NOAA Shoreline Mapping: Back Bays from Duck to Knotts Island, NC-VA

A high-resolution vector shoreline dataset for the Back Bays region from Duck to Knotts Island, North Carolina and Virginia. The data was compiled by the National Oceanic and Atmospheric Administration from lidar and imagery, following the NGS C-COAST attribution scheme. The metadata describes both line and point shapefiles suitable for GIS applications.

Use Cases

• Conducting coastal erosion analysis based on the high-resolution vector shoreline data.
• Integrating shoreline layers into GIS for coastal zone management based on the described shapefiles.
• Translating shoreline data for hydrographic charting based on the C-COAST attribution scheme influenced by S-57 standards.

Strengths

• Data is derived from high-resolution lidar and imagery sources.
• Shoreline attribution follows a structured scheme (C-COAST) designed for translation into international hydrographic standards.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
