One-meter panchromatic and four-meter multispectral IKONOS satellite imagery was collected for the Northern Mariana Islands between 2001 and 2003. The project was a cooperative effort involving NOAA's National Centers for Coastal Ocean Science, the University of Hawaii, and Analytical Laboratories of Hawaii. Imagery was processed to minimize atmospheric and water column effects for coral reef analysis.
Use Cases
- Delineating coral reef habitat boundaries using panchromatic imagery for GIS mapping.
- Analyzing coral health and community structure through time-series of multispectral bandwidth data.
- Assessing changes in coastal features by comparing processed imagery from 2001 to 2003.
Strengths
- Imagery provides one-meter panchromatic resolution for detailed feature delineation.
- Multispectral data offers four-meter resolution with enhanced spectral bandwidths for biological analysis.
- Data is processed to minimize atmospheric and water column effects, improving interpretability.
Limitations
- Data is temporally stale, with the last update in 2003, limiting contemporary analysis.
- Specific sample size, geographic extent within the islands, and file formats are unknown.
