Jason -

If you're using USGS DRGs, as you appear to be, those DRGs come in the
UTM projection.  Have you reprojected those images to a "geographic" or
lat/lon type of image?  Your "extent" line indicates extents in decimal
degrees, but that's not how the DRGs usually come.  You should look at
either the ESRI world file (.TFW) or the GeoTIFF tags in your TIFF image
to check the spatial extents of the image.

I am trying to use raster data within mapserver, .tif image with a
.tfw.  gdal support is compiled within mapserver.
My mapfile looks like this.
**************************************
Map
 name drgviewer
 extent -110 30 -108 32
 size 400 400
 shapepath "../downloads/drgs/24k/clipped"
 units meters

Web
  imagpath "/var/www/html/tmp/"
  imageurl "/tmp"
 End

Layer
 name "drg_c1"
 data "31109c1c.tif"
 type raster
 status on
End
End
**********************************************
But all I get is a blank image?  Is there anyone that can help me with
this problem?
What am I doing wrong?

Thanks,
Jason
