PRISM Hyperspectral Imagery of Elkhorn Slough Coastal Habitats

Elkhorn Slough in Monterey Bay, California, is the study site for this dataset, which contains hyperspectral imagery and in-situ validation data from July 2012. The data was collected using the Portable Remote Imaging SpectroMeter (PRISM) sensor, offering high spatial resolution up to 30 cm and spectral resolution of 3 nm. The dataset was produced by the National Aeronautics and Space Administration for validating imaging spectroscopy in turbid coastal waters.

Use Cases

• Analyzing inherent optical properties of turbid, sediment-laden waters using hyperspectral bands.
• Mapping and classifying coastal habitats such as eelgrass beds and salt marshes based on spectral signatures.
• Validating and calibrating remote sensing algorithms for coastal ocean processes with concurrent in-situ measurements.
• Studying the spatial distribution of benthic targets at a resolution of up to 30 cm.

Strengths

• Sensor provides high spatial resolution up to 30 cm and spectral resolution of 3 nm.
• Dataset includes concurrent in-situ sampling for validation of water column optical properties and benthic targets.
• Cross-platform presence on Data.gov and NASA EarthData indicates recognized importance for coastal research.

Limitations

• Exact row count, column names, and dataset size are unknown across all sources.
• Sources conflict on license details: Data.gov lists 'other-license-specified' while NASA EarthData lists 'None'.
• Temporal coverage is limited to a single campaign in July 2012.
