Hyperspectral imagery data was collected for the main eight Hawaiian Islands to develop and compare coral reef mapping methods. The project was a cooperative effort involving NOAA's National Centers for Coastal Ocean Science, the University of Hawaii, and Analytical Laboratories of Hawaii, LLC. Data collection and processing occurred around the year 2000.
Use Cases
- Classify benthic habitats using 72 spectral bands in the visible and near-infrared range.
- Compare mapping accuracy between hyperspectral imagery, IKONOS satellite data, and color aerial photography.
- Analyze coral reef community structure over time with 3-meter pixel resolution imagery.
- Detect features in shallow and deep water by utilizing processed band widths optimized for the environment.
Strengths
- Imagery contains 72 spectral bands, each with a 10 nm bandwidth.
- Data offers a high spatial resolution of 3 meters per pixel.
Limitations
- The dataset's temporal recency is limited, with a last updated date of 2000-01-01.
- Specific sample size, geographic bounds, and file formats are not provided.
