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
