Deformation monitoring of slope instability and its surroundings supplies important
information on the behavior of the slope in that it evaluates whether potential collapse may
occur. Monitoring results may also be used in verifying design geotechnical parameters of
slopes such as in mines and aid in the calculation of soil mass volume. The development of
digital Photogrammetry allows calculation of high accuracy three-dimensional coordinates
for points on and around the slopes. A main advantage is that no physical contact with the …
