BioSCape: AVIRIS-NG L2B Enhanced Surface Reflectance
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.3334/ornldaac/2385
This dataset holds corrected surface reflectance (L2B) from the Airborne Visible / Infrared Imaging Spectrometer-Next Generation (AVIRIS-NG) instrument flown on a NASA Gulfstream III aircraft during the Biodiversity Survey of the Cape (BioSCape) project.
Description
AVIRIS-NG imagery was acquired in October - November 2023 over the Greater Cape Floristic Region (GCFR), South Africa. BioSCape is a multi-agency, NASA-led research project that integrates airborne imaging spectroscopy and lidar with a suite of measurements of biodiversity.
L2B surface reflectance was derived from L1B radiance data in 425 bands, and this enhanced L2B product includes topographic, glint, and bidirectional reflectance distribution function (BRDF) corrections. Data were georeferenced and projected into UTM coordinates. These files hold the original native ancillary information relevant to the image, as well as the ancillary masks used in the creation and parameterization of the topography, glint, and BRDF corrections applied to enhance these image products.
