Hawaiian Islands Coral Reef Hyperspectral Imagery

Hyperspectral imagery data for the main eight Hawaiian Islands, focused on Oahu, was collected to develop coral reef mapping methods. The project involved NOAA's National Centers for Coastal Ocean Science, the University of Hawaii, and Analytical Laboratories of Hawaii. Data collection and processing occurred around the year 2000.

Use Cases

• Classify benthic habitat types by analyzing 72 spectral bands in the visible and near-infrared range.
• Compare coral reef maps generated from hyperspectral imagery against those from IKONOS satellite or aerial photography.
• Assess coral health and community structure changes through time-series analysis of spectral signatures.
• Delineate feature boundaries for habitat mapping using 3-meter pixel resolution imagery.

Strengths

• 72 spectral bands with 10 nm bandwidths provide detailed spectral resolution.
• 3-meter pixel resolution offers fine spatial detail for feature delineation.

Limitations

• Data is from approximately the year 2000, limiting analysis of recent coral reef conditions.
• Specific sample size (number of images or area covered) is not provided.
• Focus on Hawaiian Islands may limit geographic generalizability.
