A line of three-wire differential levels goes from benchmark Gloria o benchmark Carey. The length of the line was determined to be 199 m. The instrument had a stated compensator accuracy of +0.3". The instrument-rod combination had an estimated reading error of ±1 nm/km. The instrument is found to have an inclined collimation error of 1.0 mm/km, so the sight distances were kept to approximately 50 ± 5 m. If the difference in elevation observed is 15.601 m, what is the stimated error in the final elevation difference?

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.
