[gdal-dev] gdal translate error converting ArcGRID binary to ASCII

[P Kishor]

I have a few ArcGRID binary files (.adf extension) that I want to
convert to ArcGRID ASCII (so I may open them with QGIS).

An old email from Frank W indicates this can be done with gdal_translate. See

http://mapserver.gis.umn.edu/data2/wilma/mapserver-users/0405/msg00005.html

I was, however, unable to do this successfully. Here is my saga --
