SHIFT Vegetation Plot Data for NASA AVIRIS-NG Calibration

NASA's SHIFT campaign provides ground-truth vegetation data collected weekly from February to September 2022 across three California coastal reserves. This dataset includes plot locations, species lists, fractional cover, and plot descriptions to support the calibration of the airborne AVIRIS-NG imaging spectrometer. The data is structured in CSV and GeoJSON formats as part of a larger collection of biogeochemical and foliar measurements.

Use Cases

• Calibrating and validating AVIRIS-NG-derived vegetation indices and fractional cover maps using ground-measured plot data.
• Analyzing species composition and community structure across coastal, salt marsh, and preserve ecosystems.
• Studying phenological changes over a seven-month period through weekly synchronized field and airborne observations.
• Linking plot-level biogeochemical samples with spectral signatures for trait modeling.

Strengths

• Data collection was synchronized with weekly AVIRIS-NG overflights, enabling direct temporal matching for validation.
• Covers three distinct coastal reserve ecosystems in Santa Barbara County over a seven-month period.
• Includes geospatial plot polygons (GeoJSON) for precise location mapping.

Limitations

• Critical metadata conflicts exist: row counts, file sizes, and specific column names are unknown across all platforms.
• License information is inconsistently reported as 'other-license-specified' or null, requiring further investigation.
