abstract = "This work aims to verify the applicability of models obtained
using interferometric synthetic aperture radar (SAR) data for
estimation of biophysical Eucalyptus saligna parameters [diameter
of breast height (DBH), total height and volume], as a method of
continuous forest inventory. In order to obtain different digital
elevation models, and the interferometric height (Hint) to
retrieve the tree heights, SAR surveying was carried out by an
airborne interferometric SAR in two frequencies X and P bands. The
study area, located in the Brazilian southeast region (S
22°53\′22\″/W 45°26\′16\″ and S
22°53\′22\″/W 45°26\′16\″), comprises
128.64 hectares of Eucalyptus saligna stands. The methodological
procedures encompassed: forest inventory, topographic surveying,
radar mapping, radar processing, and multivariable regression
techniques to build Eucalyptus volume, DBH, and height models. The
statistical regression pointed out Hint and interferometric
coherence as the most important variables for the total height and
DBH estimation; for the volume model, however, only the Hint
variable was selected. The performance of the biophysical models
from the second campaign, two years later (2006), were consistent
and its results are very promising for updating annual inventories
needed for managing Eucalyptus plantations.",
