The residuals of the transformation
are displayed. This is the difference
between the transformed WGS84
coordinates and the original
coordinates in the local system.
Values that are marked with a star
indicate where the highest residuals
lie.
Use INFO (F5) to view the height
residuals.
Use RESLT (F3) to view the
transformation calculation result (the
calculated transformation
parameters). The information given
will differ with the type of
transformation performed.
Classical Transformation Results
The Name and Trans formation
Model (Trans model) used are
displayed.
Then the calculated translation
parameters are displayed.
Shift dX, dY, dZ - Shift along X, Y
and Z axes.
Rotation X, Y, Z - Rotations about
X, Y and Z axes.
Scale - Scale factor between the
two datums.
1-STEP/ 2-STEP Transformation
Results
The transformation is split into a 2D
Helmert transformation for position
and a Height Interpolation.
For a 1-Step transformation the
center of gravity of the points on the
WGS84 Datum is calculated. A
temporary central meridian is then
constructed through this center of
gravity and a Transverse Mercator
projection applied.
