DESCRIPTION

53       The  module t.remove removes space time datasets (STRDS, STR3DS, STVDS)
54       from the temporal database. In other words, by default it  deletes  the
55       relevant  database  entries.  It can also unregister maps from temporal
56       database using the recursive mode -r (recursive)
57
58       Optionally, also the raster, 3D raster and vector  maps  of  the  space
59       time  datasets  can  be  removed  from  the current mapset using the -d
60       (delete) flag.  All removals only work if -f (force) flag is used.

EXAMPLE

63       In this  example  a  space  time  raster  dataset  (STRDS)  named  pre‐
64       cip_months_sum will be created using a subset of the monthly precipita‐
65       tion raster maps from the North Carolina climate sample data set.
66       In order to be able to show  the  case  of  recursive  removal  without
67       deleting  the  original  sample  data, we generate new data by means of
68       computing yearly precipitation sums.  Eventually,  all  newly  produced
69       data (STRDS and raster maps) are removed:
70       #Create new and empty STRDS
71       t.create output=precip_months_sum semantictype=mean \
72         title="Monthly sum of precipitation" \
73         description="Monthly sum of precipitation for the \
74         North Carolina sample data location"
75       #Register maps from sample dataset (selecting a subset with g.list)
76       t.register -i type=raster input=precip_months_sum \
77         maps=$(g.list type=raster pattern="201*_precip" separator=comma) \
78         start="2010-01-01" increment="1 months"
79       #Create some new data by aggregating with 1 years granularity
80       t.rast.aggregate input=precip_months_sum \
81         output=precip_years_sum basename=precip_years_sum granularity="1 \
82         years" method=sum
83       #Remove all newly produced data:
84       # a) the aggregated STRDS with 1 years granularity along with its raster maps
85       t.remove -df type=strds input=precip_years_sum
86       # b) the STRDS with 1 months granularity, but not the original sample data
87       t.remove -f type=strds input=precip_months_sum
