WDTS: AVIRIS-Classic L2B Corrected and Georectified Surface Reflectance, 2013-2018

This dataset includes Level-2 (L2) surface reflectance imagery from the AVIRIS-Classic instrument collected for NASA's Western Diversity Time Series Project over California and Nevada in 2013 to 2018. AVIRIS-Classic imagery were collected on the NASA ER-2 from altitude of 19,800 m, yielding imagery with 15-20 m ground sample distance. AVIRIS-Classic is a 224-channel whisk-broom instrument with four grating imaging spectrometers covering a spectral range from 400-2500 nm, with spectral sampling every 10 nm. Radiometric calibration accuracy is within 1 nm, and signal to noise ratio is greater than 100:1. Existing L2 imagery were reprocessed co-register pixels with cloud-free panchromatic imagery from Landsat. Then, topographic, FlexBRDF, and glint corrections were applied and the georectified images were resampled to 15-m spatial resolution. The imagery data are provided in ENVI format. Ground control points used in georectification along the BRDF and topographic correction coefficients are provided in JSON files.
