SHIFT AVIRIS-NG High-Resolution True Color Airborne Imagery

NASA's SHIFT campaign provides full-resolution true color imagery from the AVIRIS-NG airborne spectrometer. The dataset contains images collected at approximately weekly intervals from February to May 2022, with a follow-up in September 2022, across a broad study area. Each flight line includes both a PNG for visualization and a georeferenced, cloud-optimized GeoTIFF containing floating-point radiance values.

Use Cases

• Analyzing seasonal vegetation changes using high-resolution (2-5 m) true color imagery from specific wavelengths (808, 658, 563 nm).
• Validating surface reflectance models with calibrated radiance data stored in the GeoTIFF files.
• Studying traceability of VSWIR spectral revisits for future satellite mission planning.
• Conducting land cover classification and change detection using georeferenced, time-series airborne imagery.

Strengths

• Data has high signal-to-noise ratio and spectral fidelity, measured at 5-nm intervals from 380-2510 nm.
• Imagery offers fine spatial resolution, generally finer than 5 meters and down to 2 meters depending on the flight line.
• Provides a high-frequency time series with approximately weekly cadence during the primary campaign.

Limitations

• Specific column names, row counts, and total dataset size are not provided by any source.
• Sources conflict on the last update date: one states 2026-03-12, another states 2022-05, suggesting potential metadata inconsistency.
