This graduate thesis presents methods and basic equations needed for practical determinations of non
verticality of the bell tower . Geodetic network was established in local coordinate system, measured
with classic terrestrial surveying methods, together with meteorological parameters, needed for
distance reduction calculation. Separately, horizontal and vertical procedures of least square
adjustment was calculated. Based on points with adjusted coordinates, the characteristic points of bell
tower was measured. Using the points located on the base stone and on the top of the bell tower, the
hight and lean angle was calculated. Theese results were compared with results of terrestrial laser
scanning thesis.
