Tap . You will be warned that coordinates will

be changed. If you are sure you are ready to proceed, tap .

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.

Go to Readjust Points

from the Survey menu.

Select some points to readjust.

Tap the

Adjust Horizontal

and/or

Adjust Vertical

check boxes to

specify what to adjust.

Tap to open the second screen. You can choose

to or point coordinates.

Tap 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.
