I have some tiles of OS raster mapping and their associated TFW georeferencing files. The GR files are in the same folder as the raster data and have the same names, ie TQ21.tif/TQ21.tfw.

In QGIS 1.8, I add a tile as a raster layer and choose the OSGB 1936/British National Grid CRS. When I load the next tile over, it loads in the correct place. Fine so far.

However, the problem is that the scale is completely out - to view a tile I have the onscreen scale indicator at around 1:365000000! If I go to Raster > Miscellaneous > Information there is nothing in the Raster Info box, but the fact that the tiles load in their correct place suggests QGIS *is* reading the GR files.

Am I missing something?
