NAME
     ISMcell2scat - Converts a GRASS raster map layer into an ISM
     scattered data file.
     (GRASS Raster Data Export Program)

SYNOPSIS
     ISMcell2scat
     ISMcell2scat help
     ISMcell2scat GRASS_file_name ISM_file_name

DESCRIPTION
     ISMcell2scat allows a user to create a scattered data file
     for use in Interactive Surface Modeling (ISM) from an
     existing GRASS raster map layer.

COMMAND LINE OPTIONS
     Parameters:

     GRASS_file_name     Name of a binary GRASS raster map input
                         file.

     ISM_file_name       Name to be assigned to ISM scattered
                         data file created.

NOTES
     For each (x,y) position in the original cell file,
     ISMcell2scat assigns an attribute for the scattered data
     file.  This program is useful when the user wants to take
     advantage of smoothing capabilities of ISM.

     The user should note that the maximum ISM grid size is 512 x
     512, yet GRASS cell files are often much larger.
     ISMcell2scat currently resamples larger cell files at 512 x
     512 resolution.  To avoid losing information, the user may
     want to resize the grass cell file prior to exporting the
     data.

     Since the scattered data file created by ISMcell2scat is
     placed in the current directory, the user should run
     ISMcell2scat from the ISM file directory or move the new
     file to the ISM file directory.  In order to use the
     scattered data file, the user must also add it to the ISM
     table of contents (.toc file) by choosing option 3
     (edit/create file) under FILE OPERATIONS.
