NAME

       grdpaste - Paste together two .grd files along a common edge.

SYNOPSIS

       grdpaste file_a.grd file_b.grd -Goutfile.grd [ -V ] [ -f[i|o]colinfo ]

DESCRIPTION

       grdpaste  will combine file_a.grd and file_b.grd into outfile.grd by pasting them together
       along their common edge.  Files file_a.grd and file_b.grd must have the same  dx,  dy  and
       have  one edge in common.  If in doubt, check with grdinfo and use grdcut and/or grdsample
       if necessary to prepare the edge joint.  For geographical grids, use -f to handle periodic
       longitudes.

       file_a.grd
              One of two files to be pasted together.

       file_b.grd
              The other of two files to be pasted together.

       -Goutfile.grd
              The name for the combined output.

OPTIONS

       -V     Selects  verbose  mode,  which  will  send progress reports to stderr [Default runs
              "silently"].

       -f     Special formatting of input and/or output  columns  (time  or  geographical  data).
              Specify  i  or  o  to  make  this apply only to input or output [Default applies to
              both].  Give one or more columns (or column ranges) separated by commas.  Append  T
              (absolute calendar time), t (relative time in chosen TIME_UNIT since TIME_EPOCH), x
              (longitude), y (latitude), or f (floating point) to each  column  or  column  range
              item.  Shorthand -f[i|o]g means -f[i|o]0x,1y (geographic coordinates).

GRID FILE FORMATS

       By  default  GMT  writes  out grid as single precision floats in a COARDS-complaint netCDF
       file format.  However, GMT is able to produce grid files in many other commonly used  grid
       file formats and also facilitates so called "packing" of grids, writing out floating point
       data as 2- or 4-byte integers. To specify the precision, scale and offset, the user should
       add  the  suffix =id[/scale/offset[/nan]], where id is a two-letter identifier of the grid
       type and precision, and scale and offset are  optional  scale  factor  and  offset  to  be
       applied  to  all  grid  values,  and nan is the value used to indicate missing data.  When
       reading grids, the format is generally automatically recognized. If not, the  same  suffix
       can  be  added  to  input grid file names.  See grdreformat(1) and Section 4.17 of the GMT
       Technical Reference and Cookbook for more information.

       When reading a netCDF file that contains multiple grids, GMT will read,  by  default,  the
       first  2-dimensional  grid  that  can  find in that file. To coax GMT into reading another
       multi-dimensional variable in the grid file, append  ?varname  to  the  file  name,  where
       varname  is the name of the variable. Note that you may need to escape the special meaning
       of ? in your shell program by putting a backslash in  front  of  it,  or  by  placing  the
       filename and suffix between quotes or double quotes.  The ?varname suffix can also be used
       for output grids to specify  a  variable  name  different  from  the  default:  "z".   See
       grdreformat(1)  and  Section  4.18  of  the  GMT Technical Reference and Cookbook for more
       information, particularly on how to read splices of 3-, 4-, or 5-dimensional grids.

EXAMPLES

       Suppose file_a.grd is 150E - 180E and 0 - 30N, and file_b.grd is 150E - 180E,  -30S  -  0,
       then you can make outfile.grd which will be 150 - 180 and -30S - 30N by:

       grdpaste file_a.grd file_b.grd -G outfile.grd -V -fg
