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
