Q I localized on 3 horizontal and vertical control points. One control point had a 0.58 foot height error. This error will of course be present in all of the positions located thereafter, since it was not detected until the job was done. Is there any way to remove this error in post-processing?

A Put the software into manual mode, manual entry, then go into Survey, Control Points. Select the control point you need to edit. Hit Edit Point, make his adjustment, hit ACCEPT, then ACCEPT again.
Go to Projection/Localization Setup and hit SOLVE, then ACCEPT. This should calc a new scale and rotation. Next go to Survey, Readjust Points. Select the points you want to adjust, in this case all of them. Check the horizontal and vertical boxes, then click on Geodetic to Plane button. All of the points will be adjusted.
