An accurate geodetic network has been established at the Hydroelectric Power Station (HPS) Moste in order to monitor any movements of the barrier. A part of HPS Moste is also stone wall, which is being studied in the graduation paper. It was marked with reflective tape targets to track its movement in the past. However, since they were damaged because of the impact of the environment, new points had to be assigned. Our primary task was to establish a mathematical connection between new and old points so as to have complete data and to be able to track any changes in time. Furthermore, we have decided to do an evaluation of reflective stickers and their use as described above. The graduation paper conclusions are 3D coordinates of old and new geodetic points as well as their standard deviation and the deviation of separate groups of correlated points.
