Default: strds
DESCRIPTION
t.info reports information about any dataset that is registered in the
temporal database in human readable or shell script style. Datasets are
raster, 3D raster and vector maps as well as their corresponding space
time datasets (STRDS, STR3DS and STVDS). This module reports the infor-
mation that are stored in the temporal database. These are basic infor-
mation (id, name, mapset, creator, creation time, temporal type), the
temporal and spatial extent and dataset type specific metadata. The
user has to utilize r.info, r3.info, v.info to report detailed informa-
tion about raster, 3D raster and vector maps, since not all map spe-
cific information and metadata are stored in the temporal database.
In addition, information about the chosen temporal database backend can
be reported.
NOTES
Temporal databases stored in other mapsets can be used as long as they
are in the user’s current mapset search path (managed with g.mapsets).
EXAMPLES

| Title:
| Monthly precipitation
| Description:
| Dataset with monthly precipitation
| Command history:
| # 2014-11-27 08:50:48
| t.create type="strds" temporaltype="absolute"
| output="tempmean_monthly" title="Monthly precipitation"
| description="Dataset with monthly precipitation"
| # 2014-11-27 09:44:32
| t.register -i type="rast" input="tempmean_monthly" maps="2009_01_tempmean,...,2012_12_tempmean" start="2009-01-01" increment="1 months"

+----------------------------------------------------------------------------+
The "granularity" is the smallest gap size between the found time in-
stances, i.e. it the greatest common divisor between all gaps in the
time series.
