Experienced surveyors can attain accuracies of up to at least one aspect in ten,000 (1 centimeter mistake for every a hundred meters length). Sources of error incorporate flaws while in the tape by itself, which include kinks; versions in tape length as a result of extremes in temperature; and human mistakes which include inconsistent pull, permitting the tape to stray in the horizontal airplane, and incorrect readings.
