Pondelík, Marek: The Identification of Changes in Terrain Using Aerial Fotogrametry with the Use of a Remotely Piloted Aerial System. [Bachelor thesis] - Technical University in Zvolen, Faculty of Ecology and Environmental Studies, Department of Forest Management and Geodesy. Thesis supervisor Ing. Martin Mokroš, PhD. Qualification level: Bachelor (Bc.). Zvolen: Faculty of Ecology and Environmental Studies, 2018, 47 p.The main goal of our work was the identification of changes in terrain with remotely piloted aircraft systems. Manage images in the point clouds and the subsequent modelling of the digital model of the terrain of the area is conducted in the environment of the software Agisoft Photoscan Professional. Next, we made comparison of digital model of terrain from images made using the remotely piloted aircraft systems and the digital model of the terrain from airborne laser scanner. The comparison of the digital models of the relief was performed in the software ArcGis 10.2. which belongs to the geographical information systems. Then we evaluated the output data and set the degree of the shift in the slope. We also addressed the use of remotely piloted aircraft systems in the monitoring and identification of natural hazards, specifically landslides. We have used the method, that can be viewed as a low budget competitive alternative to airborne laser scanning.
