<h2>DESCRIPTION</h2>
<em>t.create</em> is used to create space time datasets of
type raster (STRDS), 3D raster (STR3DS) and vector (STVDS).
<p>
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.
<p>
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).
<h2>EXAMPLE</h2>
<h3>Absolute STRDS dataset</h3>
Create a raster space time datasets
<div class="code"><pre>
t.create type=strds temporaltype=absolute \
output=precipitation_monthly \
title="Monthly precipitation" \
description="Dataset with monthly precipitation"
</pre></div>
<h3>Relative STVDS dataset</h3>
Create a vector space time datasets
<div class="code"><pre>
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"
</pre></div>
