[mapserver-users] Mapserver and raster layers

[Christopher Dedels]

Hmmm...missed that one.  But changing the units to dd still doesn't have any
effect.

I am using mapserver 4.8.1.  DEBUG is not an option in this version.
mapserv -v produces the following output:

MapServer version 4.8.1 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP
OUTPUT=SVG SUPPORTS=PROJ SUPPORTS=FREETYPE SUPPORTS=WMS_SERVER SUPPORTS=GEOS
INPUT=EPPL7 INPUT=POSTGIS INPUT=GDAL INPUT=SHAPEFILE

My request uri is:
http://localhost/cgi-bin/mapserv?MAP=/tmp/mapNl7O7H.map&LAYERS=ALL&MODE=MAP

gdalinfo output for my raster file is:
