DATA FORMATS
Data are provided as binary integers in exactly the same format
as SRTM30.  The files must be uncompressed with gzip and are 16-bit
big endian byte order. 

Example:
 r.in.bin -sb input=e020n40.Bathmetry.srtm output=e020n40_topex bytes=2 north=40 south=-10 east=60 west=20 r=6000 c=4800
 r.colors e020n40_topex rules=etopo2

Enjoy
