Import Control

This option will read control points from a control points file.
The points will then be matched by their name and updated.
When a match is found, new coordinates are copied from the Import control file into the job.

A control point file can have all the control points for a locality that may cover a number of parcel ‘areas’. The file may be the output from a geodetic adjustment or from a GPS system.
