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
