grdcut
GRDCUT(l) GRDCUT(l)
NAME
grdcut - Extract a subregion out of a .grd file
SYNOPSIS
grdcut input_file.grd -Goutput_file.grd -Rwest/east/south/north[r] [ -V ]
DESCRIPTION
grdcut will produce a new output_file.grd file which is a subregion of input_file.grd. The subregion is specified with
-Rwest/east/south/north as in other programs; the specified range must not exceed the range of input_file.grd. If in doubt, run grdinfo to
check range. Complementary to grdcut there is grdpaste, which will join together two grdfiles along a common edge.
input_file.grd
this is the input .grd format file.
-Goutput_file.grd
this is the output .grd format file.
-R west, east, south, and north specify the Region of interest. To specify boundaries in degrees and minutes [and seconds], use the
dd:mm[:ss] format. Append r if lower left and upper right map coordinates are given instead of wesn. This defines the subregion to
be cut out.
OPTIONS -V Selects verbose mode, which will send progress reports to stderr [Default runs "silently"].
EXAMPLES
Suppose you have used surface to grid ship gravity in the region between 148E - 162E and 8N - 32N, and you do not trust the gridding near
the edges, so you want to keep only the area between 150E - 160E and 10N - 30N, then:
grdcut grav_148_162_8_32.grd -Ggrav_150_160_10_30.grd -R150/160/10/30 -V
