Wetland Spectral and Soil Data from Weekly NASA Airborne Campaign

NASA's 2022 SHIFT campaign provides paired field measurements and airborne imagery for a California estuary. The dataset includes soil salinity samples, fractional cover estimates for four classes, and derived vegetation indices like NDVI and CRSI. Data formats include GeoTIFF, CSV, and shapefiles for analysis.

Use Cases

• Correlating soil salinity measurements with airborne spectral reflectance data.
• Modeling fractional cover of vegetation classes using MESMA from AVIRIS-NG imagery.
• Analyzing vegetation health via derived indices like NDVI and the Canopy Response Stress Index.
• Time-series analysis of wetland changes using weekly flight data from February to September 2022.
• Spatial mapping of soil properties and vegetation cover within the Devereux Slough estuary.

Strengths

• Data pairs weekly high-resolution AVIRIS-NG airborne imagery with contemporaneous ground samples.
• Analysis provides four specific fractional cover classes and multiple vegetation/soil indices.
• Covers a seven-month time series from February 24 to September 16, 2022.
• Campaign is part of NASA's Surface Biology Geology (SBG) preparatory work, indicating scientific rigor.

Limitations

• Exact row counts, dataset size, and specific column names are not provided by any source.
• License is specified only as 'other-license-specified' on Data.gov, with no details on NASA Earthdata.
• Last update dates conflict between platforms: Data.gov shows 2026-03 -12, while NASA Earthdata shows 2024-05-30.
