Correct Base

This dialog allows to perform correction of the existing Base coordinates, or to assign new coordinates for the Base if it was installed at an imprecise position.

Warning: We advise you to experiment with the correction procedure before using it for work. This will allow you to understand whether the exported results and generated reports meet your requirements.

The Correct Base procedure can be performed without a connection to the Rover: for example, after the survey.

To perform the correction:

  1. Select a topo point (Topo Pt) and a point with known coordinates (Known Pt). Note that MAGNET Field does not allow base correction in case the Known Pt has local coordinates (offsets have 'N/A' values).
  2. Save changes. MAGNET Field recomputes the coordinates for all points measured using this Base in the current job.

The existing coordinates of the known point are not replaced by the coordinates of the measured point (Topo Pt); they are used for correcting or calculating the current (i.e., before correction) coordinates of the Base station. After base correction, the Raw Data dialog displays the base station coordinates as Ph. Center Coords (Corrected).

Note: The Correct Base procedure can be repeated. Old corrections will be replaced with new corrections, and all dependent coordinates will be updated in the project. Correct Base dialog allows you to return to previous corrections at any moment.
