DESCRIPTION

60       t.create  is used to create space time datasets of type raster (STRDS),
61       3D raster (STR3DS) and vector (STVDS).
62
63       Space time datasets represent spatio-temporal fields  in  the  temporal
64       GRASS  framework.  They  are  designed  to  collect  any amount of time
65       stamped maps with time intervals and time instances. The temporal  type
66       of  a  space  time dataset can be absolute (means with a fixed date) or
67       relative (only sequential maps) and must be set during dataset creation
68       along with the name and the description.
69
70       Time  stamped  maps  can registered in and unregistered from space time
71       datasets. The spatio-temporal extent as well as the metadata of a space
72       time dataset is derived from its registered maps. Hence the metadata is
73       dependent from the dataset type (raster, 3D raster, vector).

EXAMPLE

76   Absolute STRDS dataset
77       Create a raster space time datasets
78       t.create type=strds temporaltype=absolute \
79                output=precipitation_monthly \
80                title="Monthly precipitation" \
81                description="Dataset with monthly precipitation"
82
83   Relative STVDS dataset
84       Create a vector space time datasets
85       t.create type=stvds temporaltype=relative \
86                output=precipitation_monthly_30y \
87                title="Monthly precipitation 30 years" \
88                description="Test dataset with monthly average \
89                precipitation in the last 30 year"
