Hyperspectral imagery data was collected for coral reef mapping and benthic habitat analysis around Molokai, Hawaii. The project was a cooperative effort involving NOAA's National Centers for Coastal Ocean Science, the University of Hawaii, and Analytical Laboratories of Hawaii. 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 and IKONOS satellite imagery.
- Analyze coral reef community structure over time using the 72 spectral bands in the visible and near-infrared range.
- Detect features in shallow and deep water by utilizing processed band widths optimized for feature detection.
- Delineate boundaries of benthic features using the 3-meter pixel resolution for precise habitat mapping.
Strengths
- 72 spectral bands collected in the visible and near-infrared range.
- Imagery has a 3-meter pixel resolution for detailed spatial analysis.
Limitations
- Data is from approximately the year 2000, limiting analysis of recent coral reef conditions.
- Specific row counts, file sizes, and detailed column information are unavailable.
