Steve,<br>
<br>
First, you may not be aware that gdal_translate writes TIFF by default,<br>
even if you use the extension .img. So if you want a .img output
you<br>
would need to specify -of HFA on the commandline.<br>
<br>
The warning indicates that there was too much metadata in the source<br>
file to properly store in the GeoTIFF so it was discarded. Often<br>
this won't matter to you.<br>

<br>
This means it is your responsibility to ensure that the shapefile<br>
and the .img file are in the same coordinate system since the command<br>
cannot determine it from the .shp file. The warning is perhaps a
bit<br>
too dramatic.<br>
<br>
