Multispectral IKONOS satellite imagery at four-meter pixel resolution supports coral reef and benthic habitat mapping for the main eight Hawaiian Islands. The dataset was produced through a cooperative effort involving NOAA's National Centers for Coastal Ocean Science, the University of Hawaii, and Analytical Laboratories of Hawaii. It was collected and processed around the year 2000 to compare mapping methods using different imagery sources.
Use Cases
- Compare benthic habitat maps generated from IKONOS multispectral bands (blue, green, red, near-infrared) against those from aerial photography.
- Analyze coral reef community structure over time using the processed imagery with minimized atmospheric and water column effects.
- Delineate boundaries of benthic features like coral patches or seagrass beds using the four-meter resolution imagery within a habitat digitizer software.
Strengths
- Multispectral imagery includes four specific spectral bands (blue, green, red, near-infrared).
- Imagery was processed to minimize atmospheric and water column effects for improved analysis.
- Covers the main eight Hawaiian islands, providing a regional coastal perspective.
Limitations
- Data is from approximately the year 2000, making it temporally stale for current reef condition analysis.
- Specific sample size, row count, and file size metrics are unknown.
- The four-meter pixel resolution may be coarse for identifying small-scale reef features.
