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.
