7. Answer D Hight of instrument and height of target are required to derive the elevation difference.
8. Answer C
7. An elevation difference measurement by a total station is (a) is from the ground point...
5) The total station is setup at A and and a known backshot point is sighted to zero the horizontal angle. The known azimuth of the backshot is 63 03'18". Then the instrument is turned to point B with the following readings o Clockwise horizontal angle 55 37 '42" o Zenith angle 92°34 18" o Slope distance 435.09 ft o Height of the prism 6.00 ft Calculate the X, Y, and Z coordinates of point B. Assume the XY coordinates...
Coordinates for your occupied point: N: 30.0' E: 20.01 Elev: 68.14' Procedure: 1. Set up the total station over the occupied point. Level the instrument. 2. Measure the height of the instrument (point on the ground to the axis/centerline of scope) and the height of the prism pole (tip of the pole to the centerline of the prism). Measure the instrument height with a folding ruler and read the height of the pole from the scale on the pole. 3....
