man x2sys_get () - Get track listing from track index databases
NAME
x2sys_get - Get track listing from track index databases
SYNOPSIS
x2sys_get -TTAG [ -Fflags ] [ -Rwest/east/south/north ] [ -S ] [ -V ]
DESCRIPTION
x2sys_get will return the track data files that match the given requirements. You may choose a geographic region and optionally ask only for tracks that meet certain data criteria.
- TAG
- The unique name of this data type system.
OPTIONS
No space between the option flag and the associated arguments
- -F
- Give a comma-separated list of column names as defined in the definition file. [Default is all data columns].
- -R
- xmin, xmax, ymin, and ymax specify the Region of interest. For geographic regions, these limits correspond to west, east, south, and north 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 wesn. The two shorthands -Rg -Rd stand for global domain (0/360 or -180/+180 in longitude respectively, with -90/+90 in latitude). For calendar time coordinates you may either give relative time (relative to the selected TIME_EPOCH and in the selected TIME_UNIT; append t to -JX|x), or absolute time of the form [date]T[clock] (append T to -JX|x). At least one of date and clock must be present; the T is always required. The date string must be of the form [-]yyyy[-mm[-dd]] (Gregorian calendar) or yyyy[-Www[-d]] (ISO week calendar), while the clock string must be of the form hh:mm:ss[.xxx]. The use of delimiters and their type and positions must be as indicated (however, input/output and plotting formats are flexible).
- -S
- Strip off the filename suffix when reporting.
- -V
- Selects verbose mode, which will send progress reports to stderr [Default runs "silently"].
EXAMPLES
To find all the tracks associated with the tag MGD77, restricted to occupy
a certain region in the south Pacific, and have at least free air anomalies
and bathymetry, try
x2sys_get -V -TMGD77 -R180/240/-60/-30 -Ffaa,top
