Convergence Calculator

Go to Projection Calculator from the Survey menu.

Choose a point on the mapping plane for convergence

computation in the

Select Point

control. Tap .

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.

Tap 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.

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.
