Note: If you select a point from the job’s control file, you will be
prompted to make a local copy of the point. Control point collection
will add a geodetic coordinate to the point record and points in the
job’s control file cannot be modified.
Note: If Store GPS Raw Data on the Measure Mode card of the Job,
Settings screen is set to EP + Rx Raw (or + OBN for Ashtech users),
when you begin a point occupation the control point name is checked
as a valid site ID for the receiver. If it is not a valid site ID, we will
use a modified point name in the receiver’s internal file and make a
note of the modified name in the job’s .RAW file. The point name in
Survey Pro is not changed.
