Good evening,
I need to do a local grid for one of our projects. I know the local coordinates for six points and their WGS84 equivalent. Initially, I thought to do Site Calibration but after read some TBC tutorials I understand that the points have to be surveyed with GNSS. To have just the WGS84 coordinates is not enough.
I can’t survey the points again. They have been destroyed.
Is there a way to create the local grid based in the available info? Using TBC, if possible.
Regards

No, they don't need be brought in as GPS survey.
Either import them from a CSV file, or manually create a point via CAD->Create Point and change the coordinate type to "Global". Best is you add a prefix to the GPS point.
The grid point in example is "1" then call the GPS point "1-GPS".


There seems to be some kind of bug in the point selector, if the "GPS"-Point has also got local coordinates the selection fails, claiming the point has no global coordinates.
