SYNOPSIS
     r.out.hdf
     r.out.hdf help
     r.out.hdf [-q] input=_n_a_m_e [output=_n_a_m_e] [mult=_v_a_l_u_e]

DESCRIPTION
     _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.

COMMAND LINE OPTIONS
     Flags

     -_q   Run quietly

     Parameters

     _i_n_p_u_t
          Raster file to be converted.

     _o_u_t_p_u_t
          Name for new hdf file.
          default: <rasterfilename>.hdf

     _m_u_l_t Floating point multiplier. (file.hdf = cellfile *  mul-
          tiplier)

     NCSA HDF is a multi-object  file  format  developed  by  The
     National  Center  for  Supercomputing  Applications at Cham-
     paign, Illinois for the transfer of graphical and  floating-
     point data between machines.  The format defines both a ras-
     ter 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 numbers, 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
     visualization  applications  which use the HDF format.  Some
     commercial applications also support HDF.  For more informa-
     tion, use the NCSA anonymous ftp server _f_t_p._n_c_s_a._u_i_u_c._e_d_u or
