72 spectral bands in the visible and near-infrared range were collected by the AURORA hyperspectral imaging system at 3-meter pixel resolution. This dataset was developed through a cooperative project involving NOAA's National Centers for Coastal Ocean Science, the University of Hawaii, and Analytical Laboratories of Hawaii, LLC to map coral reef habitats. The primary data collection and processing occurred around the year 2000.
Use Cases
- Compare benthic habitat maps generated from hyperspectral imagery against those from color aerial photography or IKONOS satellite imagery.
- Analyze coral reef community structure over time using the 72 ten-nanometer spectral bands for time series analysis.
- Detect features in shallow and deep water by utilizing processed band widths optimized for different environmental conditions.
- Delineate boundaries of benthic features through photointerpretation of the 3-meter resolution georeferenced imagery.
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 sample size (rows/area) and geographic coverage details for the eight islands are unknown.
