NAME
gmtlegs - Find cruises in a given region
SYNOPSIS
gmtlegs -Rwest/east/south/north [ -G ] [ -M ] [ -T ] [ -L ]
[ -V ]
DESCRIPTION
gmtlegs will report the name of all the cruises that hap-
pened 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. 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.
OPTIONS
No space between the option flag and the associated argu-
ments
-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, try
gmtlegs -R-162/-152/18/25 -G -T > hawaii_gt.legs
To find all cruises with magnetics, try
gmtlegs -R0/360/-90/90 -M > all_m.legs
