DESCRIPTION

       List  time  stamped  raster map layers that are registered in a space time raster dataset.
       t.rast.list provides several options to list map layers and their metadata. Listing of map
       layer  can  be  ordered  by  metadata,  metadata  columns  can  be specified and SQL where
       conditions can be provided to select a map layer subset of the  input  space  time  raster
       dataset.  Most  of  the  raster  map   specific metadat is available for column selection,
       sorting and SQL where statements.  Using the method option  allows  the  specification  of
       different  methods  to  list map layers. Method col is the default option and sensitive to
       the column,order and where options.  It will simply print user specified metadata  columns
       of  one  map  layer  per line. The comma method will list the map layer as comma separated
       list that can be used as input for spatial modules.

       To print interval length in days and distance from the  begin  use  method  delta.  Method
       deltagap  will  additionally print temporal gaps between map layer. The gran method allows
       the listing of map layer sampled by a user defined granule. As default the granularity  of
       the  space  time  raster dataset is used for sampling.  The output column separator can be
       specified with the separator option.

EXAMPLES

       This example shows several options that are available for map layers listing.

   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

       The delta value calculate the interval between maps and the distance from the first map:

       The gran value it is used to return data sampled by a user defined granule. As default the
       granularity of the space time raster dataset is used for sampling.
