NAME

       gmtlegs - Find cruises in a given region

SYNOPSIS

       gmtlegs -Rwest/east/south/north[r] [ -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, and you may specify
              them in decimal degrees or in  [+-]dd:mm[:ss.xxx][W|E|S|N]  format.   Append  r  if
              lower  left  and upper right map coordinates are given instead of w/e/s/n.  The two
              shorthands -Rg and -Rd stand for global domain (0/360 and  -180/+180  in  longitude
              respectively,  with  -90/+90  in  latitude).  Alternatively, specify the name of an
              existing grid file and the -R settings (and grid spacing, if applicable) are copied
              from the grid.

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:

       gmtlegs -R-162/-152/18/25 -G -T > hawaii_gt.legs

       To find all cruises with magnetics:

       gmtlegs -R 0/360/-90/90 -M > all_m.legs
