A dumpy level with an internal focusing telescope was set up on the left bank of a river and the rod readings tabulated below were taken on a stadia rod held successively at the left and right water edges. If the stadia interval factor of the instrument is 100 and the stadia constant is 0.30m, determine the width of the river. Rod held at LWE: Upper Reading = 2.190 m & Lower Reading = 2.155 m Rod held at RWE: Upper Reading = 2.275 m & Lower Reading = 2.070 m

Point A has an elevation of 216.612 m above a vertical datum, and the point B is situated on the opposite sides of a busy twelve-lane highway (44.4 m width). For stability of both point locations are designed one meter away from each edge of the highway. From the measurement, the following results are obtained: Instrument setup at station 1 (A side of highway): Staff reading on A = 0.673 m Staff reading on B = 2.416 m Instrument setup at station 2 (B side of highway): Staff reading on B= 2.992 m Staff reading on A = 1.254 m Based on the description above, choose a proper measurement method used in surveying to realize the elevation at point B? Justify your answer.
Distance between the two points Pand Q was required to be determined from tacheometer fitted with an anallactic lens (k = 100, C = 0). With the instrument at P and staff at Q, the observations made were a vertical angle of + 8°43' and staff intercept of 1.805 m held vertical. At a later stage, it was found that constants of the tacheometer were 100.5 and 0.7. What would be the percentage error in the computed distance PQ? %3D
A level line from P to Q is carried out to and fro direct leveling, and the height difference of the forward measurement is 12.380 meters, and the height difference of the back measurement is 12.411 meters. It is also known that the closed difference limit value of the previous test and the back test K is 20 mm (K is the number of kilometers), the forward measuring level is 4.2 kilometers long, and the back measuring level is 3.5 kilometers long. Try to find the average elevation difference from P to Q, and whether the round-trip test results meet the regulations, and please explain your answer.
A tacheometer was placed at point P to estimate the horizontal distances PQ and PR. The corresponding stadia intercepts with the telescope kept horizontal, are 0.320 m and 0.210 m, respectively.
