Hawaiian Islands Coral Reef Hyperspectral Imagery

72 spectral bands of hyperspectral imagery were collected for the main eight Hawaiian Islands, focusing on Oahu, with a 3-meter pixel resolution. The data was developed through a cooperative effort involving NOAA's National Centers for Coastal Ocean Science, the University of Hawaii, and Analytical Laboratories of Hawaii. The project aimed to compare coral reef mapping methods and was last updated in the year 2000.

Use Cases

• Compare benthic habitat maps generated from hyperspectral imagery versus color aerial photography or IKONOS satellite imagery.
• Analyze coral reef community structure over time using the 72 ten-nanometer spectral bands in the visible and near-infrared range.
• Delineate boundaries of benthic features using the 3-meter resolution imagery for habitat digitizer software.
• Optimize feature detection in shallow and deep water by processing the data to select specific band widths.

Strengths

• 72 spectral bands provide high spectral resolution for feature discrimination.
• 3-meter pixel resolution offers detailed spatial information for habitat delineation.

Limitations

• Data is from the year 2000 and may not reflect current reef conditions.
• Specific row count, file size, and sample data details are unavailable.
