimi letalniki za proučevanje skalnih podorov in njihovih vplivov na gozd : doktorska disertacijaŽabota, Barbara, 1992-In this research, we investigated the potential of using UAVs to acquire and produce photogrammetric and LiDAR products that can be used in analyses related to rockfall hazard and protection forest. ... First, we statistically evaluated the use of direct and indirect georeferencing through bundle block adjustment, a digital surface model, and orthomosaics. The results show that indirect georeferencing is more accurate, but direct georeferencing can be used on a representational scale with the potential to be used with only few ground control points (GCPs). Secondly, we compared field measurements of the dimensions and volumes of rock deposits with UAV photogrammetric and LiDAR point cloud measurements. The measurement results were further used as input parameters in a 3D rockfall model to test whether there are differences between the methods that could influence the planning of protection measures. There were no statistically significant differences between the measurement methods between the rock dimensions and volumes as well as for the modeling results of propagation probability and maximum rebound heights. However, large differences exist for modelled maximum kinetic energies. Finally, we used multiband UAV imagery and used it to calculate vegetation indices (VIs) to investigate whether it is possible to identify trees injured due to rockfall impacts, and differentiate between injury groups. The conclusions show that the identification of trees injured by rockfall (both conifer and deciduous tree species) was possible at study sites where rockfall injuries were at least one year old. It was not possible to distinguish between the injury groups in the injured trees, but there was a strong correlation between the VIs and the extent of the injury according to the basal area of the trees.Vrsta gradiva - disertacija ; neleposlovje za odrasleZaložništvo in izdelava - Ljubljana : [B.
