In this paper we present a study on the estimation of the aboveground biomass in tropical forests at single tree level using airborne laser scanning (ALS) data. Individual tree crowns (ITCs) are firstly detected using a method based on an adaptive window that change its size according to tree height. The diameter at breast height (DBH) and the aboveground biomass (AGB) of each ITC then are predicted...
Above-ground tree biomass was estimated for the low-land forests of Taman Negara, Pahang. Five transect lines measuring at 100 × 20 m of each were established for this study. The transect lines consist of a total of 439 trees. The tree height and the diameter at breast height (DBH) of all trees (≥ 10 cm) were measured in each transect line. Kato et al. (1978) function was used to estimate the three...
The goal of this study is to show the potential of a compact-pol SAR system for vegetation applications. Compact-pol concept has been suggested to minimize the system design while maximize the information and is declined as the π/4, π/2 and hybrid modes. In this paper, the applications such as classification, Faraday rotation and soil moisture estimates are first reminded, then, biomass estimation...
Global warming is now known to be the major environmental issue mankind will have to face in the next decade. Monitoring of vegetation and biomass is clearly an essential piece of information required at all levels ranging from the scientific studies to understand and forecast, to the political actors and government leaders responsible for drafting remediation policies and evaluating their impact...
