“…It is worth noting that the quality of the DEM strongly depends on the point density, especially in closed-canopy forests (Reutebuch et al 2003). The flexibility of airborne LiDAR, coupled with a high level of positional accuracy and point density, makes airborne LiDAR systems an attractive data acquisition tool for estimating a wide range of tree and forest parameters (Laes et al 2011) such as tree height (Andersen et al 2006;Detto et al 2013), stem volume (Heurich and Thoma 2008), tree biomass (Li et al 2008), and leaf area index (Morsdorf et al 2006). The use of airborne LiDAR for estimating forest inventory parameters and structural characteristics is reviewed by van Leeuwen and Nieuwenhuis (2010), and a meta-analysis of 70 articles has been conducted by Zolkos et al (2013).…”

“…A digital terrain model was calculated for the entire watershed. All returns in the LiDAR point cloud were filtered to identify ground returns using an iterative algorithm (Kraus and Pfeifer 1998;Andersen et al 2006) that computed an initial surface using the weighted average of all LiDAR returns. A cell size of 8 m  8 m was chosen for the initial and intermediate surfaces to provide a sufficient number of ground points within each cell given the moderate density of the LiDAR data and the dense canopy present at many plot sites.…”

“…The focused and narrow laser beam used by LiDAR sensors has a strong penetration capability in forest areas (Lim et al 2003;Jensen 2009;Su and Guo 2014). It has been well documented that LiDAR data can be used to derive highly reliable forest structure parameters such as tree height (Nilsson 1996;Andersen et al 2006;Su et al 2015), canopy cover (Lim et al 2003;Korhonen et al 2011), leaf area index (Riaño et al 2004;Jensen et al 2008), stand volume (Nilsson 1996;Naesset 1997), and tree diameter (Popescu 2007;Huang et al 2011). The capacity to resolve forest structure parameters provides a great opportunity for developing vegetation-mapping strategies (Kramer et al 2014).…”
