Estimation of LAI and fractional cover from small footprint airborne laser scanning data based on gap fraction
Abstract We evaluate the potential of deriving fractional cover (fCover) and leaf area index (LAI) from discrete return, small footprint airborne laser scanning (ALS) data. fCover was computed as theExpand

Forest Canopy Gap Fraction From Terrestrial Laser Scanning
TLDR
A terrestrial laser scanner (TLS) was used to measure canopy directional gap fraction distribution in forest stands in the Swiss National Park, eastern Switzerland. Expand

Multi-source land cover classification for forest fire management based on imaging spectrometry and LiDAR data
Abstract Forest fire management practices are highly dependent on the proper monitoring of the spatial distribution of the natural and man-made fuel complexes at landscape level. Spatial patterns ofExpand

Wildfire history and fire ecology of the Swiss National Park (Central Alps): new evidence from charcoal, pollen and plant macrofossils
Microscopic (> 10 mm) and macroscopic (> 200 mm) charcoal particles were analysed in sediments from two mires in subalpine coniferous forests at c. 1800 m a.s.l. in southeastern Switzerland. PollenExpand

Fusion of imaging spectrometer and LIDAR data over combined radiative transfer models for forest canopy characterization
A comprehensive canopy characterization of forests is derived from the combined remote sensing signal of imaging spectrometry and large footprint LIDAR. The inversion of two linked physically basedExpand

CLUSTERING IN AIRBORNE LASER SCANNING RAW DATA FOR SEGMENTATION OF SINGLE TREES
TLDR
We explore the potential of delineating single trees from laser scanner raw data (x,y,ztriples) through cluster analysis and validate this approach with a dataset of about 2000 georeferenced trees. Expand

Discrimination of vegetation strata in a multi-layered Mediterranean forest ecosystem using height and intensity information derived from airborne laser scanning
Height and intensity information derived from Airborne Laser Scanning (ALS) was used to obtain a quantitative vertical stratification of vegetation in a multi-layered Mediterranean ecosystem. A newExpand

Assessment of the hazard potential of ice avalanches using remote sensing and GIS‐modelling
Ice avalanches typically occur when a large mass of ice breaks off from steep glaciers. Since the reach of ice avalanches is usually low, their hazard potential is generally restricted to highExpand

Assessment of the influence of flying altitude and scan angle on biophysical vegetation products derived from airborne laser scanning
Airborne Laser Scanning (ALS) has been established as a valuable tool for the estimation of biophysical vegetation properties such as tree height, crown width, fractional cover and leaf area indexExpand
