Anatahan Island IKONOS Satellite Imagery for Coral Mapping

IKONOS satellite imagery provides one-meter panchromatic and four-meter multispectral data for Anatahan Island in the Northern Mariana Islands. The data was processed to minimize atmospheric and water column effects to support coral reef mapping and time series analysis. This project was a cooperative effort led by NOAA's National Centers for Coastal Ocean Science and partners, with imagery collected between 2001 and 2003.

Use Cases

• Analyze coral reef community structure using four-meter multispectral bands for time series analysis.
• Delineate habitat boundaries for coastal features using one-meter panchromatic imagery via a habitat digitizer.
• Assess coral health by leveraging the enhanced spectral resolution of the processed multispectral data.
• Support GIS projects for Pacific Islands by integrating georeferenced IKONOS imagery into spatial databases.

Strengths

• Imagery includes both high-resolution one-meter panchromatic and four-meter multispectral data.
• Data was specifically processed to reduce atmospheric and water column effects for marine applications.

Limitations

• Data is temporally stale, with collection ending in 2003 and no updates since.
• Specific technical details like file size, row/column counts, and exact geographic extents are unknown.
