True surface color from aircraft imaging (2013-2018)

WDTS: AVIRIS-Classic L2B Corrected and Georectified Surface Reflectance, 2013-2018
land NASA ORNL_CLOUD Level 2 multiple
In plain English

What it measures. Detailed maps of the true color of the land surface across hundreds of narrow light bands, from visible into shortwave infrared, covering parts of California and Nevada at about 15-meter detail.

How it's made. Collected by the AVIRIS-Classic imaging spectrometer flown on NASA's high-altitude ER-2 aircraft from 2013 to 2018, then corrected for terrain, sun-angle, and glint effects and aligned to Landsat imagery.

How & where you'd use it. Supports detailed studies of vegetation, soils, and land cover where fine-grained color and material information matters, such as mapping plant diversity.

Official description

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.
