Hyperspectral imagery of the main eight Hawaiian Islands was collected for coral reef and benthic habitat mapping. The project was a cooperative effort by 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 data against those from IKONOS satellite or aerial photography.
- Detect features in shallow and deep water by leveraging processed band widths optimized for feature detection.
- Analyze coral health and community structure changes over time using the enhanced spectral resolution of the imagery.
Strengths
- 72 spectral bands collected per image in the visible and near-infrared range.
- Imagery has a 3-meter pixel resolution for detailed spatial analysis.
Limitations
- Data is from approximately the year 2000, making it temporally stale for current ecological analysis.
- Specific sample size (row/area count) and file formats are unknown.
