Results are presented in terms of relative bidirectional reflectance factors (BRFs) as a function of view angle at a number of solar zenith angles, nadir BRFs as a function of solar zenith angles, and, for wheat, vegetation indices as related to view and solar zenith angles. The wheat canopy exhibited the largest BRF changes with view angle. BRFs for the red and the near-infrared (NIR) bands measured over wheat did not have the same

Evaluation and Correction of Viewing Angle Effects on Satellite Measurements of Bidirectional Reflectance
he effects of the angular anisotropy of reflective properties of natural surfaces are studied with an airborne tnultispectral scanner, which allows us to analyze the radiance variations with respect to viewing angle for its f 37' scan angle range and under different illumination conditions. With respect to seven cover-types, the off-nadir effects are significant (mean relative variation of 60 p...
متن کاملDevelopment of a Model to Correct Multi-view Angle above Water Measurements for the Analysis of the Bidirectional Reflectance of Coral and Other Reef Substrates
Spectral reflectance characteristics of substrates in a coral reef environment are often measured in the field by viewing a substrate at nadir. However, viewing a substrate from multiple angles would likely result in different spectral characteristics for most coral reef substrates and provide valuable information on structural properties. To understand the relationship between the morphology o...
متن کاملNormalization of Sun/View Angle Effects Using Spectral Albedo-Based Vegetation Indices
C u r r e n t vegetation indices are normally computed with directional spectral reflectances and are subjected to many external perturbations such as soil background variations, atmospheric conditions, geometric registration, and especially sensor viewing geometry. Subsequent use of these indices to estimate vegetation amounts would result in substantial uncertainties. To reduce the uncertaint...
متن کاملImpact of BRDF on Physics Based Modeling as Applied to Target Detection in Hyperspectral Imagery
Traditional approaches to hyperspectral target detection involve the application of detection algorithms to atmospherically compensated imagery. Rather than compensate the imagery, a more recent approach uses physical models to generate radiance signature spaces. The signature space is actually a representation of what the target might look like to the sensor as the reflectance propagates throu...
متن کاملBidirectional reflectance measurements of sediments in the vicinity of Lee Stocking Island, Bahamas
In situ measurements of bidirectional reflectance factors (REFFs) are presented for submerged carbonate sediments at six sites in the vicinity of Lee Stocking Island. Sediment grain sizes ranged from 400 mm to .1000 mm. Several features were common to all data sets. Although overall sediment reflectance varied spectrally, normalized REFF was independent of wavelength within the natural sample v...
