IKONOS satellite imagery was purchased to support coral mapping activities in the Pacific Islands. The dataset includes one-meter panchromatic and four-meter multispectral data for Tutuila Island, processed to minimize atmospheric and water column effects. This cooperative project involved the National Ocean Service, the University of Hawaii, and Analytical Laboratories of Hawaii, with data last updated in 2002.
Use Cases
- Delineating coral reef habitat boundaries based on high-resolution panchromatic and multispectral imagery.
- Conducting time series analysis of coral reef community structure based on enhanced spectral resolution.
- Assessing coral health based on controlled bandwidths of multispectral data.
- Supporting coastal GIS projects for Pacific Islands based on georeferenced satellite imagery.
Strengths
- Includes both one-meter panchromatic and four-meter multispectral data for detailed analysis.
- Imagery was processed to minimize atmospheric and water column effects for clearer interpretation.
- Project involved multiple authoritative organizations including NOAA's National Ocean Service.
Limitations
- Last updated 2002-01-01 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and file formats are unknown, which may limit suitability assessment.
