NAME

       grdpaste - 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 neces-
       sary 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

NAME

       grdinfo - Get information about the contents of a 2-D grd file

SYNOPSIS

       grdinfo grdfiles [ -C ] [ -D ] [ -F ] [ -L1 ] [ -L2 ] [ -M ] [ -V ]

DESCRIPTION

       grdinfo reads a 2-D binary grd file and reports various statistics for the (x,y,z) data in the grdfile. The output information contains the
       minimum/maximum values for x, y, and z, where the min/max of z occur, the x- and y-increments, and  the	number	of  x  and  y  nodes,  and
       [optionally] the mean, standard deviation, and/or the median, L1 scale of z, and number of nodes set to NaN.

       grdfile
	      The name of one or several 2-D grd files.

OPTIONS

       No space between the option flag and the associated arguments.

       -C     Formats  the report using tab-separated fields on a single line. The output is w e s n z0 z1 dx dy nx ny [ x0 y0 x1 y1 ] [ med scale
	      ] [ mean std rms] [n_nan].  The data in brackets are output only if the corresponding options -M, -L1, -L2, and -M are used, respec-
	      tively.

       -D     Report grid domain and x/y-increments using dd:mm:ss[.fff] notation [Default is decimal].  Does not apply to the -C option.

       -F     Report grid domain and x/y-increments world mapping format [Default is generic].	Does not apply to the -C option.

       -L1    Report median and L1 scale of z (L1 scale = 1.4826 * Median Absolute Deviation (MAD)).

       -L2    Report mean and standard deviation of z.

       -M     Find and report the location of min/max z-values, and count and report the number of nodes set to NaN, if any.

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

EXAMPLES

       To obtain all the information about the data set in file hawaii_topo.grd, try

       grdinfo -L1 -L2 -M hawaii_topo.grd
