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
