Hi Jon,<br><br>You don't appear to have any projection info in your map file. Since you have "UNITS dd" in it, I assume you want to display the map in lat/lon WGS84? If so, your MAP file needs an entry that looks like this:<br>
<br> PROJECTION<br> "init=epsg:4326"<br> END<br><br>and your usgs LAYER (the name should be quoted btw) should have the UTM projection defined in it, like this:<br><br>LAYER<br> NAME "usgs"<br> PROJECTION "init=epsg:26719" END<br>

Hi -<br>
<br>
I'm new to Mapserver, and so far impressed by it's capabilities. I've installed the FGS package via fgs-mapserver_basic_5.6.0-fgs_9.5-linux-i386.bin and played with their demo program.<br>
<br>
I'm having a problem with a USGS DRG file that is encoded as a GeoTIFF file. It doesn't display on the webpage, and I'm not sure where to start debugging this. I've checked the file with gdalinfo:<br>
