NOAA Shoreline Data Rescue Project for the Delaware River, Pennsylvania

NOAA's National Ocean Service provides a high-resolution historical shoreline dataset for the Delaware River in Pennsylvania, derived from office interpretation of imagery and field surveys. The data are structured using the NGS C-COAST attribution scheme to facilitate translation into the S-57 hydrographic standard. This dataset was last updated on March 13, 2026.

Use Cases

• Analyze historical shoreline change over time based on the high-resolution historical shoreline data.
• Create GIS data layers for coastal zone management based on the derived shoreline maps.
• Translate shoreline data into S-57 hydrographic format based on the C-COAST attribution scheme.

Strengths

• Data are described as providing an accurate high-resolution historical shoreline.
• Derived from shoreline maps produced by NOAA National Ocean Service and its predecessor agencies.
• Attribution scheme (C-COAST) was developed to conform various data sources into one catalog.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data are available only in PDF and HTML formats, which may limit direct geospatial analysis.
