This master's thesis examines the displacement analysis of a geodetic network located at the Ljubljana car fair, which lies on a former landfill in the Ljubljana Marsh. The geodetic network, consisting of eight points, was measured in two epochs, in 2021 and 2024. A combination of classical geodetic measurements and static GNSS observations was used, enabling vertical, horizontal, and spatial (3D) network adjustments. Measurement processing included distance reduction, calculation of height differences, and GNSS data processing using Leica Infinity software. For all types of adjustments, point coordinates and their corresponding accuracies were computed, and the results were used for Hannover deformation analysis and displacement assessment. Displacement analysis was carried out on two levels: using combined classical and GNSS data, and using only static GNSS observations. The results of the Hannover analysis and displacement evaluation were comparable and showed that only point T5 remained stable in the 3D network. The most significant were the vertical displacements determined by GNSS, reaching between 3 and 4 centimeters at certain points. The combined method indicated mainly local deformations.
