Abstract

The aim of this diploma thesis was accuracy verification of elevation data included in ZABAGED® database, product Digital terrain model 5th generation and its stated accuracy on exposed terrain. This thesis describes basic information about digital terrain models, their usage, data sources and steps during creation of digital terrain model. It also describes information about ZABAGED® database, its development and division into products. Accuracy verification was in form of geodetic survey on selected location, making digital terrain model from measured data and data of DMR 5G product and their comparison. The result of the thesis was the evaluation of deviations between measured data and data of DMR 5G product on different types of terrain.
