## 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 min
                  utes  [and  seconds],  use  the  dd:mm[:ss] format.
                  Append r if lower left and upper right map  coordi
                  nates 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 avail
                  able. [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
