NOAA Shoreline Mapping Program: Chesapeake and Delaware Canal Vector Data

A high-resolution vector shoreline dataset for the Chesapeake and Delaware Canal, compiled from imagery by the National Oceanic and Atmospheric Administration. The data includes both line and point shapefiles, attributed using the NGS-developed C-COAST scheme for compatibility with hydrographic standards. This resource is part of a larger NOAA shoreline mapping program.

Use Cases

• Conducting coastal change analysis based on high-resolution vector shoreline data.
• Integrating shoreline layers into GIS for maritime navigation or planning.
• Translating shoreline data into S-57 hydrographic formats based on the C-COAST attribution scheme.
• Performing office-based interpretation of coastal imagery for mapping purposes.

Strengths

• Data is described as 'accurate high-resolution shoreline' compiled from imagery.
• Attribution uses the NGS-developed C-COAST scheme, designed for compatibility with international hydrographic standards.
• Data is provided by the authoritative National Oceanic and Atmospheric Administration.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific canal location.
