Abstract

Thesis deals with comparison of various software for unmanned air vehicles (UAV) data processing with focus on digital terrain model acquisition. In the first part are described the basic principles of data acquisition using UAV, are being described together with characteristics of testing areas and selection of software used for processing of this data. Comparison of software was realized by several ways In the theoretical part their functionality potential and licensing policywas examined. The next part was based on practical tests, where processing time, positional accuracy and overal software functionalitywas evaluated. The final step was the comparison of created digital terrain models with the official source of elevation data for the Czech republic and with own GNSS measurement. Four softwares were selected of which Agisoft PhotoScan and Pix4Dmapper achieved the best results.
