Which of the following statement is correct?
I. Check line is a line that is measured after the survey is completed to ensure the accuracy of the survey
II. Base line is the long survey line that runs through the middle of the area to be surveyed
Statement I (Correct): A check line (also known as a proof line) is a line run in the field
specifically to verify the accuracy of the triangular framework. It is measured after the
framework lines are surveyed to ensure that the fieldwork contains no significant errors.
Statement II (Correct): The base line is the most important and longest survey line in chain
surveying. It generally runs right through the center or middle of the area to be surveyed,
serving as the main reference line from which all other triangles and measurements are built.
