The global set of Landsat images on GEOCOVER https://zulu.ssc.nasa.gov/mrsid/mrsid.pl is on UTM/WGS projection but with the Southern hemisphere tiles as UTM zones in the N with negative coordinates. For example, a tile that should be at 18S is actually 18N with negative coordinates ("Non-standard UTM definition: For the southern hemisphere, the GeoTiff files contain positive zone numbers with negative northing coordinates") https://zulu.ssc.nasa.gov/mrsid/docs/GeoCover_circa_2000_Product_Description.pdf
As we have some vector layers on geographic coordinates WGS84 and a Geocover tile for 18S,
I've set the project as 18S, enabled CRS reprojection on the fly, and set the raster CRS to 18N. Unfortunately, QGIS does not display the raster, even selecting zoom to layer extent. (Using Mimas). This is probably not a problem of QGIS, the Geocover projection is just wrong, but would like to know if there could be a way to circumvent this problem to be able to use GEOCOVER tiles of the S hemisphere within QGIS. A way could be making a world file with the Georeferencer plugin, but perhaps there is a more general way.
