<div dir="ltr">You should probably first get it sorted with gdalinfo before messing with mapserv. So you're doing gdalinfo on exactly the same file on your old and new systems and getting those results? What version of gdal on the two? Use "gdalinfo --version" and what type of file is it? Does it have an accompanying world file? If so, what happens if you hide the world file?<div><br></div><div>Regarding your inline projection definitions in your map file, they are canceling each other out. The definition at the "top" of your file is the projection that your map fill be served out in. The definition within a LAYER block tells mapserv what projection that layer is in. So if the layer is different than the map, then mapserv will transform it, but if they are the same then mapserv does no transformation.</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Feb 15, 2017 at 8:07 AM, Cechini, Matthew F.
