ABoVE: AVIRIS-NG Airborne Spectroscopy for Arctic Regions, 2017-2022

AVIRIS-NG airborne imaging spectroscopy data covering approximately 120,000 km2 across Alaska, Canada, and Iceland from 2017 to 2022. The dataset comprises roughly 1700 flight lines with a 5-meter spatial resolution, measuring reflected radiance in 425 spectral bands from 380 to 2510 nm. It was collected by NASA as part of the ABoVE multi-sensor campaign and is provided in ENVI format with RGB composites and shapefiles.

Use Cases

• Classifying land cover and vegetation types based on high-resolution spectral reflectance data.
• Monitoring changes in the tundra-taiga ecotone gradient based on transect sampling.
• Analyzing surface properties in key study areas like the Mackenzie Delta or CHARS Greiner watershed.
• Developing spectral indices for environmental monitoring using 425 bands of calibrated data.

Strengths

• Covers approximately 120,000 km2 with a nominal spatial resolution of 5 meters.
• Includes ~1700 individual flight lines providing extensive spatial sampling.
• Data is radiometrically and geometrically calibrated, and supersedes previous versions.
• Spectral measurements across 425 bands at 5-nm intervals from 380 to 2510 nm.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
