grdpaste(1) GMT grdpaste(1)
NAME
grdpaste - Join two grids along their common edge
SYNOPSIS
grdpaste file_a.nc file_b.nc -Goutfile.nc [ -V[level] ] [ -fflags ]
Note: No space is allowed between the option flag and the associated
arguments.
DESCRIPTION
grdpaste will combine file_a.nc and file_b.nc into outfile.nc by past-
ing them together along their common edge. Files file_a.nc and
file_b.nc 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. Note: For geographical grids, you may have
to use -f to handle periodic longitudes unless the input grids are
properly recognized as such via their meta-data.
REQUIRED ARGUMENTS
file_a.nc
One of two files to be pasted together.
file_b.nc
The other of two files to be pasted together.
-Goutfile.nc
The name for the combined output.
OPTIONAL ARGUMENTS
-V[level] (more a|)
Select verbosity level [c].
-f[i|o]colinfo (more a|)
Specify data types of input and/or output columns.
-^ or just -
Print a short message about the syntax of the command, then
exits (NOTE: on Windows just use -).
-+ or just +
Print an extensive usage (help) message, including the explana-
tion of any module-specific option (but not the GMT common
options), then exits.
-? or no arguments
Print a complete usage (help) message, including the explanation
of all options, then exits.
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 apackinga of grids, writing out floating point
data as 1- or 2-byte integers. (more a|)
EXAMPLES
Suppose file_a.nc is 150E - 180E and 0 - 30N, and file_b.nc is 150E -
180E, -30S - 0, then you can make outfile.nc which will be 150 - 180
and -30S - 30N by:
gmt grdpaste file_a.nc file_b.nc -Goutfile.nc -V -fg
