I want to reproject a tiff raster file from projection A (ETRS89/UTM Zone 32) to projection B (DHDN/Gauss-Kruger zone 2). The two projections have a different datum so I have to use a datum transformation (NTv2 BETa2007 in my case). I want to create a new raster file with projection B because I want to use it in another software. So reprojection on-the-fly is not what I need.
I have tried Raster > Transform (or similar - I do not know the English menu) but I can not see how to define a datum transformation here.
How can I do a permanent reprojection of a raster file in Qgis with a datum transformation?
