Accuracy Assessment point data were generated to evaluate benthic habitat maps created from three distinct remote sensing sources: color aerial photography, hyperspectral, and IKONOS satellite imagery. The project was a cooperative effort involving NOAA's National Centers for Coastal Ocean Science, the University of Hawaii, and Analytical Laboratories of Hawaii, LLC. Data collection and analysis were completed around the year 2000.
Use Cases
- Compare classification accuracy between maps derived from aerial photography, hyperspectral, and IKONOS satellite imagery using ground-truth point data.
- Validate benthic habitat map predictions by analyzing the relationship between observed habitat labels at assessment points and the source imagery type.
- Assess the impact of three-meter pixel resolution on achieving 90-95% confidence intervals for overall map accuracy.
- Model the trade-offs between field observation intensity and map accuracy for habitats mapped from IKONOS imagery.
Strengths
- Data supports accuracy assessment for maps targeting a 90% to 95% confidence interval.
- Derived from a multi-institutional project involving NOAA, academic, and private laboratory partners.
Limitations
- Dataset is temporally stale, with last update recorded in 2002.
- Specific sample size (row count) and geographic point density are unknown.
- Underlying map and point data column structures are unspecified.
