80
82 t.list lists any dataset that is registered in the temporal database.
83 Datasets are raster, 3D raster and vector maps as well as their corre‐
84 sponding space time datasets (STRDS, STR3DS and STVDS). The type of the
85 dataset can be specified using the type option, default is STRDS. By
86 default all datasets with relative and absolute time are listed. How‐
87 ever, the user has the ability to specify a single temporal type with
88 the temporaltype option. The user can define the columns that should be
89 printed for each dataset and the order of the datasets. In addition a
90 SQL WHERE statement can be specified to select a subset of the re‐
91 quested datasets.
92
94 The SQL where and sort expression will be applied for each temporal
95 database that was found in accessible mapsets. Hence sorting works only
96 on mapset basis.
97 Temporal databases stored in other mapsets can be used as long as they
99 are in the user’s current mapset search path (managed with g.mapsets).

102 Obtain the list of space time raster dataset(s):
103 t.list strds
104 ----------------------------------------------
105 Space time raster datasets with absolute time available in mapset <climate_2000_2012>:
106 tempmean_monthly@climate_2000_2012
107 Obtain the list of space time raster datasets in a specific mapset
108 (Note that the target mapset must be in the user’s search path):
109 # strds in PERMANENT
110 t.list strds where="mapset = ’PERMANENT’"
111 ----------------------------------------------
112 # strds in climate_2000_2012
113 t.list strds where="mapset = ’climate_2000_2012’"
114 ----------------------------------------------
115 Space time raster datasets with absolute time available in mapset <climate_2000_2012>:
116 precip_abs@climate_2000_2012
117 precipitation@climate_2000_2012
118 tempmean@climate_2000_2012
119 The where option can also be used to list the stds with a certain pat‐
120 tern in their name, i.e. as the pattern option in g.list.
121 # strds whose name start with "precip"
122 t.list type=strds where="name LIKE ’precip%’"
123 ----------------------------------------------
124 Space time raster datasets with absolute time available in mapset <climate_1970_2012>:
125 precip_abs@climate_1970_2012
126 precipitation@climate_1970_2012
127 The user can also obtain the list of time stamped raster maps. These
128 maps might be registered in strds or not. The output of the following
129 command can vary according to the accessible mapsets specified through
130 g.mapsets.
131 t.list raster
132 Time stamped raster maps with absolute time available in mapset <climate_2000_2012>:
133 2009_01_tempmean@climate_2000_2012
134 2009_02_tempmean@climate_2000_2012
135 2009_03_tempmean@climate_2000_2012
136 ...
137 2012_10_tempmean@climate_2000_2012
138 2012_11_tempmean@climate_2000_2012
139 2012_12_tempmean@climate_2000_2012
