The following staff readings were taken in succession with a dumpy level. The instrument was shifted after 4th and 7th readings. Enter the data in a level field book and find the R.L. of all the points. The first reading was taken on a bench mark of R.L. 200.00 m. 1.75, 1.55, 1.85, 1.25, 1.35, 2.155, 1.525, 1.165, 1.085, 0.950 Apply the usual checks.

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.
