Thanks Zoltan!<br /><br />I tried immediately and it work well ... but MS
does not reproject the raster!<br />The only way to display correctly the
raster is apply a lat/lon projection to the map, the same of the
raster.<br /><br />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.<br /><br />I used .tif rasters, georeferenced with world files,
and MS reproject them without problem.<br /><br />Another way to
georeference .dem rasters?<br />Anyone can help?<br /><br />thanks, bye<br

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