Columns number_of_maps and granularity only available for space time datasets
Options: id, name, creator, mapset, number_of_maps, creation_time, start_time,
end_time, interval, north, south, west, east, granularity
Default: id

columns=string[,string,...]
Columns to be printed to stdout
Columns number_of_maps and granularity only available for space time datasets
Options: id, name, creator, mapset, number_of_maps, creation_time, start_time,
end_time, north, south, west, east, granularity, all
Default: id

where=sql_query
WHERE conditions of SQL statement without ’where’ keyword used in the temporal GIS
framework
Example: start_time > ’2001-01-01 12:30:00’

separator=character
Field separator character between the output columns
Special characters: pipe, comma, space, tab, newline

DESCRIPTION

t.list lists any dataset that is registered in the temporal database. Datasets are raster,
3D raster and vector maps as well as their corresponding space time datasets (STRDS,
STR3DS and STVDS). The type of the dataset can be specified using the type option, default
is STRDS. By default all datasets with relative and absolute time are listed. However, the
user has the ability to specify a single temporal type with the temporaltype option. The
user can define the columns that should be printed for each dataset and the order of the
datasets. In addition a SQL WHERE statement can be specified to select a subset of the
requested datasets.

NOTES

The SQL where and sort expression will be applied for each temporal database that was
found in accessible mapsets. Hence sorting works only on mapset basis.

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

Obtain the list of raster space time dataset(s):
t.list strds
----------------------------------------------
Space time raster datasets with absolute time available in mapset climate_2000_2012:
tempmean_monthly@climate_2000_2012
The user can obtain also the list of raster maps contained in a temporal datasets (this
may be the content of several space time datasets if enabled through g.mapsets):
t.list raster
Time stamped raster maps with absolute time available in mapset climate_2000_2012:
2009_01_tempmean@climate_2000_2012
2009_02_tempmean@climate_2000_2012
2009_03_tempmean@climate_2000_2012
...
2012_10_tempmean@climate_2000_2012
2012_11_tempmean@climate_2000_2012
2012_12_tempmean@climate_2000_2012
