6. Review the Ground Coordinate parameters:
Reference Point Location, Ground Offsets, and
Ground Scale. When you are satisfied with the
setup, tap Finish.
7. If your projection record is a map projection zone,
the ground coordinate parameters will be added to
the zone record to create a zone based site. If you
are already using a site record, the parameters will
simply be applied. In both cases, the Adjust with
Projection wizard will open with the Results screen
to show the updated job file points. Tap Apply to
update the coordinate system and job file points.
Note: If your projection is a zone based site, then the
localization parameters will automatically be converted into the
corresponding ground coordinate values. You do not have to resolve
the localization.
8. If the conventional Survey Scale factor is not set to
1.0, you will be prompted to set it to 1.0. Using
Ground Coordinates, EDM distances correspond 1:1
to grid distances.
Switching from Ground To Grid
1. When Ground Coordinates are set, go to the Survey

3. Tap Accept to switch back to the mapping plane
grid coordinate system, and open the Adjust with

to set the coordinate system and update the job file points.
