    NAME

    mbm_grdinfo - Macro to get information regarding a GMT grd file when the
    region of interest is a subset of the area covered in the
    input file.

    VERSION

    Version 5.0

    SYNOPSIS

    mbm_grdinfo -Iinfile [-Rw/e/s/n -H -V]

    DESCRIPTION

    mbm_grdinfo is a macro to get information
    regarding a GMT grd file when the
    region of interest is a subset of the area covered in the
    input file. If no bounds are specified, the program grdinfo
    is called directly.  If longitude and latitude bounds are
    specified, then the specified region is cut from the input
    file using the macro mbm_grdinfo, and the information is
    obtained from the subset temporary grd file using grdinfo.

    OPTIONS

    -H

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

    infile

    Sets the filename of the input GMT grid file. This file must be
    in the GMT NetCDF GRD format.
    -R

    w/e/s/n

    Sets the bounds of the area of interest in the grid file. The
    information reported will pertain to this area only.
    -V

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

    EXAMPLES

    Suppose that we have used mbgrid to obtain a
    topography grid file called KohalaA_bath.grd in the GMT NetCDF
    GRD format:

            mbgrid -Idatalist \

                    -OKohalaA_bath \

                    -R-155.72855/-155.31928/20.09488/20.47645 \

                    -E30.0/0m! -A2 -N -G3 -C1 -V

    Further suppose that one wishes to determine the
    depth range in a smaller area with
    bounds of 155 degrees 31 minutes W to 155 degrees 26 minutes W
    in longitude and 20 degrees 13 minutes N to 20 degrees 18 minutes N
    in latitude. The following will suffice:

            mbm_grdinfo -I KohalaA_bath.grd                 -R-155:31/-155:26/20:13/20:18           -V
