Shoreline Mapping Program of Cape Charles to Delaware Bay, VA-MD-DE, VA1408-TB-C

NOAA's National Geodetic Survey provides a high-resolution vector shoreline compiled from lidar and imagery for the Cape Charles to Delaware Bay region. The data uses a specialized attribution scheme, C-COAST, designed to align with international hydrographic standards. This resource is part of a larger NOAA shoreline mapping program.

Use Cases

• Coastal change analysis based on high-resolution shoreline delineation.
• GIS layer integration for nautical charting based on the C-COAST attribution scheme.
• Validation of shoreline models based on lidar and imagery-derived vector data.
• Environmental impact assessment based on accurate coastal boundary data.

Strengths

• Data is described as 'accurate high-resolution' based on lidar and imagery.
• Attribution uses the C-COAST scheme, influenced by the international S-57 standard for hydrographic data.
• Last updated date is provided as 2026-03-13.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Available file formats are PDF and HTML, which may not be directly machine-readable for analysis.
