Dear João,
thanks for posting this code excerpt, I am not aware of any other example
around for georeferencing an image via GCP (is there..?).
Regarding your code: why are you defining a warp-transform from pixels to
coordinates:
> WarpTransform2D wt = new WarpTransform2D(src, dst, deg);
while using it to define the derived "Image" CRS which is supposed to be fed
with the transform from coordinates to pixels instead?
> DefaultDerivedCRS derivedCRS = new DefaultDerivedCRS("imageCRS",
> srcCrs, wt, DefaultCartesianCS.GENERIC_2D);
Is this a mistake/typo?
