Concept:In a closed traverse survey, the surveyor returns to the starting point after taking measurements.
When the computed endpoint does not match the original starting point, the resulting gap is called the
error of closure.
Explanation:A closed traverse begins and ends at the same point.
If all angular and distance measurements were perfect, the final plotted point would coincide with the starting point.
Any failure of the endpoint to fall exactly on the point of origin indicates a cumulative measurement mistake.
This mistake is known as the
error of closure.
It is only detected when the field measurements are plotted or computed in the office.
Answer:C. Error of closure
