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.

In tacheometry survey, an intercept of 0.755m was recorded on a staff which was believed to vertical, and the vertical angle measured on the theodolite was +15º. Actually, the staff which was 4 metres long was 0.14m out of plumb bob and leaning backwards away from the instrument position. Assuming it was an anallatic instrument with a multiplying constant of 100, what would have been the error in the computed horizontal distance?

Fundamentals of Surveying All azimuths are measured from South. All angles must be written to the nearest minute only. All latitudes and departures must be written to two decimal places only. A series of perpendicular offsets were taken from a theodolite line to an irregularboundary. These offsets were at 3.20 m apart and were measured in the following order:1.5 2.5, 4.1, 4.3, 3.7, 2.8, 4.2, 5.3, and 1.4, meters.a) Determine the area using trapezoidal rule.b) Determine the area by Simpson’s one-third rule
