CORAL Experiment Hyperspectral Reef Composition Data

The CORAL Earth Venture Suborbital-2 mission provides a uniform picture of coral reef composition across the Mariana Islands, Palau, portions of the Great Barrier Reef, and the Main Hawaiian Islands. Data is collected using the Portable Remote Imaging Spectrometer (PRISM) instrument aboard a Gulfstream-IV aircraft, combined with in situ measurements. The dataset is produced by the National Aeronautics and Space Administration.

Use Cases

• Modeling reef primary production using combined airborne spectrometer and in situ data.
• Identifying and classifying coral reef composition from hyperspectral imagery.
• Analyzing spatial patterns of ocean chemistry, optics, temperature, and salinity across major reef systems.
• Comparing reef health metrics across distinct geographic regions like the Great Barrier Reef and Hawaiian Islands.

Strengths

• Covers four major Pacific reef regions, providing broad geographic coverage.
• Combines airborne hyperspectral data (PRISM) with in situ measurements for validation.
• Mission is part of a structured NASA Earth Venture Suborbital-2 program.

Limitations

• Key technical details like row count, file size, and specific column names are unavailable across all platforms.
• License is ambiguously listed as 'other-license-specified' without clear terms.
• Data formats (BIN, ISO) are specialized and may require specific tools for access.
