I often get the case where some of the drone images are not geotagged, either because the flight was rushed, or the drone flew at some point into some kind of canyon/interior.
In those cases, images get geotagged with a valid coordinates system, but null GPS coordinates.
RC then tries to use those null coordinates as an absolute pose image prior. The resulting alignment is skewed and the residuals show which images are at fault.
The usual workaround is to select those faulty images, set their prior pose to "unknown", and update.
It would be nice for RC to detect those incoherent coordinates and not use them as prior position.
