NOAA's Hyperspectral Imagery for the Main Eight Hawaiian Islands project developed methods for coral reef mapping. The dataset contains 72 spectral bands of visible and near-infrared imagery at a 3-meter pixel resolution, collected by the AURORA system. This cooperative effort involved NOAA, the University of Hawaii, and Analytical Laboratories of Hawaii, with data processed around the year 2000.
Use Cases
- Classify benthic habitat types using 72 spectral bands for feature detection in shallow and deep water.
- Analyze coral reef community structure over time by comparing maps from hyperspectral and IKONOS satellite imagery.
- Assess coral health by leveraging the enhanced spectral resolution of hyperspectral data over standard aerial photography.
- Delineate habitat boundaries for mapping by photointerpreting the georeferenced hyperspectral imagery.
Strengths
- High spectral resolution with 72 ten-nanometer bands in the visible and near-infrared range.
- Fine spatial detail with a 3-meter pixel resolution for feature delineation.
Limitations
- Data is temporally stale, with a last updated date of January 1, 2000.
- Specific sample size, row count, and geographic coverage beyond Oahu are unknown.
