       _r_._o_u_t_._h_d_f allows a user to create a data file in NCSA Hierarchical Data
       Format (HDF) from an existing GRASS raster file.

       NCSA HDF is a multi-object file format developed by The National Center
       for Supercomputing Applications at Champaign, Illinois for the transfer
       of  graphical  and  floating-point  data  between machines.  The format
       defines both a raster type and a SDS type.  The later  is  basically  a
       highly  structured multi-dimensional array of floating point values.  A
       single HDF file may contain more than one SDS, but using _r_._o_u_t_._h_d_f will
       create  a  single  HDF file containing a single 2-dimensional SDS.  The
       HDF raster format consists of a palette and a 2D array  of  8-bit  num-
       bers,  but  _r_._o_u_t_._h_d_f  does  not  yet create this format file, so color
       tables are not transferrable.


       NCSA distributes the HDF library and several public  domain  visualiza-
       tion  applications  which use the HDF format.  Some commercial applica-
       tions also support HDF.	For more information, use the  NCSA  anonymous
