select a method of traverse adjustment in the Total Station network.
The tab contains the following fields:
• Refraction Coefficient
- the current value of the coefficient of
refraction. This coefficient is used to correct the horizontal and
vertical distances (measured by Total Station) for refraction and
earth curvature. You can select "0", "0.14", "0.2" depending on
the measured distance and survey conditions.
• Traverse Adjustment Type
- the current type of traverse
adjustment in the Total Station network. Select the following
adjustment type:
- Least Squares - statistical method for providing a best fit for
survey point positions, and detecting and automatic rejection
of error measurements (blunders) by minimizing the sum of
the squares of measurement residuals.
- Compass Rule - this method assumes that the precision in
angles or directions is equivalent of the precision in
distances. This method works for closed traverses or
traverses between two fixed control points.
- Unadjusted closure - calculates the network coordinates
from the original station coordinates without estimating the
accuracy. If the network has duplicate measurements, only
one measurement will be used to compute the coordinates.

"Unadjusted closure" adjustment type is selected. If this check box is
selected, the application will:
