AURORA hyperspectral imaging captured 72 spectral bands in the visible and near-infrared range for coral reef analysis. 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 were completed around the year 2000.
Use Cases
- Compare benthic habitat maps generated from hyperspectral bands versus IKONOS satellite imagery and aerial photography.
- Analyze coral reef community structure over time using the 72 ten-nm spectral bands for feature detection.
- Delineate boundaries of underwater features using the 3-meter pixel resolution georeferenced imagery.
- Optimize band selection from the hyperspectral data for detecting features in both shallow and deep water environments.
Strengths
- 72 spectral bands provide high-resolution data for feature discrimination.
- 3-meter pixel resolution offers detailed spatial information for mapping.
Limitations
- Data is from approximately the year 2000, limiting analysis of recent coral reef changes.
- Specific sample size (rows/image count) and geographic extent beyond Oahu are unknown.
