Hyperspectral imagery data was collected for coral reef mapping and benthic habitat analysis around the main Hawaiian Islands. The project involved NOAA's National Centers for Coastal Ocean Science, the University of Hawaii, and Analytical Laboratories of Hawaii. Data was collected and processed around the year 2000.
Use Cases
- Compare benthic habitat maps generated from hyperspectral imagery versus color aerial photography and IKONOS satellite data.
- Analyze coral health and community structure over time using 72 spectral bands in the visible and near-infrared range.
- Delineate feature boundaries in shallow and deep water using processed band widths optimized for detection.
- Develop coral reef mapping methods with 3-meter pixel resolution hyperspectral data from the AURORA system.
Strengths
- 72 spectral bands collected in the visible and near-infrared range.
- 3-meter pixel resolution for detailed spatial analysis.
Limitations
- Data is from approximately the year 2000, limiting analysis of recent reef conditions.
- Specific row counts, file sizes, and geographic extents for Oahu are unknown.
