In the two-peg of a dummy level, the following observation are taken. INSTRUMENT SET UP NEAR INSTRUMENT SET UP NEAR А В Rod Reading on A 0.921 0.367 Rod Reading on B 1.430 0.768 a. What is the difference in elevation between A and B? Answer: b. If the line of sight is not in adjustment, determine the correct rod reading on B with the instrument still set up at A. Answer:
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

The following tacheometric observations were made from station A to stations 1 and 2. The height of the instrument above the ground was 1.52 m. Take stadia interval factor and constant as 100 and 0, respectively. If the staff was inclined by 1° to the vertical, solve for the following:a. Error in horizontal distance if the staff is inclined towards theinstrument for the line A-1. b. Error in the vertical distance if the staff is inclined away from theinstrument for the line A-2. c. If the elevation of point 1 is 115.673 m, determine the correctelevation of point 2.
