## 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
