Working with a Scale Factor
Once a mapping plane scale factor is configured for a job,
the scaling affects most of the other screens and
routines. For example, when viewing the coordinates for
a point, where you would normally only see the ground
coordinates, you will now see both ground and grid
northing and easting coordinates.
On screens that contain a field where a distance is
measured from an instrument (manual input of shot
data, GPS offset shot data, stakeout tape
measurements), it is assumed these distances are on the
ground and therefore the scale factor will be applied
automatically before calculating horizontal distances in
the job.
On screens that contain a field where a horizontal distance is always
keyed-in manually, it is assumed that the distance you
enter will be a grid distance and no scale factor is
applied. If you need to enter a ground distance in one of
these fields, you can scale the distance entered from
ground to grid using the Apply Scale Factor option from
the associated power button before solving.
Once you choose Apply Scale Factor from the drop-down
list, what happens next depends on how your scale factor
is configured. If you are using a single combined scale
factor, the number you input in the settings is applied
and the new distance is inserted in the edit field without
any additional steps.
