- Abstract
- This paper addresses the use of the bidirectional reflectance distribution function
(BRDF) of natural surfaces for remote sensing applications and environmental
monitoring. Multiangle images, acquired by the compact high resolution imaging
spectrometer (CHRIS) over the San Rossore test site, have been analysed in
order to exploit the potential of using the BRDF for data mining and precise
retrieval of biophysical and geophysical parameters. The apparent reflectance
and the anisotropy factor (ANIF) of selected soil cover types have been
computed, after correcting the at-sensor radiance for atmospheric effects. The
departure of soil reflectance from the standard Lambertian behaviour has been
investigated, together with the hypothesis of BRDF spectral-angular separability.
Then, the ANIF dependence on surface optical properties, illumination and
viewing geometry has been assessed and demonstrated using an ANIF image.
The stability of the atmospheric correction procedure was analysed, studying the
retrieved reflectance versus the solar zenith angle.
