plant growth are measureable by this method. A very good
correlation between plant height and dry biomass enables the
establishment of biomass calculations at a certain time step by
this measurement technique. Furthermore, the visualization of
the spatial distribution in a high resolution is possible.
For the future, two research approaches should be followed.
First, TLS data could be linked to spectral data, acquired in the
field (Lietal., 2010). Secondly, the usability of Unmanned
Aerial Vehicles (UAV) for rice growth monitoring with laser
scanning might be considered. As Bareth et al. (2011) mention,
the Riegl LMS-Q160, developed for ALS, might be a promising
device.
