Richard, I can strip the crs off using gdal_translate and setting a Baseline
profile. But I wanted to test what happens when a raster is already
georeferenced.

I have no good reason to say this other than a niggling suspicion[1] but, yes I
think it can.
-ramon.
[1] We occasionally have problems with the georeferencer, where it tries to
rotate an image that shouldn't need to be. It's rare enough that I haven't been
able to track it down properly, but t
Ok, i got it.
The reason it doesn't work is probably easily explained: the source X/Y are
considered as raster space coordinates, while I thought that having the
raster a CRS assigned this was kept into account during the warping.
Probably manual re-georeferencing is conceptually unuseful, outside
Sure Baren, this was just an exercise ;)
I wanted to test regeoreferencing a raster and compare manual georeferencing
against reprojection.
I'm wondering if manually regeoreferencing an already georeferenced raster
can break things...

Hi Giovanni,
I don't understand: you want to change a projected raster (in CRS 3003) to
another projection (23023), so why do you need the georeferencing plugin?
The data is already referenced, so it sounds to me you just want to
re-project it, using the Raster > Warp menu.
Or am I missing someth
Thanks for the reply.
My raster infos are:
PROJCS["Monte Mario / Italy zone 1",
GEOGCS["Monte Mario",
DATUM["Monte_Mario",
SPHEROID["International 1924",6378388,297.00014,
AUTHORITY["EPSG","7022"]],
AUTHORITY["EPSG","6265"]],
