[Qgis-user] Problem with adding GeoTIFF raster

[Kieron Dunbar]

I tried to import one of the GeoTIFF rasters from www.ordnancesurvey.gov.uk into QGis, but it seems to ignore the co-ordinates reported by gdalinfo, as it puts the top left corner at 0,0 with a scale of 1 pixel per unit. Is there a way I can put this file in the correct position? I haven't used QGis or GDAL before, so I apologise if I have missed something obvious?

The properties gdalinfo reports are as follows (slightly abbreviated):

Driver: GTiff/GeoTIFF

Many thanks.
