Hi All,
I just went through the painful process of fixing a badly geo-referenced vector against another vector. I used v.transform and a correspondence file to do the work. The module works really well. However I wonder whether it would be possible to modify the existing geo-referencing plugin or a vector equivalent of i.points to facilitate the process of creating a correspondence file for one vector against another?
This would make the job much easier and also allow users to check up RMS errors and drop offending points.
Thanks,
rsb

See i.vpoints
As an output it will make a POINTS file for i.rectify, but perhaps that
could be easily changed to output parameters for v.transform too. It is
already calculating the params for RMS checks and the
reverse-projection vector overlay.
