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.

1. Tap Adjust , Scale from the Main Menu.

2. Use the Tap Points… or To/From… 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 Include Elevation in

Adjustment checkbox.

6. Tap Solve. 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.
