Worldview-2 spectral imagery acquired over Duck, NC and Pendleton, CA were analyzed to extract Bidirectional Reflectance Distribution Functions (BRDF) for 8 spectral bands. Spectral data in the visible and near-infrared bands were acquired for 15 azimuth/elevation values during the Duck NC orbit pass; data were collected at ten-second intervals. Ten images were acquired over Pendleton. Orthoready images were coregistered using first-order polynomials for the two image sequences. BRDF profiles have been created for scene elements: vegetation, asphalt, sand, and water. These data allowed for unique high-spatial resolution BRDF profiles, which can be used to inform terrain classification and target detection in satellite imagery.
