DESCRIPTION

       t.create is used to create space time datasets of type raster (STRDS), 3D raster  (STR3DS)
       and vector (STVDS).

       Space time datasets represent spatio-temporal fields in the temporal GRASS framework. They
       are designed to collect any amount of time stamped  maps  with  time  intervals  and  time
       instances.  The  temporal type of a space time dataset can be absolute (means with a fixed
       date) or relative (only sequential maps) and must be set  during  dataset  creation  along
       with the name and the description.

       Time  stamped  maps  can  registered  in  and  unregistered  from space time datasets. The
       spatio-temporal extent as well as the metadata of a space time dataset is derived from its
       registered maps. Hence the metadata is dependent from the dataset type (raster, 3D raster,
       vector).

EXAMPLE

   Absolute STRDS dataset
       Create a raster space time datasets
       t.create type=strds temporaltype=absolute \
                output=precipitation_monthly \
                title="Monthly precipitation" \
                description="Dataset with monthly precipitation"

   Relative STVDS dataset
       Create a vector space time datasets
       t.create type=stvds temporaltype=relative \
                output=precipitation_monthly_30y \
                title="Monthly precipitation 30 years" \
                description="Test dataset with monthly average \
                precipitation in the last 30 year"
