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.
