Yan,

This message might be more specifically sent to the gdal-dev mailing list.

The GDAL AIG driver does have at least partial support for reading the .clr
file and translating into a colormap.  Do you have a .clr file with your
.adf files?  If not then the dataset apparently lacks a color table.  If so,
consider submitting a bug report via the GDAL bugzilla with in formation on
how to get the dataset in question.
