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>
