American Samoa's Rose Atoll is covered by one-meter panchromatic and four-meter multispectral IKONOS satellite imagery. The data was purchased and processed by a cooperative effort involving NOAA's National Ocean Service, the University of Hawaii, and Analytical Laboratories of Hawaii to support coral reef mapping and GIS projects. Imagery was processed to minimize atmospheric and water column effects for habitat delineation.
Use Cases
- Delineating coral reef habitat boundaries based on high-resolution panchromatic and multispectral imagery.
- Analyzing coral reef community structure over time using the enhanced spectral resolution of the data.
- Assessing coral health by leveraging processed imagery with minimized atmospheric and water column effects.
- Supporting coastal GIS projects and marine spatial planning for the Pacific Islands region.
Strengths
- Includes both one-meter panchromatic and four-meter multispectral data for each study area.
- Imagery was processed to minimize atmospheric and water column effects for improved analysis.
- Data was acquired through a cooperative project involving NOAA, a university, and a laboratory.
Limitations
