Northeast Puerto Rico and Culebra Island underwater photos and videos from GPS-positioned points in shallow water benthic habitats. NOAA, with local DRNA and contractors, collected this accuracy assessment data in September 2014. The data was used to evaluate error in habitat polygon maps created by the Biogeography Team.
Use Cases
- Validate benthic habitat polygon classifications by comparing them to GPS-positioned underwater photo/video observations.
- Assess spatial error rates in habitat delineation using point-based accuracy assessment data.
- Model habitat distribution by correlating observed benthic features from videos with environmental variables.
- Calibrate remote sensing algorithms for shallow water mapping using ground-truth video and photo locations.
Strengths
- Data collected during a focused field campaign from September 3-15, 2014.
- Covers a specific geographic area including nearshore waters, reserves, and islands around Northeast Puerto Rico.
Limitations
- Sample size and number of assessment points are unknown.
- Data is from a single time period in 2014, limiting temporal analysis.
- Specific columns, file formats, and data volume are not provided.
