[Gvsig_english] gvsig 1.9 and georeferencing

[Benjamin Ducke]

Actually, the GDAL software includes "gdalwarp", which does
rubber-sheeting, using a thing plate spline algorithm.
You might just want to give that a try. It's easy to use from
the command line:

   gdalwarp -tps -gcp ... -gcp .. -gcp ... in.tif out.tif

Maybe it would also be possible to have the gvSIG georeferencer
call "gdalwarp" in the background for rubber-sheeting?

Best,

Ben
