Scale Adjustment

The Scale routine will adjust the coordinates of selected points by a
specified scale factor relative to a base point. This is useful to repair
data that was collected where an incorrect scale factor was applied.

2.

Use the

7DS 3RLQWV« or 7R)URP« button to specify

the points that you want to adjust.

3.

Enter the name of the base point in the

Base Point

field.

4.

Specify the scale factor to apply in the

Scale Factor

field.

5.

If you also want to adjust the elevations of the
selected points, check the

checkbox.

6.

Tap

6ROYH. The coordinates for the selected points

will be adjusted.

Note: If you choose to also scale elevations, the scale factor will be
applied to the difference in elevation between the base point and each
selected point. For example, if the base point elevation was 100 and
the elevation for a selected point was 150, applying a scale factor of
0.5 would result in an elevation of 125 for the selected point.
