[GRASS-user] How to make a conversion of ERSI Grid ASCII==>USGS DEM?

[Illidan]

Hello Hamish,

You're right. The file format is exactly as you say. In fact I was
just about to paste the beginning of that file.

By now I'm successful with importing the ESRI ASC by r.in.arc

> r.in.arc input=srtm_60_04.asc output=beijing
CREATING SUPPORT FILES FOR beijing

However, when I try

 r.out.gdal input=beijing output=beijing.dem format=USGSDEM

it replies with "Error: value <USGSDEM> out of range for parameter <format>
       Legal range:
AAIGrid,BMP,BSB,DTED,ELAS,ENVI,FIT,GIF,GTiff,HFA,JPEG,MEM,MFF,MFF2,NITF,PAux,PNG,PNM,VRT,XPM
''

In fact when I run it with "-l" option as "r.out.gdal input=beijing
output=beijing.dem -l'', it responses with a listing including
'USGSDEM' that looks like:

  FIT: FIT Image
  RMF: Raster Matrix Format
  RST: Idrisi Raster A.1
  INGR: Intergraph Raster
  GSAG: Golden Software ASCII Grid (.grd)
  GSBG: Golden Software Binary Grid (.grd)
  USGSDEM: USGS Optional ASCII DEM (and CDED)
  ADRG: ARC Digitized Raster Graphics


So I'm confused whether USGSDEM is valid or not.
