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"
