Summary:

The monitoring of the terrain subdued to landslide processes is necessary for the safety of the objects within that area. This article presents the description and the results of the measurement studies to optimise surveying technologies of the observations of ground deformations in the area subdued to landslide processes with the use of rosettes. The measurements were carried out with the use of three instruments (total stations: TCA 2003, TCR 303, TC 407) on the test field. Based on the carried out studies, the optimal way and instruments were selected for the potential use in the observations on the actual area subdued to the landslide processes.
