IKONOS satellite imagery was purchased and processed for coral mapping activities in American Samoa. The dataset includes one-meter panchromatic and four-meter multispectral data for Swains Island. The imagery was processed to minimize atmospheric and water column effects to support coral health and time series analysis.
Use Cases
- Delineate coral reef feature boundaries based on processed multispectral imagery.
- Analyze coral reef health over time based on enhanced spectral resolution.
- Support coastal habitat digitization projects based on imagery optimized for computer monitor interpretation.
Strengths
- Includes both one-meter panchromatic and four-meter multispectral data.
- Imagery was processed to minimize atmospheric and water column effects.
- Enhanced spectral resolution provides an advantage over color aerial photography for coral analysis.
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.
