Hyperspectral Coral Reef Imagery of Lanai with 3-Meter Resolution

72 spectral bands in the visible and near-infrared range were collected by the AURORA hyperspectral imaging system for the Hawaiian island of Lanai. This dataset was created for developing coral reef mapping methods by a collaboration between NOAA's National Centers for Coastal Ocean Science, the University of Hawaii, and Analytical Laboratories of Hawaii. The data was processed and published around the year 2000.

Use Cases

• Classify benthic habitat types using the 72 ten-nanometer spectral bands for feature detection in shallow and deep water.
• Compare coral reef maps generated from this hyperspectral imagery against those from color aerial photography or IKONOS satellite imagery.
• Analyze coral health and community structure over time by leveraging the enhanced spectral resolution of the 3-meter pixel data.
• Delineate boundaries of underwater features for habitat digitization using the georeferenced imagery.

Strengths

• 72 spectral bands provide high spectral resolution for detailed feature analysis.
• 3-meter pixel resolution offers fine spatial detail for coastal and benthic mapping.

Limitations

• Data is from approximately the year 2000, limiting its use for contemporary change detection.
• Specific sample size (row/area count), file formats, and exact geographic bounds are unknown.
