For datasets going through the OGDI library in GDAL you need to use
a somewhat esoteric name for the dataset.  For my ADRG dataset I use:


The "gltp:/adrg" portion are fixed with gltp indicating this is an OGDI
request, and adrg indicating the driver to use.  The rest is the path to
the dataset.  Note that in this case the TPUS0101 directory is below
the directory with the THF and CPH directory, and the TPUS0101 directory
includes .IMG, .QAL, .OVR and .GEN files.

Good luck!
