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 topogra-
       phy, 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
