Using a tacheometer, the following readings were obtained:
Data:
Zenith angle (z): 45°
Reading on stadimetric wires:
High wire: 1.485 m
Medium yarn: 1,000 m
Low wire:0.948 m
Instrument height: 1.50m
Height of observed point: 0 m
Calculate the horizontal distance from the observed point and the height of the cliff in relation to the instrument position.
∆d = 100. (A-B). cos²z
∆h = Dx tan(z)+ (hm+hi-hv)
- Give preference to make the resolution editable, handwriting hinders understanding.
