Hyperspectral imagery data was collected to develop and compare methods for mapping coral reef and benthic habitats around the main eight Hawaiian Islands, focusing on Oahu. The project was a cooperative effort involving 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 using 72 spectral bands in the visible and near-infrared range.
- Compare habitat map accuracy generated from hyperspectral imagery versus color aerial photography or IKONOS satellite data.
- Analyze coral reef health and community structure through time-series analysis of spectral signatures.
- Delineate feature boundaries for shallow and deep water environments using processed band widths optimized for detection.
Strengths
- 72 spectral bands at 10 nm resolution in the visible and near-infrared range.
- Imagery collected with a 3-meter pixel spatial resolution.
Limitations
- Data is temporally stale, with collection and last update around the year 2000.
- Specific sample size, geographic extent for Oahu, and file formats are unknown.
