Determining dip is pretty simple if I am standing right at the water's edge. But if I am standing on a hill or cliff, what is my best way to determine dip?
Is it feasible to relate my height above "mean sea level" from a topographic map to the state of the tide to come up with my actual height above the water's surface?
