Survey were carried out on natural ground, along the midline of a road project. The following staff readings are recorded (1.150, 1.550, 2.350, 2.650, 1.800, 2.750,1.600, and 2.550m). Note that the instrument was moved after thé fifth reading which its elevation was 30m. The formation level of the is Im higher than the natural ground level frem the start to end station. Determine elevation of the points and find depth of cut and fill at all stations then draw the profile of the project. Knowing that: T-The slope of the road is uniform 2- Distance between stations is 100m

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.
