DESCRIPTION¶
gmtlegs will report the name of all the cruises that happened to be
wholly or partially inside the specified region. As an option, only those
cruises that collected a certain type of data can be reported.
- -R
- west, east, south, and north specify the
Region of interest, and you may specify them in decimal degrees or in
[+-]dd:mm[:ss.xxx][W|E|S|N] format. Append r if lower left and
upper right map coordinates are given instead of w/e/s/n. The two
shorthands -Rg and -Rd stand for global domain (0/360 and
-180/+180 in longitude respectively, with -90/+90 in latitude).
Alternatively, specify the name of an existing grid file and the -R
settings (and grid spacing, if applicable) are copied from the grid.
OPTIONS¶
No space between the option flag and the associated arguments
- -G
- Report cruises that collected Gravity data. [Default is any
data].
- -M
- Report cruises that collected Magnetics. [Default is any
data].
- -T
- Report cruises that collected Topography. [Default is any
data].
- -L
- Long output, i.e. cruisenames and data types available.
[Default is cruisenames only].
- -V
- Selects verbose mode, which will send progress reports to
stderr [Default runs "silently"].
EXAMPLES¶
To find all cruises around Hawaii that collected gravity and topography:
gmtlegs -R-162/-152/18/25
-G -T > hawaii_gt.legs
To find all cruises with magnetics:
gmtlegs -R0/360/-90/90
-M > all_m.legs
