grdpaste(1) Paste together two .grd files along a common edge.

SYNOPSIS

grdpaste file_a.grd file_b.grd -Goutfile.grd [ -V ]

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.
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"].

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 -Goutfile.grd -V
