Estimation of stem volume using laser scanning-based canopy height metrics

Estimating Forest Canopy Height using Photon-counting Laser Altimetry

Reliable global estimates of forest biomass and its dynamics are critically important for understanding the global carbon cycle and its dynamics (e.g., Bellassen et al. 2011). Many studies have been published regarding the estimation of above-ground biomass using airborne or satellite analog lidar systems (e.g., Nelson et al. 1988; Naesset 2002; Drake et al. 2003; Popescu et al. 2003; Lim and T...

Canopy Extraction Using Airborne Laser Scanning Data in Forestry Areas

To understand the biomass condition in the forestry areas, the detection for individual trees becomes an important topic. For forestry management, the canopy may be described with several parameters, e.g., number of stems, stand position, tree height, timber volume, canopy cover, etc. Traditional methods rely on field measurements, imagery, and radar data to derive the canopy information. Follo...

Effects of Flight Altitude on Tree Height Estimation Using Airborne Laser Scanning

High-density airborne laser scanner data has been previously shown to provide great opportunities for individual tree detection and measurement of variables characterizing the detected trees. This paper evaluates the effect of laser flight altitude on the tree height estimation at individual tree level in the boreal forest area mainly consisting of Norway spruce, Scots pine and birch. The test ...
