Hyperspectral imagery data was collected for mapping and analyzing coral reef benthic habitats around the eight main Hawaiian Islands. The project was a cooperative effort involving NOAA's National Centers for Coastal Ocean Science, the University of Hawaii, and Analytical Laboratories of Hawaii. Data collection and processing occurred around the year 2000.
Use Cases
- Classify benthic habitat types using 72 spectral bands in the visible and near-infrared range.
- Compare habitat maps generated from hyperspectral imagery against those from color aerial photography or IKONOS satellite data.
- Analyze coral health and reef community structure over time using the enhanced spectral resolution for feature detection.
- Delineate boundaries of underwater features via photointerpretation of the 3-meter pixel resolution imagery.
Strengths
- 72 spectral bands provide high-resolution data for feature discrimination.
- 3-meter pixel resolution offers detailed spatial information for habitat mapping.
Limitations
- Data is from approximately the year 2000, limiting analysis of recent coral reef conditions.
- Specific sample size, geographic extent, and data completeness metrics are unknown.
