Abstract
We investigated the use of terrestrial
laser scanner (TLS) range and brightness data for the measurement of seasonal
snow cover. A practical application of a newly developed calibration technique
for laser scanner intensity, based on calibrated reference targets for airborne
and terrestrial use, is demonstrated. We applied this technique in snow
cover measurements, and demonstrate that changes in the snow cover (snow pack
height, changes in grain size/shape and overall wetness) are observable in
terrestrial laser scanner range and brightness data, and call for development
of new TLS-based snow monitoring methods. The role of other factors in the
laser intensity measurement and calibration for snow, such as the incidence
angle of the laser beam to the surface, is also discussed.
