6 gmtlegs - Find cruises in a given region
7
9 gmtlegs -Rwest/east/south/north[r] [ -G ] [ -M ] [ -T ] [ -L ] [ -V ]
10
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
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"].
