Hi,<br><br>I have Alabama geotiff tiles which are showing up in Virginia within mapserver. If you look at the original gdalinfo against one of the tiles you will see that the corner coordinates are within Alabama, but within MapServer if you do on the fly projection(EPSG:26929 to EPSG:4326) it instead shows up within the state of Virginia. I also used gdalwarp to change the projection from EPSG:26929 to EPSG:4326 and then displayed within mapserver without having to reproject on the fly and it also shows up within Virginia. Note: when running gdalinfo on the gdalwarp file which was reprojected to EPSG:4326 it also has the coordinates within the state of Virginia.
