Hawaiian Islands hyperspectral imagery was collected to develop coral reef mapping methods. The AURORA system captured 72 spectral bands in the visible and near-infrared range at 3-meter pixel resolution. This cooperative project 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 improved feature detection in shallow and deep water.
- Compare habitat maps generated from hyperspectral imagery against those from IKONOS satellite or aerial photography.
- Analyze coral health and reef community structure through time-series analysis enabled by spectral bandwidth control.
- Delineate feature boundaries for habitat digitization using the processed band widths optimized for the environment.
Strengths
- 72 ten-nanometer spectral bands in the visible and near-infrared range provide detailed spectral resolution.
- 3-meter pixel resolution offers high spatial detail for coastal feature analysis.
- Data processed to optimize band widths for specific feature detection in different water depths.
Limitations
- Data is from approximately the year 2000, making it temporally stale for current ecological analysis.
- Specific sample size, geographic extent beyond 'Main Eight Hawaiian Islands', and file details are unknown.
