The data is structured using the NGS C-COAST attribution scheme, influenced by the IHO S-57 standard for compatibility. It is a member of the NOAA InPort catalog and was last updated in April 2026.

Use Cases

• Integrate shoreline as a GIS data layer for coastal zone management based on the high-resolution vector data.
• Analyze shoreline change and coastal morphology based on the office-interpreted imagery.
• Translate shoreline data for hydrographic charting systems based on the attribution scheme influenced by the IHO S-57 standard.

Strengths

• Data is described as 'accurate high-resolution shoreline' compiled from imagery.
• Attribution uses the structured NGS C-COAST scheme for consistency.
• Data is part of the authoritative NOAA InPort catalog (item 39808).
