GMTLEGS(l)

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 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. 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 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, 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
