NAME

6       gmtlegs - Find cruises in a given region
7

SYNOPSIS

9       gmtlegs -Rwest/east/south/north[r] [ -G ] [ -M ] [ -T ] [ -L ] [ -V ]
10

DESCRIPTION

12       gmtlegs  will  report  the  name of all the cruises that happened to be
13       wholly or partially inside the specified region.  As  an  option,  only
14       those cruises that collected a certain type of data can be reported.
15
16       -R     west, east, south, and north specify the Region of interest, and
17              you   may   specify   them   in   decimal    degrees    or    in
18              [+-]dd:mm[:ss.xxx][W|E|S|N]  format.  Append r if lower left and
19              upper right map coordinates are given instead of  w/e/s/n.   The
20              two  shorthands  -Rg  and -Rd stand for global domain (0/360 and
21              -180/+180 in longitude respectively, with -90/+90 in latitude).
22

OPTIONS

24       No space between the option flag and the associated arguments
25
26       -G     Report cruises that collected  Gravity  data.  [Default  is  any
27              data].
28
29       -M     Report cruises that collected Magnetics. [Default is any data].
30
31       -T     Report cruises that collected Topography. [Default is any data].
32
33       -L     Long output, i.e. cruisenames and data types available. [Default
34              is cruisenames only].
35
36       -V     Selects verbose mode, which will send progress reports to stderr
37              [Default runs "silently"].

EXAMPLES

40       To  find  all cruises around Hawaii that collected gravity and topogra‐
41       phy:
42
43       gmtlegs -R-162/-152/18/25 -G -T > hawaii_gt.legs
44
45       To find all cruises with magnetics:
46
47       gmtlegs -R0/360/-90/90 -M > all_m.legs
