Optimal digital terrain model for erosion analysis
 Středová, Kamila ; Brychta, Jiří (advisor) ; Rejha, Vít (referee)
The thesis deals with the question of using available sources of elevation data for the evaluation of topographic factor in estimating the amount of water erosion in the area. Work compares the results with consideration to the origin of the data, the accuracy and resolution of the digital terrain model, which is interpolated from the source data. The calculation of topographic factor in ArcGIS will be confronted with the results of the Universal Soil Loss Equation (USLE). The frequency of compliance will tell us which data source and digital terrain model resolution is the most suitable for determining the topographic factor.

Photogrammetry using UAV and non-metric photocamera
 Filín, Slavomír ; Brychta, Jiří (advisor) ; Rejha, Vít (referee)
This thesis deals with the use of unmanned airborne vehicles especially in environmental sectors. Gradually they describe the different types and characteristics of aircraft. The introduction explains the historical development and the legislation applicable to the management of unmanned airborne vehicle. Another part deals with processing of the results acquired with the help of UAVs. It is explained by the physical principle of data collection. The following describes the different types of data that can be obtained by placing different sensors and cameras for UAV support. This is a multispectral, hyperspectral, thermal imaging and lidar sensors. It explains the process of evaluating the measurement data in the GIS environment. Work also addresses the evaluation of the images taken by UAV with the help of a semi automated software. The paper presents examples of the world's most pervasive software. Attention was also placed on the use of individual outputs. The last section provides examples of the use of UAVs or software on concrete examples, where the UAV resources necessary tool for the project implementation.
