72 spectral bands in the visible and near-infrared range were collected by the AURORA hyperspectral imaging system for coral reef mapping. The project was a cooperative effort among NOAA's National Centers for Coastal Ocean Science, the University of Hawaii, and Analytical Laboratories of Hawaii. Data was processed and published around the year 2000.
Use Cases
- Compare benthic habitat maps generated from hyperspectral imagery against those from IKONOS satellite and aerial photography.
- Analyze coral reef community structure over time using the 72 ten-nanometer spectral bands.
- Detect features in shallow and deep water by utilizing processed band widths optimized for feature detection.
- Delineate boundaries of benthic habitats via photointerpretation of the georeferenced hyperspectral data.
Strengths
- 72 spectral bands provide high spectral resolution for feature discrimination.
- 3-meter pixel resolution offers detailed spatial information for habitat mapping.
Limitations
- Data is from approximately the year 2000, limiting analysis of recent coral reef changes.
- Specific sample size (rows/image count) and geographic coverage beyond Oahu are unknown.
