surveying indirect leveling ₪ Verification measures

In fact the distance 56.92m was measured along the slope AB .

For verification, you also note the following, values :

₪ From the station at A, read the vertical angle at point B.

₪ From the station in B, read the vertical angle on A and N.

Repear the calculations from A znf check them from B. You Will calculate the akltitude of B on the way .
