Historical Shoreline Data for Delaware River from Stony Point, NJ to Goose Point, DE

A high-resolution historical shoreline dataset for the Delaware River between Stony Point, New Jersey, and Goose Point, Delaware. The data were automated from shoreline maps produced by the NOAA National Ocean Service and its predecessors, based on imagery interpretation and field surveys. It uses the NGS C-COAST attribution scheme to facilitate translation into international hydrographic standards.

Use Cases

• Modeling historical shoreline erosion or accretion based on the high-resolution automated shoreline.
• Integrating a standardized shoreline layer into a GIS based on the C-COAST attribution scheme.
• Analyzing coastal zone changes over time based on the historical maps derived from imagery and surveys.

Strengths

• Data is described as high-resolution and accurate for GIS use.
• Shoreline attribution follows a structured scheme (C-COAST) influenced by international standards.

Limitations

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