       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
