    NAME

    mbm_arc2grd - Macro to convert an ArcView ASCII grid
    to a GMT  grid file in the GMT NetCDF grid format.

    VERSION

    Version 5.0

    SYNOPSIS

    mbm_arc2grd -Iarcfile -Ogrdfile [-H -V]

    DESCRIPTION

    mbm_arc2grd is a macro to convert a ArcView
    ASCII grid to an GMT grid file in the
    GMT NetCDF grid format. This allows users to import the grid
    into GMT. The grid will have the same grid interval in both
    longitude and latitude.
    The macro first obtains the bounds, dimensions, and grid
    cell size of the grid by parsing the six line header.
    The macro then reformats the gridded data as xyz data,
    writing it to a temporary file. This temporary file is
    processed using the GMT program xyz2grd,
    yielding a GMT GRD format grid file.

    OPTIONS

    -H

    This "help" flag cause the program to print out a description
    of its operation and then exit immediately.
    -I

    arcfile

    Sets the filename of the input ArcView ASCII grid.
    -O

    grdname

    Sets the filename of the output GMT grid file. This file will be
    in the GMT NetCDF GRD format.
    -V

    The -V option causes mbm_arc2grd to print out status messages.

    EXAMPLES

    Suppose that we have obtained an ascii ArcView grid called
    kohalab.asc. To translate this file to a GMT grd file,
    the following will suffice:

            mbm_arc2grd -I kohalab.asc -O kohalab.grd -V

    Running the example above produced the following output:

            Program mbm_arc2grd status:

                    Input ArcView ASCII  file: kohalab.asc

                    Output GRD file:           kohalab.grd

                    Grid dimensions:  1597  1431

                    Grid cell sizes:  0.0001914456033  0.0001914456033

                    Grid bounds:      -155.72855  -155.423002817133    20.1318  20.405567212719

            Running xyz2grd...

            xyz2grd: nx = 1597  ny = 1431
