The formula for calculating Tau is: Tau = (RES) / ?Res, where
(RES) - designates the residual calculated for the corresponding
component of the observation,
?Res - the RMS residual error.
Note: The value of Tau_critical depends on the number of
degrees of freedom and the selected level of confidence in the
Confidence Level field
.
• Adjust Dimension
- the current dimension for adjustment. You
can select either "1D", "2D", "3D", or "Auto". The default
dimension is "Auto".
– 1D: adjustment is performed ONLY in the vertical plane.
– 2D: adjustment is performed ONLY in the horizontal plane.
– 3D: adjustment is performed both in the vertical plane and
in the horizontal planes.
– AUTO: the adjustment will run in 1D, 2D or 3D mode for
each component depending on presence of control points.
• Adjustment Type
- the current adjustment type. You can select
either "Automatic Blunder Rejection" or "Interactive Blunder
Rejection". The default type is "Automatic Blunder Rejection".
If you select the "Automatic Blunder Rejection" type, the
application will automatically reject a blunder observation from
adjustment and calculate the final residuals for all adjusted points
without the blander component(s).
If you select the "Interactive Blunder Rejection" type, the
application will interrupt the adjustment process and show a list
of blunders. You can manually delete any blunder component
from the adjustment or continue the adjustment process.
and check boxes:
• Analyse Repeated Observations
- if this parameter is checked
(default setting), the application will perform the test of the
repeated observations:
- A successful test is where the difference between any two
repeated observations is less than the horizontal/vertical
