thanks. Somehow I missed the "override" implications of -a when I
looked at gdal_translate.<br>
And yes, I believe the coordinates are OK in my file, just a bad
SRS.<br>

I can use listgeo to get a file of the all the tags, edit
the coordinate system to the correct value, then use tiffcp
on each file to strip out the tags and then use geotifcp to
put back the correct ones, but I suspect there's a better
way, perhaps using gdalwarp with the -to option set to
override the input SRS, creating a trivial warp? Or maybe
something simpler that I'm not seeing.<br>
