NOAA's project provides hyperspectral imagery for coral reef mapping around Oahu. The AURORA system collected data across 72 spectral bands in the visible and near-infrared range. This cooperative effort involved NOAA, the University of Hawaii, and Analytical Laboratories of Hawaii, with data processed around the year 2000.
Use Cases
- Classifying benthic habitat types using 72 spectral bands for each 3-meter pixel.
- Comparing coral reef maps generated from hyperspectral data against IKONOS satellite and aerial photography.
- Analyzing coral health and community structure changes through time-series of spectral signatures.
- Developing feature detection algorithms optimized for shallow and deep water environments using selected band widths.
Strengths
- 72 spectral bands provide high spectral resolution for detailed feature analysis.
- 3-meter pixel resolution offers fine spatial detail for habitat boundary delineation.
Limitations
- Data is from approximately the year 2000, limiting analysis of recent coral reef conditions.
- Specific spatial extent, row count, and file size details are unknown.
- Imagery is focused on Oahu, limiting geographic generalizability.
