Traverse Adjust
The Traverse Adjust wizard will perform an angle adjustment, a
compass rule adjustment, or both.
Angle Adjust
The Angle Adjust routine will compute the angular error
in a closed traverse from a known closing angle. It will
then distribute that error equally among all of the
internal angles so that the resulting sum of the angles
will equal (N-2)·180° because the sum of the internal
angles of any closed polygon can be computed using this
formula, where N is the number of sides of the polygon.
After performing an angle adjustment, all of the points
except for the first two points will be adjusted. (The
azimuth of the first leg will remain constant.)
The closing angle provided is used to compute the
angular error. It is the angle as you occupy the closing
point, aim toward the second point and turn an angle-
right to the second-to-the-last traverse point (see
illustration).
Note: An angle adjustment does not always adjust the closing
point to a location that is closer to the starting point.
