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
