Hawaiian Islands Hyperspectral Imagery for Coral Reef Mapping

2000 hyperspectral imagery project focused on mapping coral reefs and benthic habitats across the Main Eight Hawaiian Islands, specifically Maui. The data was collected by a cooperative effort involving NOAA's National Centers for Coastal Ocean Science, the University of Hawaii, and Analytical Laboratories of Hawaii. It includes 72 spectral bands in the visible and near-infrared range with 3-meter pixel resolution.

Use Cases

• Classify benthic habitat types using 72 spectral bands from the AURORA hyperspectral imaging system.
• Compare habitat maps generated from hyperspectral imagery against those from IKONOS satellite or aerial photography.
• Analyze coral health and reef community structure over time using the optimized spectral band widths for feature detection.
• Delineate boundaries of underwater features for habitat digitization using the georeferenced 3-meter resolution imagery.

Strengths

• High spectral resolution with 72 ten-nanometer bands in the visible and near-infrared range.
• Fine spatial resolution of 3 meters per pixel for detailed feature analysis.
• Data processed with optimized band widths for feature detection in both shallow and deep water.

Limitations

• Temporal staleness, with data last updated in the year 2000.
• Specific sample size, row count, and geographic extent beyond the Hawaiian Islands are unknown.
• Data collection methodology and instrument specifics for the AURORA system may not be fully detailed.
