This directory contains graphic files that can be used to plot copies of the
             map on a variety of large format plotters.

            The *.hp2 files can be plotted on Hewlett-Packard plotters from Unix or           
            Linux operating systems.  The postscript files can be plotted directly in Unix
            or Linux operating systems.  On Windows or Macintosh platforms it is necessary
            to open the file in a graphics application which supports this format.  To print
            the entire map the page size must be set at 44 by 38 inches, landscape.  It is 
            suggested that the graphics application documentation be consulted for best results.
