Description of the new space time dataset
.SH DESCRIPTION
\fIt.create\fR is used to create space time datasets of
type raster (STRDS), 3D raster (STR3DS) and vector (STVDS).
.PP
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.
.PP
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).
