Note – Users can determine whether this point pair is involved in the
computation of either horizontal or vertical adjustment, or both.
7. Tap button in the lower right corner to save the point pair.
8. Continue the Step 2 to Step 7 to add all the point pairs.
9. If necessary, select the fit method for vertical adjustment from the
dropdown list next to Fit Method field.
Notes
The fit methods of horizontal and vertical adjustment are “TGO”
and “Fixed difference” respectively, by default.
There are four available fit methods for vertical adjustment: Fixed
difference, Plane fitting, Curved surface fitting and TGO.
1. The “Fixed difference” fit method is used when the measuring
surface is almost horizontal, and it requires at least 1 point pair
with elevation information to be involved in the computation.
