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...
متن کاملAnalysis of Extracting Prior BRDF from MODIS BRDF Data
Many previous studies have attempted to extract prior reflectance anisotropy knowledge from the historical MODIS Bidirectional Reflectance Distribution Function (BRDF) product based on land cover or Normalized Difference Vegetation Index (NDVI) data. In this study, the feasibility of the method is discussed based on MODIS data and archetypal BRDFs. The BRDF is simplified into six archetypal BRD...
متن کاملEstimating Canopy Height of Montane Cool Temperate Forest Using Large-footprint Spaceborne Lidar
Estimation of forest carbon storage is a critical challenge for understanding the global carbon cycle because it dominates the dynamics of the terrestrial carbon cycle. Light Detection and Ranging (LiDAR) system has a unique capability for estimating accurately forest canopy height, which has a direct relationship and can provide better understood to the aboveground carbon storage. To test the ...

متن کاملEstimation of vegetation clumping index using MODIS BRDF data
The foliage clumping index quantifies the degree of the deviation of leaf spatial distribution in the canopy from the random case. It is of comparable importance for ecological models as the leaf area index for quantifying radiation interception and distribution in plant canopies. Previously, an improved angular index named normalized difference between hotspot and darkspot was proposed for ret...
