Prepare a table of the above readings (as you did in the class and lab) and calculate the heights of all the stations (represented by capital letters). 2. Check the accuracy of your own calculations. 3. What was the leveling error of the job. 4. A foresight was taken from X to the creek and the reading was 13.54ft. Likewise a foresight was taken from Y to the bottom of the cliff and the reading was 13.77 ft. Calculate the depth of the creek and the height of the cliff. - E E Oao-
