[mapserver-users] New to mapserver; question about USGS DRG/GeoTIFF files

[Roger André]

Hi Jon,

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:

  PROJECTION
    "init=epsg:4326"
  END

and your usgs LAYER (the name should be quoted btw) should have the UTM
projection defined in it, like this:

LAYER
  NAME "usgs"
  PROJECTION  "init=epsg:26719" END

Best of luck,

Roger
