NAME

       grdclip - Clipping of range in grdfiles.

SYNOPSIS

       grdclip input_file.grd -Goutput_file.grd [ -Sahigh/above ] [ -Sblow/below ] [ -V ]

DESCRIPTION

       grdclip	will set values < low to below and/or values > high to above. Useful when you want all of a continent or an ocean to fall into one
       color or grayshade in image processing, or clipping of the range of data values is required. above/below can be any number or  NaN  (Not  a
       Number).  You must choose at least one of -Sa or -Sb.

       input_file.grd
	      The input 2-D binary grdfile.

       -G     output_file.grd is the modified output grdfile.

OPTIONS

       -Sa    Set all data[i] > high to above.

       -Sb    Set all data[i] < low to below.

       -V     Selects verbose mode, which will send progress reports to stderr [Default runs "silently"].

EXAMPLES

       To set all values > 70 to NaN and all values < 0 to 0 in file data.grd, try:

       grdclip data.grd -Gnew_data.grd -Sa70/NaN -Sb0/0 -V
