The module t.vect.what.strds samples a space time raster dataset
at spatio-temporal locations of a space time vector dataset.
EXAMPLE
The example is based on the space time vector dataset "precip_stations@climate_2009_2012"
created in the t.vect.observe.strds example.
In below example the command fills the new column "new_temp" with values
extracted from the "tempmean_monthly" space time raster dataset:
