Summary:

Landslides in the geological aspect can be active for many years. There is
a need to keep monitoring stability of slope, especially if there are some buildings located on the landslide. Such monitoring can be done with the use of geodetic methods. In the article there are presented possible geodetic techniques which are used in practice and new one, not used up to now- ground radar interferometer technique. This technique allows for spatial measurement without the points stabi-lization on the landslide and gives the information about displacements values of the chosen area of measured landslide.
