Description
Access
Traverse
☞
Optionally the traverse can be adjusted.
This option is used for determining the closure of a closed loop traverse, con-
sisting of a single control point with an arbitrary backsight azimuth. This func-
tion allows completion of a traverse without having to reoccupy the initial
setup to measure a closing angle. The positional closure is calculated by com-
paring the control position of the initial setup to the measured position of the
final foresight. The angular closure is calculated by comparing the set azimuth
of the initial backsight to the azimuth of the final measured leg.

1.
The first setup is on P1 in the diagram shown.
Begin the traverse, moving in the direction P1, P2...P6.
2.
The last setup point is on P6 in the diagram shown.
When on the last setup point, measure a backsight.

Measure all the sets to the closing point as per a standard traverse.

Creating a Control Point from Backsight by Azimuth
If a traverse is to be established on existing control points, two control points
must be defined to start the traverse. If the traverse absolute position is arbi-
trary, it can be convenient to define the control in the field with arbitrary val-
ues. This functionality is an option to turn the averaged position value into a
control point when a backsight by azimuth is collected.
At the beginning of a traverse, when all the measurements are completed
to the backsight: On the Point Results panel, select Page to reach the
Bcksght page. Fn Design.
OR
The first setup is on P1, and
an assumed direction to back-
P5
sight P6. Upon closing the
P4
traverse, with the last setup
over P6, the closing point is
P1. In this case, the only
point that is considered as a
P3
control is P1.
