The angular adjustment applied to each traverse leg is also displayed, along with unadjusted angles and adjusted angles
for each traverse leg. The adjusted coordinates are written to the coordinate file replacing the unadjusted coordinate
values.
Transit, Compass, Crandall Adjustments
These methods apply the selected rule to the traverse lines when calculating the coordinates. After adjusting the traverse
points, the sideshots can also be recalculated. The closure error is calculated as the difference between the specified
ending point and a reference point. The ending point is specified in the initial dialog.
You can change the ending point to correspond to the point in the traverse that closes back to the existing reference
point. In the current example, point 26 is the final shot, and is closing to an existing point, 10.
