Shoreline Data Rescue Project: Historical Delaware River Coastline

Delaware River shoreline data were automated to provide a high-resolution historical coastline suitable for GIS. The data are derived from NOAA National Ocean Service shoreline maps based on imagery interpretation and field surveys. The attribution follows the NGS-developed C-COAST scheme, influenced by the S-57 standard for hydrographic data.

Use Cases

• Analyze historical shoreline change based on high-resolution coastline data.
• Create GIS basemap layers for the Delaware River region.
• Translate coastal data into S-57 hydrographic standard formats based on the C-COAST attribution scheme.
• Validate modern shoreline surveys against historical interpretations.

Strengths

• Data were automated for accuracy as a high-resolution GIS layer.
• Derived from NOAA National Ocean Service maps, an authoritative source.
• Attribution scheme designed for translation into the S-57 hydrographic standard.

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 are provided in PDF and HTML formats, which are not ideal for direct geospatial analysis.
