Thomas, I would start by creating a colour table with each group containing the same shade of grey. This will ease the polygonization by avoiding duplicates. There will be three or four (RGB/RGBA) bands from the colour table but you can just consider one band during polygonization. On Tue, May 4

Thanks Peter, good points. One further question: even if the georeferenced map as a whole is distorted due to too few control points, the control points *themselves* should always be projected to their exact specified georeferenced location, right? At least that is wthat I thought was the diffe
