2000-era hyperspectral imagery for coral reef mapping on the main eight Hawaiian islands, focusing on Oahu. The data was collected by the AURORA system, providing 72 spectral bands at 3-meter resolution. This project was a cooperative effort involving NOAA's National Centers for Coastal Ocean Science, the University of Hawaii, and Analytical Laboratories of Hawaii.
Use Cases
- Classify benthic habitats using 72 ten-nm spectral bands in the visible and near-infrared range.
- Compare habitat maps generated from this hyperspectral imagery against those from IKONOS satellite or color aerial photography.
- Analyze coral reef community structure over time using the spectral resolution optimized for shallow and deep water feature detection.
- Delineate feature boundaries for habitat mapping using the 3-meter pixel resolution georeferenced imagery.
Strengths
- 72 spectral bands provide enhanced resolution for feature detection.
- 3-meter pixel resolution offers detailed spatial information.
Limitations
- Data is from the year 2000 and may be temporally stale for current ecological studies.
- Specific sample size (rows/image count) and geographic coverage details for Oahu are unknown.
