Default query¶

The following command is the default one, returning standard information like name, mapset, start_time, end_time of each map in the space time dataset

t.rast.list tempmean_monthly
name|mapset|start_time|end_time
2009_01_tempmean|climate_2000_2012|2009-01-01 00:00:00|2009-02-01 00:00:00
2009_02_tempmean|climate_2000_2012|2009-02-01 00:00:00|2009-03-01 00:00:00
....
2012_11_tempmean|climate_2000_2012|2012-11-01 00:00:00|2012-12-01 00:00:00
2012_12_tempmean|climate_2000_2012|2012-12-01 00:00:00|2013-01-01 00:00:00

Add more info¶

The following command let the user to choose the columns to show

t.rast.list tempmean_monthly columns=name,start_time,min,max
name|start_time|min|max
2009_01_tempmean|2009-01-01 00:00:00|-3.380823|7.426054
2009_02_tempmean|2009-02-01 00:00:00|-1.820261|8.006386
...
2009_01_tempmean|2009-01-01 00:00:00|-3.380823|7.426054
2009_02_tempmean|2009-02-01 00:00:00|-1.820261|8.006386

Filtering the result by value¶

In this example the result is filtered showing only the maps with max value major than 24

t.rast.list tempmean_monthly columns=name,start_time,min,max where="max > 24"
name|start_time|min|max
2009_06_tempmean|2009-06-01 00:00:00|15.962669|25.819681
2009_07_tempmean|2009-07-01 00:00:00|15.32852|26.103664
2009_08_tempmean|2009-08-01 00:00:00|16.37995|27.293282
....
2012_06_tempmean|2012-06-01 00:00:00|14.929379|24.000651
2012_07_tempmean|2012-07-01 00:00:00|18.455802|28.794653
2012_08_tempmean|2012-08-01 00:00:00|15.718526|26.151115

Filtering the result by time range¶

In this example the result is filtered showing only the maps which fall into a specified time range (from .. to):

t.rast.list tempmean_monthly columns=name,start_time,min,max \


  where="start_time > ’2009-06-01 00:00:00’ and start_time < ’2012-08-01 00:00:00’"
name|start_time|min|max
2009_06_tempmean|2009-06-01 00:00:00|15.962669|25.819681
2009_07_tempmean|2009-07-01 00:00:00|15.32852|26.103664
2009_08_tempmean|2009-08-01 00:00:00|16.37995|27.293282
....
2012_06_tempmean|2012-06-01 00:00:00|14.929379|24.000651
2012_07_tempmean|2012-07-01 00:00:00|18.455802|28.794653
2012_08_tempmean|2012-08-01 00:00:00|15.718526|26.151115

Filtering the result by selecting recurring timestamps¶

In this example the result is filtered showing only the maps which fall into a specified recurring time range (here one month per year):

t.rast.list Tseasonal_fieldata_garda where="strftime(’%m’, start_time)=’06’"

Using method option¶

Method option is able to show raster in different way. By default cols value is used, the value comma will print only the list of maps inside the space time dataset:

t.rast.list method=comma input=tempmean_monthly
