AVIRIS-Classic: Airborne Hyperspectral Radiance Imagery

224 contiguous spectral bands from 400-2500 nm at approximately 10-nm intervals are measured by the AVIRIS-Classic pushbroom sensor. The dataset provides Level 1B orthocorrected radiance image files, along with ancillary files for geometry, illumination, and calibration, collected from aircraft platforms like the Twin Otter and NASA's ER-2. Its 1 milliradian field of view yields ground sampling distances ranging from 20 meters to sub-meter, depending on flight altitude.

Use Cases

• Mineral and soil mapping based on high-resolution spectral signatures across 224 bands.
• Vegetation biochemistry analysis using calibrated radiance in the visible to shortwave infrared range.
• Atmospheric correction algorithm validation based on provided geometry and illumination parameter files.
• Sensor cross-calibration studies based on included radiometric and spectral calibration files.
• High-resolution land cover classification using orthocorrected imagery with sub-meter to 20m ground sampling.

Strengths

• Provides high signal-to-noise ratio (SNR) data designed for high-performance spectroscopy.
• Includes extensive ancillary data like geometric lookup tables, observation geometry, and calibration files for each flight line.
• Spectral resolution is explicitly defined as 224 contiguous bands at ~10-nm intervals from 400-2500 nm.

Limitations

• Key metadata such as row count, column names, and specific file sizes are not provided by any source.
• The listed last update date of '2026-03-13' is a future date, indicating a potential metadata error or placeholder value.
• Documentation gaps exist, as the license is ambiguously listed as 'other-license-specified' without details.
