[Termes IGN] ventRésumé : (Auteur) This paper presents a method to estimate forest parameter and surface topography from NASA's Geosciences Laser Altimeter System (glas). Their potential use as observational inputs to models is demonstrated using a wind-risk model for the UK, ForestGALES. Relative heights above ground were used as biophysical parameter estimators. Top Height was estimated with R2 = 0.73, RMSE = 4.5 m. Diameter at breast height estimates differed for conifer-dominated stands (R2 = 0.72, RMSE = 0.07 m) and for stands containing mostly broadleaves (R2 = 0.41, RMSE = 0.11 m). Ground elevation estimation produced R2 = 0.997, RMSE = 2.2 m. These three parameters were applied to ForestGALES for stand-level assessment of wind-throw risk. Stability is sensitive to small differences in tree dimensions, and therefore vegetation parameters require greater accuracy than those currently retrievable from GLAS to more reliably determine risk of wind-throw. Future satellite lidar mission such as NASA's DESDynl sensor aim to produce improved vegetation parameter estimation plus greater spatial cover-age which would offer more appropriate inputs for forestry models.

Estimating vegetation height within large-footprint Light Detection and Ranging (LiDAR) waveforms relies on the ability to estimate the uppermost canopy surface (signal beginning) and an elevation representing the ground surface, both of which are influenced by vegetation properties and topographic slope. We examined sources of uncertainty for vegetation height estimation from ICESat/GLAS data using airborne LiDAR data, field measurements and the FLIGHT radiative transfer model. In comparison with an independent 10-m resolution digital terrain model (DTM), a method using Gaussian decomposition of the satellite waveform produced a mean bias of -0.10 m when estimating ground elevation. A second method of estimating vegetation height using waveform extent and a terrain index effectively removed slope as an error source but produced a greater ground surface offset (-0.83 m). The two methods of estimating vegetation height compared well with airborne LiDAR estimates (correlation coefficient (R2) = 0.68, root mean square error (RMSE) = 4.4 m and R2 = 0.61, RMSE = 4.9 m, respectively). However, the complex interplay of the structural and optical properties of the intercepted vegetation and slope requires further understanding. A tool such as FLIGHT provides a useful means to explore the sensitivity of the waveform to both vegetation properties and topographic slope.
