NOAA NCEI's project provides hyperspectral imagery of the main eight Hawaiian Islands, focusing on Maui, for coral reef and benthic habitat mapping. The AURORA system collected data across 72 spectral bands in the visible and near-infrared range with 3-meter pixel resolution. This cooperative effort involved NOAA, the University of Hawaii, and Analytical Laboratories of Hawaii, with data processed around the year 2000.
Use Cases
- Compare benthic habitat maps generated from hyperspectral imagery against those from color aerial photography and 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 feature detection in the imagery.
- Delineate boundaries of benthic features for habitat mapping using the spectral data within software interfaces like the Habitat Digitizer.
Strengths
- 72 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.
Limitations
- Data is from approximately the year 2000, making it temporally stale for current ecological analysis.
- Specific row counts, file sizes, and geographic extents beyond 'main eight Hawaiian Islands' are unknown.
