<DIV><FONT size=2> GDAL does not support .ers files
directly. However, since most .ers header files reference a data
file of type "BIL" it is possible to hand craft an ESRI .hdr file header (which
GDAL does support) to reference the the BIL file. And as the .hdr header
does not include a coordinate system definition, you would need to add a
"-a_srs" to your gdal_translate command line.</FONT></DIV>
