Now, let's determine the move in latitude. The sketch shows the
retracement for the south half of the latitudinal line and the south
half of the calculated proportionate latitude.
This sketch shows the calculation of the move in latitude, South
As a check, calculate the move using the retracement data for the
north half mile. Notice that the bearing of the retraced line is
disregarded, since the record distance from the east will fix the
corner position and departure.
