Palavras-Chave | Biomass modeling forest inventory SAR data tropical forest reforested |
Resumo | This work presents two practical examples of polarimetric and/or interferometric attributes of SAR data to improve the knowledge of structural aspects of forest typologies. At the first, we discuss the important role of polarimetric and interferometric airborne SAR data (OrbiSAR-1 system using bands of XHH and PHH, HV, VH and VV) for the aboveground biomass estimation of Eucalyptus sp. Stands, to subsidize the operational forest management activities for the production of cellulose. This study area is reforested with Eucalyptus saligna (aged 6 years, with an average height of 23 m) and also with clonal stands of E. Grandis e E. Urophylla (aged 2,3 years, with an average height of 14 m). The second is a contribution of polarimetric attributes of ALOS/PALSAR (L-band) for aboveground biomass modeling of primary and secondary forest from Amazonia (Tapajós region, Pará State). To perform both studies, we carried out multivariable regression techniques, using variables obtained from SAR attributes and biophysical parameters collected during field surveys, which were done simultaneously to SAR imaging campaign. All SAR data from each mission were calibrated both radiometrically and geometrically to extract information during the digital processing. In summary the results were: (a) the variables combination of Interferometry Height - HInt 2 (derived from the difference between interferometric digital elevation model in X- and P- bands) and Canopy Scattering Index - CSI (ratioof °VV by the sum of °VV and °HH, which represents the canopy interaction) are important in this Eucalyptus biomass model; (b) the most significant variables for tropical forest biomass modeling were the °HH coefficient, the volume scattering component of Freemans decomposition, the Touzis magnitude of the second component, the phase of the second and third components and the heliticity mean angle. Aiming to validate the results obtained by the models, a set of independent data from the forest inventory were generated, which indicated a prediction average error of 10% to estimate the Eucalyptus biomass and below 20% to the tropical forest. These results obtained in the reforested areas and tropical forests show the importance of combining several SAR attributes, focusing on models of forest stock density. |
