t.remove - Removes space time datasets from temporal database.

       Sören Gebbert, Thünen Institute of Climate-Smart Agriculture

       The module t.remove removes space time datasets (STRDS, STR3DS, STVDS) from  the  temporal  database.  In
       other  words,  by  default  it  deletes  the  relevant database entries. It can also unregister maps from
       temporal database using the recursive mode -r (recursive).

       Optionally, also the raster, 3D raster and vector maps of the space time datasets can be removed from the
       current mapset using the -d (delete) flag.  All removals only work if -f (force) flag is used.

       In this example a space time raster dataset (STRDS) named  precip_months_sum  will  be  created  using  a
       subset of the monthly precipitation raster maps from the North Carolina climate sample data set.
       In  order  to be able to show the case of recursive removal without deleting the original sample data, we
       generate new data by means of computing yearly precipitation sums. Eventually, all  newly  produced  data
       (STRDS and raster maps) are removed:
       # Create new and empty STRDS
       t.create output=precip_months_sum semantictype=mean \
         title="Monthly sum of precipitation" \
         description="Monthly sum of precipitation for the \
         North Carolina sample data"
       # Register maps from sample dataset (selecting a subset with g.list)
       t.register -i type=raster input=precip_months_sum \
         maps=$(g.list type=raster pattern="201*_precip" separator=comma) \
         start="2010-01-01" increment="1 months"
       # Create some new data by aggregating with 1 years granularity
       t.rast.aggregate input=precip_months_sum \
         output=precip_years_sum basename=precip_years_sum \
         granularity="1 years" method=sum
       # Remove all newly produced data:
       # a) the aggregated STRDS with 1 years granularity along with its raster maps
       t.remove -df type=strds input=precip_years_sum
       # b) the STRDS with 1 months granularity, but not the original sample data
       t.remove -f type=strds input=precip_months_sum
