AURORA hyperspectral imaging system collected 72 spectral bands in the visible and near-infrared range for coral reef mapping. This data supports the development of methods to compare benthic habitat maps from aerial photography and satellite imagery. The project was a cooperative effort led by NOAA and partners, with data processed around the year 2000.
Use Cases
- Classify benthic habitat types using the 72 ten-nm spectral bands to distinguish coral, algae, and sand.
- Analyze coral health over time by comparing spectral signatures across the visible and near-infrared range.
- Validate habitat maps generated from IKONOS satellite imagery by using the higher spectral resolution hyperspectral data as ground truth.
- Optimize feature detection in shallow and deep water by processing the data to select specific band widths.
Strengths
- 72 spectral bands provide high spectral resolution for detailed feature analysis.
- 3-meter pixel resolution offers fine spatial detail for habitat delineation.
Limitations
- Data is from approximately the year 2000, limiting analysis of recent coral reef changes.
- Specific sample size (rows/images) and geographic coverage beyond Lanai are unknown.
