The bidirectional reflection distribution function (BRDF) is a theoretical concept that describes the relationship between a target's irradiance geometry and the viewing angle of the remote sensing system relative to the target. The BRDF can significantly affect the radiometric characteristics of remotely sensed data, particularly when the data are collected off-nadir. In addition to removing radiometric error, an understanding of BRDF can be used as a source of information for calibrating, validating, and increasing reflectance data accuracy. This research collected BRDF data of Smooth Cordgrass (Spartina alterniflora) in South Carolina to document changes in BRDF patterns. A Sandmeier Field Goniometer (SFG) was used to collect hourly canopy spectral reflectance at 76 hemispherical angles. The data were used to create graphic plots that provided a quantitative assessment of BRDF patterns. |
