A theodolite is set up over point A. The vertical distance from point A to the center of the theodolite is 4.66 feet. Point B which is 900.00 feet (slope distance) away from the center of the theodolite is observed at a zenith angle of 84°4530". What is the elevation of B to...

A level has been found to be out of adjustment. When a two-peg test and adjustment were made, two stakes (A and B) were set 215 ft apart. When the instrument was set up midway between A and B, the rod readings were 4.26 on A and 5.15 on B. When the instrument was set up very close to A, the rod readings were 6.02 on A and 6.79 on B. With the instrument remaining near A, the crosshairs should...

7. An elevation difference measurement by a total station is (a) is from the ground point at the total station to the ground point at the prism computed from only slope distance and zenith angle (b) requires the horizontal circle to compute the elevation difference (c) requires sighting a known elevation on a backsight (d) usually requires height of instrument and height of target to be correctly derived 8. A horizontal angle at 2 from 1 to 3 is 65-08-10,...
