In this thesis, we tested an electronic total station Leica Nova MS50 MultiStation, which includes
technology of terrestrial laser scanning. There have been two independent measuring the overflow
wall of the small hydro power plant Melje which allowed us to assess the deformation of overflow
wall. Because the instrument enables the direct georeferencing, we have easily integrated point clouds
from first and second epoch into the project coordinate system. Comparision of point clouds from first
and second epoch was treated with open source programs Cloud Compare and MeshLab.
