USING INDIVIDUAL TREE CROWN APPROACH FOR FOREST VOLUME EXTRACTION WITH AERIAL IMAGES AND LASER POINT CLOUDS
Individual Tree Crown (ITC) Laser scanning Tree height Aerial imagery Segmentation
2015/8/13
The objective of this paper is to improve the cost-effectiveness (accuracy of estimates versus applied costs) of present ITC
(Individual Tree Crown) approaches which are based on 1) aerial imagery or...
APPLICABILITY OF FIRST PULSE DERIVED DIGITAL TERRAIN MODELS FOR BOREAL FOREST STUDIES
DTM quality first pulse last pulse laser scanning TIN grid
2015/8/13
Detailed high-resolution digital terrain models (DTM) can be obtained using airborne laser scanner data. This paper evaluates the
accuracy of DTM derived from first return of laser scanner data for f...
Sensitivity Analysis of Spectral Indices to Ozone Absorption Using Physical Simulations in a Forest Environment: Comparative Study between MODIS, SPOT VéGéTATION & AVHRR
Spectral Indices Ozone Absorption Using Physical Simulations
2015/7/29
Considering a forest cover (Balsam Fir with various densities) we analyze the sensitivity of several vegetation indices to
ozone absorption using physical simulations in the spectral bands of MODIS,...
Modelling longwave radiation to snow beneath forest canopies using hemispherical photography or linear regression
forest snow canopy radiation modelling longwave radiation hemispherical photography
2014/4/3
Forest canopies reduce shortwave radiation and increase longwave radiation reaching the underlying surface, compared with
open areas, and thus influence rates at which forest snowpacks melt. Th...

Wavelet Analysis of the Wind Velocity and Temperature Variability in the Amazon Forest
Intermittence Temperature Wind Turbulence Amazonia Statistical Analysis
2010/10/13
We studied the turbulent interactions among vertical wind velocity and temperature time-series measured in
the Amazonian forest, during the wet season campaign of Large Biophere-Atmosphere Experiment...
Spatial Variability and Cesium-137 Inventories in Native Forest
Spatial Variability Cesium-137 Inventories Native Forest
2010/10/25
With the nuclear fission discovery and development of nuclear weapons in 1940s, artificial radioisotopes were introduced in the environment. This contamination is due to worldwide fallout by superfici...
