Forest Canopy Gap Fraction From Terrestrial Laser Scanning [PDF]
IEEE Geoscience and Remote Sensing Letters, 2007 A terrestrial laser scanner (TLS) was used to measure\ud canopy directional gap fraction distribution in forest stands\ud in the Swiss National Park, eastern Switzerland. A scanner model\ud was derived to determine the expected number of laser shots in\ud all directions, and these data were compared with the measured\ud number of laser hits to ...

Glacier Snowline Determination from Terrestrial Laser Scanning Intensity Data [PDF]
Geosciences, 2017 Accurately identifying the extent of surface snow cover on glaciers is important for extrapolating end of year mass balance measurements, constraining the glacier surface radiative energy balance and evaluating model simulations of snow cover. Here, we use auxiliary information from Riegl VZ-6000 Terrestrial Laser Scanner (TLS) return signals to ...
