In this diploma thesis, a kinematic GNSS field survey of selected mountain trails has been performed in order to evaluate the accuracy of their geolocation on maps and in other cartographic databases. A comparison between two different GNSS receivers has been made, namely one professional receiver (Javad Triumph-LSA) and one low-cost receiver (u-blox ZED-F9P), under different vegetation conditions on the mountain trails to Strešni vrh, Zasavska Sveta Gora and Kum. The main goal of this thesis is to determine how the vegetation affects the accuracy of determining the trajectory during movement. On the basis of the presented data it can be concluded that the low-cost u-blox ZED-F9P receiver performed better than the professional Javad Triumph-LSA receiver. It would be possible to do further research by investigating the performance of other affordable devices in terms of determining the movement of trajectories in difficult conditions. This would allow a better assessment of the quality of the data and serve as a basis for improving mountain trail databases.
