I have had my property surveyed. One side I am going to fence. It is around 3/4 of a mile. Straight line E-W. The surveyor stuck some rebar in each of the corners. My problem is one corner is at the top of a hill and then (after two other hills) the other corner I am running the fence to is at the bottom of a hill. They are not in the same sight plane whatsoever. How would I go about plotting some point along this line? I realize one little mistake can realy compile itself after 3/4 mile of fencing.
