Hi Frank,

I ran gdalinfo with debug and it produced the following results:

alan at stratford:~/gdal/gdal-svn-trunk-2009.12.14 15% apps/gdalinfo --debug on
/nashome/noBackup/map_CDs/UK_1to50k/03/ASRP/GUK166/GUK16601.IMG
SRP: NAM=GUK166
SRP: SCA=50000
SRP: ZNA=3
SRP: PSP=66.700000
GDALPamDataset: In destructor with dirty metadata.
ERROR 4: `/nashome/noBackup/map_CDs/UK_1to50k/03/ASRP/GUK166/GUK16601.IMG'
not recognised as a supported file format.

gdalinfo failed - unable to open
'/nashome/noBackup/map_CDs/UK_1to50k/03/ASRP/GUK166/GUK16601.IMG'.
GDAL: GDALDeregister_GTiff() called.

Does this help diagnose the problem?

The GUK16601.IMG file has the following associated files; GUK16601.GER,
GUK16601.GEN, GUK16601.SOU and GUK16601.QAL.

I am investigating the legalities regarding sending the data file, or
possibly finding other files that exhibit the same issues. Do you know of
any data online that I could use?

Thanks for your interest,
Alan
