The data uses the NGS C-COAST attribution scheme to conform various shoreline data sources into a single catalog.

Use Cases

• Analyze coastal erosion or accretion over time based on the historical shoreline data.
• Create GIS data layers for coastal zone management based on the high-resolution shoreline.
• Translate shoreline data into S-57 hydrographic formats based on the C-COAST attribution scheme.
• Validate modern shoreline models against historical interpretations based on the NOAA-derived maps.

Strengths
