  Hallo,
   I successfully exported elavation.dem and read it from xv-2.21.
   From grass4.0 I have use command : 
   r.out.tga input=elvation.dem output=/mydir/elavation.tga .

   After I have pbmplus (You can have pbmplus routines from an ftp site)
   routines to convert tga image into ppm with command :
   ppbmplus/tgatoppm /mydir/elevation.tga > /mydir/elvation.ppm

   This file is readable (or updating) from xv-2.21 .


   Note : elevation.tga is big  1995540 bytes
          elevation.ppm is big  1995047 bytes
