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.

Note: Base correction cannot be performed if the Known Point with the existing Base coordinates has local coordinates (offsets have 'N/A' values).

The Base correction can be applied in two ways: 1 - to horizontal and vertical coordinates of the existing Base or 2 - to vertical coordinate only.

  1. To perform the correction of horizontal and vertical coordinates of the existing Base:


  2. To perform the correction of vertical coordinate of the existing Base:

Click to recompute 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); the measured point's coordinates are used to recalculate coordinates of topo points saved before correction and to calculate the current 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 job. Correct Base dialog allows you to return to previous corrections at any moment.
