a) In the process of taking a rod reading, one can eliminate parallax mathematically. Parallax is basically a systematic error. True False b) The page check in the field notes is a quality control measure to determine if the user satisfied 1st order class I leveling. True False C) The upper cross hair reading was 8.00 ft. The lower cross hair reading was 6.00 ft. The stadia constant was 100. The horizontal distance from the center of the level to the face of the level rod = 200.0 ft. True False
