Thanks Zoltan!
I tried immediately and it work well ... but MS
does not reproject the raster!
The only way to display correctly the
raster is apply a lat/lon projection to the map, the same of the
raster.
In the same directory of the .dem is a world
file, with the same name of the Gtopo tile and extension ".wld",
I tried also to rename the world file to ".dmw", without
result.
I used .tif rasters, georeferenced with world files,
and MS reproject them without problem.
Another way to
georeference .dem rasters?
Anyone can help?
thanks, bye

Hi Pietro,
I'm using Gtopo data. Simpli add a layer to
your map file.
AFAIK gdal can read it, it may depend on gdal
version.
My layer definition looks like:
LAYER
NAME
"e020n90"
DATA "e020n90.dem"
TYPE
RASTER
STATUS DEFAULT
CLASSITEM '[pixel]'
CLASS
NAME "Nodata"
EXPRESSION ([pixel] < 1)
COLOR 0 0 255
END
CLASS
NAME "0 - 50
m"
EXPRESSION ([pixel] >= 1 AND [pixel] < 50)
COLOR 0 119 32
END
...
END #of layer
Bye
Zoltan
