Errors in surveying

An error in surveying is defined as the difference between two or more values of an identical quantity. However, the estimates are never accurate and there will always be a degree of variability regardless of the research tool or method used. These differences are known as errors that need to be reduced or eliminated to maintain certain levels of accuracy. Even if you carefully follow the prescribed test procedures, the considerations may contain errors.

Q:The following consecutive readings were taken with a leveling instrument at intervals of 25 m. (3.375, 2.730, 1.615, 4.450, 3.835, 3.070, 2.835, 1.985, 1.435, 2.630, 3.255, and 4.630 m). The instrument was shifted after the fourth and eighth readings. The last reading was taken on a B.M. of RL 111.200 m. Find the RLs of all the points (Height of instrument method).

What is the loop misclosure? b. What is the corrected elevation of point B using an adjustment by setups? 12
To test its line of sight adjustment, a level is set up near C (elev. 193.436 m) and then near D. Rod readings listed in the order taken are C = 1.315 m, D = 0.848 m, D = 1.296 m, and C = 1.767 m. Compute the elevation of D, and the reading required on C to adjust the instrument.
The height of instrument is 75.05m and the foresight on a turning point is 1.83m. After the instrument has been moved forward and set-up in a new position, the backsight on the turning point is 2.92m. The rod readings on station 1, station 2 and station 3 are 1.59m 1.92m and 2.29m respectively. a.Compute the new height of instrument. b.
