USGS DEM in mapserver

[Pietro Giannini]

Of course!!! :-)

I forgot to define the LAYER projection ...
now it work.

(I use world files because Gtopo dataset is tiled,
and come already with the world files. Better way can be also to define a
TILEINDEX and an index shapefile, so all Gtopo extension becomes one only
layer.)

many thanks! 
bye
