Convergence Calculator
1. Go to Projection Calculator from the Survey menu.
2. Choose a point on the mapping plane for convergence
computation in the Select Point control. Tap
6ROYH 5RWDWLRQ!.
3. The convergence and rotation are calculated. The convergence is
displayed in the Geodetic N to Grid N box. The rotation is
displayed in the Grid N to Geodetic N box.
4. Tap
$FFHSW when you are done. Both numbers are saved in the
Past Results list so you can use them in other calculations.
Readjust Points
The Readjust Points screen is used to perform transformations from
geodetic to plane coordinates and vice versa.
Note: If you resolve a localization adjustment, the plane coordinate
of all of the geodetic point records is automatically updated. It is not
necessary to use this screen to update job file coordinates with Survey
Pro.
Geodetic to Plane
This function recomputes the plane coordinates of the selected points
using the geodetic 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.
