[Termes IGN] surface forestièreRésumé : (auteur) Aboveground biomass was estimated from active and passive remote sensing sources, including airborne lidar and Landsat-8 satellites, in an eastern Arizona (USA) study area comprised of forest and woodland ecosystems. Compared to field measurements, airborne lidar enabled direct estimation of individual tree height with a slope of 0.98 (R2 = 0.98). At the plot-level, lidar-derived height and intensity metrics provided the most robust estimate for aboveground biomass, producing dominant species-based aboveground models with errors ranging from 4 to 14 Mg ha –1 across all woodland and forest species. Landsat-8 imagery produced dominant species-based aboveground biomass models with errors ranging from 10 to 28 Mg ha –1. Thus, airborne lidar allowed for estimates for fine-scale aboveground biomass mapping with low uncertainty, while Landsat-8 seems best suited for broader spatial scale products such as a national biomass essential climate variable (ECV) based on land cover types for the United States.

[Termes IGN] puits de carboneRésumé : (auteur) Our aim was to investigate the possible enhancing role of long-term atmospheric CO2 increase on wood density as an essential component of biomass sequestration. We therefore assessed the long-term evolution of wood density over pre-industrial and contemporary periods, in a regional context free of management practices, atmospheric deposition and with restricted climatic change. Dominant trees of Araucaria araucana were sampled in 37 stands distributed throughout its natural distribution over temperate forests of the Chilean Andes Cordillera. Mean ring density (MRD) at 1.30 m was measured by X-ray micro-densitometry. A third-century MRD chronology was built after MRD standardisation by the effects of cambial age and radial growth, simultaneously estimated from a statistical model from rings of the pre-industrial period (1700–1850) to avoid any temporal bias. The age-alone standardised MRD chronology showed restricted fluctuations ranging between 2.0 and 3.2 % over the last three centuries. Multi-decennial fluctuations between ring width and MRD were found qualitatively synchronous and opposed. Accordingly, MRD fluctuations were removed with the age and growth standardisation, highlighting the absence of a historical wood density trend at constant ring size over the whole period. Over the most recent decades however, a slight increase in density was identified, with loss of synchronisation to radial growth. The absence of a long-term signal in wood density of A. araucana, in a context of restricted anthropogenic influence, differs markedly from reports of significant decreases in the Northern Hemisphere. We conclude as part of the analysis done that until now, increasing atmospheric CO2 unlikely would have an impact in wood density.

[Termes IGN] surface terrièreRésumé : (auteur) We proposed a new area-based approach to process Lidar point clouds and develop new sets of metrics to improve models dedicated to predict forest parameters. First, we introduced point normalization based on penetration depth below the outer canopy layer to avoid biases introduced by ground normalization and canopy surface heterogeneity during metric computation. Second, we proposed computation of area and volume metrics from canopy surface models computed from both first and last returns to better characterize the 3D plot heterogeneity. The set of proposed metrics were combined with traditional ones, based on point height above ground level, to measure their contribution to models of basal area (BA) and aboveground volume (AGV). The modeling framework included a wide range of forest types, canopy structures and Lidar characteristics. Models were developed for all sites grouped together or separately. In each case, the set of metrics was submitted to a hierarchical clustering process to select the best variables to be included in the models that were further established using a best-subset method. Overall, the introduction of the proposed metrics allowed a reduction in models root mean squared error from − 0.06% to 19.58% according to forest types and target forest parameters. Best improvements were achieved for broadleaved forests, showing the potential of the proposed metrics to efficiently characterize the structure of such porous forest canopies.

[Vedettes matières IGN] Inventaire forestierRésumé : (auteur) Using the classical power function relationship between inverse plot size and sample variance, the method of Lagrangian multipliers was applied to minimize the variance of the sample mean among measurements on sample plots (e.g. volume or basal area per hectare) subject to a fixed total cost with varying plot size and sample size. This results in equations that can be used to determine optimal plot and sample size for a fixed total cost. The method does not require a prior estimate of variance. Optimal point sampling basal area factor can be substituted for plot size if variance and cost functions are available for point sampling. It was determined theoretically that no feasible optimum solution exists if the ratio of the relative change rate in variance to the relative change rate in cost per plot is less than negative one. This occurs because in that case the variance as a function of plot size is being reduced faster than the cost per plot is increasing in relative terms. An example application based on cost and variance functions from the literature found that the optimal surface was quite flat, so that an optimum existed but a rather wide range of plot and sample size combinations were close to optimum for a fixed total cost. In practical terms this means that a wide range of plot sizes would give nearly equal precision for a fixed total cost in this example. This may not be the case for all realistic parameterizations of the cost functions.

[Termes IGN] régressionRésumé : (auteur) LiDAR data has been successfully used to estimate forest parameters such as canopy heights and biomass. Major limitation of LiDAR systems (airborne and spaceborne) arises from their limited spatial coverage. In this study, we present a technique for canopy height mapping using airborne and spaceborne LiDAR data (from the Geoscience Laser Altimeter System (GLAS)). First, canopy heights extracted from both airborne and spaceborne LiDAR were extrapolated from available environmental data. The estimated canopy height maps using Random Forest (RF) regression from airborne or GLAS calibration datasets showed similar precisions (~6 m). To improve the precision of canopy height estimates, regression-kriging was used. Results indicated an improvement in terms of root mean square error (RMSE, from 6.5 to 4.2 m) using the GLAS dataset, and from 5.8 to 1.8 m using the airborne LiDAR dataset. Finally, in order to investigate the impact of the spatial sampling of future LiDAR missions on canopy height estimates precision, six subsets were derived from the initial airborne LiDAR dataset. Results indicated that using the regression-kriging approach a precision of 1.8 m on the canopy height map was achievable with a flight line spacing of 5 km. This precision decreased to 4.8 m for flight line spacing of 50 km.
