6.4 Height measurement

6.4.1 Height measurement
The tool can be used to measure heights or differences in height.
Height measurements are made using the trigonometrical height measurement principle and are calculated accordingly.
The height measurements take the vertical angleand the slope distance in conjunction with the instrument height
and thereflector height into account.
dH = COS(VA)*SD+HI−HR+(corr)
In order to calculate the absolute height of the target point (point on the ground), the station height (Stat H) is added
to the delta height.
H = Stat H + dH
