Accuracy Assessment point data was created to validate benthic habitat maps derived from three distinct remote sensing platforms: aerial photography, hyperspectral, and IKONOS satellite imagery. The project was a cooperative effort between NOAA's National Centers for Coastal Ocean Science, the University of Hawaii, and Analytical Laboratories of Hawaii. Data generation was completed around the year 2000.
Use Cases
- Validate benthic habitat classification accuracy by comparing map labels against ground-truth assessment points.
- Compare the mapping performance and error rates between aerial photography, hyperspectral, and IKONOS satellite imagery sources.
- Assess the relationship between pixel size (e.g., three-meter IKONOS) and achievable map accuracy (e.g., 90-95% confidence interval).
- Identify habitat types where field observation is most critical to compensate for limitations in satellite-derived maps.
Strengths
- Data supports accuracy assessment for maps targeting a 90% to 95% confidence interval.
- Compares results from three distinct remote sensing platforms (aerial, hyperspectral, IKONOS).
Limitations
- Data is temporally stale, with a last update in 2002.
- Specific sample size (row count) and geographic point density are unknown.
- Underlying habitat map details and column schema are unspecified.
