 locations in a space time raster dataset over a period of time using
 vector points.
 
+The first input is a vector map layer with vector points. The second 
+input is one or several space time raster datasets (STRDS) that should 
+be sampled over time at the vector point positions. The space time 
+raster dataset will be sampled over its whole temporal extent (from 
+start to end). The range can be adjusted using the temporal where 
+condition <em>t_where</em>. A column name must be specified for each 
+input space time raster dataset.
+<p>
+As results  a new space time vector dataset is generated that contains 
+a single (new) vector map that links to as many time stamped attribute 
+tables as raster map layer are present in the input space time raster 
+dataset. Hence, for each time step in the space time raster dataset a 
+new attribute table is created. The GRASS GIS Temporal Framework allows 
+to time stamp attribute tables that can be linked to a single vector 
+map layer.
+<p>
+The module <em>v.what.rast</em> is used internally for sampling the 
+time stamped raster map layers. All sampled values of a single time 
+stamped raster map layer are written into a new time stamped attribute 
+table.
+<p>
+Use <em>t.vect.db.select</em> to print attribute values of the space
+time vector dataset to stdout.
