4. Tap *HRGHWLF WR 3ODQH!. You will be warned that coordinates will
be changed. If you are sure you are ready to proceed, tap 2..
5. The final page displays the results. The Results box displays the
number of points adjusted. If some points were not adjusted, a
list of these points and an explanation why they were not
adjusted is displayed.
Reasons Points are Not Adjusted
•
Setup Group Not Compatible: If you selected a point that does
not belong to the current set up group, then it is not adjusted. If
the set up groups do not match, we cannot be sure the geodetic
coordinates are accurate with respect to the current projection
solution.
•
Geodetic Coordinates Not Valid: If you selected a point without a
geodetic coordinate, it is not adjusted. Without geodetic
coordinates, we cannot re-calculate a new plane position.
•
Control Point: If you have selected a control point it is not
adjusted. Control point locations cannot be modified.
Plane to Geodetic
This function checks or re-computes geodetic coordinates of the
selected points using the plane coordinates and the latest projection
solution.
1. Go to Readjust Points from the Survey menu.
2. Select some points to readjust.
3. Tap the Adjust Horizontal and/or Adjust Vertical check boxes to
specify what to adjust.
4. Tap
3ODQH WR *HRGHWLF! to open the second screen. You can choose
to &KHFN! or 5HFDOFXODWH! point coordinates.
5. Tap &KHFN! if you want to compare the plane coordinates to the
geodetic coordinates. The projection will be applied to the GPS
coordinate and the result will be compared to the plane
coordinate. This operation does not change coordinate records.
