NOAA's National Centers for Coastal Ocean Science and partners acquired IKONOS satellite imagery to support coral reef mapping in the Pacific Islands. The collection includes one-meter panchromatic and four-meter multispectral data for American Samoa's Manua Islands, processed to reduce atmospheric and water effects. Data was published in 2002.
Use Cases
- Classify coral reef habitat boundaries using the high-resolution panchromatic and multispectral bands.
- Analyze changes in coral community structure over time with the time-series imagery.
- Assess coral health by leveraging the enhanced spectral resolution of the multispectral data.
- Delineate coastal features for GIS projects using the photointerpreted habitat boundaries.
Strengths
- Includes both 1-meter panchromatic and 4-meter multispectral data for each study area.
- Imagery was processed to minimize atmospheric and water column effects for clearer analysis.
Limitations
- Dataset is from 2002 and may be temporally stale for current ecological studies.
- Specific sample size, geographic extent for Manua Islands, and row counts are unknown.
