abstract = "The presence of atmosphere with aerosols and gases alters the
reflected signal from the surface, resulting in a decrease in the
quality of the hyperspectral image. The assessment of this data
requires that these atmospheric effects be removed from the
imagery, to retrieve the inherent spectral reflectance of the
surface materials, in a process referred to as atmospheric
correction. This work examines the use of hyperspectral remote
sensing techniques to compare the equivalence of three atmospheric
correction methods (Green, FLAASH and QUAC) using two spectral
indices that test different regions of the spectrum, around the
visible (PSRI) and in the short-wave infrared (CAI), in order to
evaluate the hyperspectral reflectance of the Cerrado vegetation
canopy. The imagery of the study site was collected by a AVIRIS
sensor in august 1996, and refers to a scene from the municipality
of S{\~a}o Jo{\~a}o da Alian{\c{c}}a, State of Goi{\'a}s,
Brazil. The obtained resultant images, corrected using both FLAASH
and QUAC atmospheric correction algorithms, were compared with the
image corrected using the Green method. FLAASH is found to be a
better match for Cerrado vegetation samples analysis. The spectral
absorption bands in the visible region of the spectrum, tested
with the PSRI vegetation index, have found a better equivalence in
between the three atmospheric correction methods.",
