abstract = "Hyperspectral remote sensing allows to obtain information about a
target in the natural environment in different regions of the
spectrum, which allows a wide range of data on its situation, and
it is possible to extract the spectral features of reflectance /
absorption that identify the composition of the materials in
pictures. There are several methods to perform the atmospheric
correction in hyperspectral data. The objective of this study was
to verify the influence of the atmospheric correction on exposed
soil of the municipality of S{\~a}o Jo{\~a}o dAlian{\c{c}}a,
Goi{\'a}s, using the NDBSI spectral index in AVIRIS images. To
determine the influence of the atmospheric correction of the
images processed by FLAASH and QUAC, including the uncorrected
radiance image, the NDBSI index applied to the soils of the study
area was used. Then, Pearson correlation coefficients were
determined. The highest correlation between the radiance data and
the atmospheric correction algorithms was for the FLAASH method,
followed by the QUAC. Changes were observed in the inclination of
the curves related to the spatial variation of the targets along
the transect in the image. Intermediate values are related to
areas of partially exposed soil, or partially covered. Although
the curve of the QUAC method is closer to that of radiance, the
FLAASH values are more correlated. The FLAASH method showed a
slightly superior performance to the QUAC, since the data had a
highly linear relationship with the radiance data in determining
the NDBSI index.",
