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
