I'm trying to georeference some maps of Namibia and am having trouble. The projection stated on the map is the "Gauss Conform Central Meridian 15deg E. Bessel's Spheroid". I've tried using South African CRS : HBK_NO_15 and CAPE_NO_15 on the assumption that perhaps the "NO_15" refers to the central meridian. However, when I rasterize the files, they are upside down.
Does anyone know why this would be?
