X and P band SAR images from the airborne OrbiSAR-1 sensor, were acquired at the study area in the southeast region of Brazil. The interferometric height (Hint = difference between interferometric digital elevation model in X and P bands), contributed to the models developed due to fact that Eucalyptus forest is composed of individuals whose structure is predominantly cylindrical and vertically oriented, and whose tree heights have great correlation with volume and biomass. The volume model showed that the stand volume was highly correlated with the interferometric height logarithm (Log10Hint), since Eucalyptus tree volume has a linear relationship with the vegetation height. The biomass model showed that the combination of both Hint2 and Canopy Scattering Index\u2014CSI (relation of s\u00b0VV by the sum of s\u00b0VV and s\u00b0HH, which represents to the canopy interaction) were used in this model, due to the fact that the Eucalyptus biomass and the trees height relationship is not linear. Both models showed a prediction error of around 10% to estimate the Eucalyptus biomass and volume, which represents a great potential to use this kind of technology to help establish Eucalyptus forest inventory for large areas.<\/jats:p>","DOI":"10.3390\/rs2040939","type":"journal-article","created":{"date-parts":[[2010,3,31]],"date-time":"2010-03-31T11:10:34Z","timestamp":1270033834000},"page":"939-956","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":68,"title":["Eucalyptus Biomass and Volume Estimation Using Interferometric and Polarimetric SAR Data"],"prefix":"10.3390","volume":"2","author":[{"given":"F\u00e1bio Furlan","family":"Gama","sequence":"first","affiliation":[{"name":"National Institute for Space Research-INPE, Av. dos Astronautas, 1758, P.O.
