Shoreline Data Rescue Project: Historical Coastline from Yonkers to 145th Street

A high-resolution historical shoreline dataset for the region from Yonkers to 145th Street, New York and New Jersey, automated for GIS use. The data were derived from shoreline maps produced by the NOAA National Ocean Service and its predecessor agencies, based on imagery interpretation and field surveys. Attribution follows the NGS-developed C-COAST scheme, influenced by the International Hydrographic Organization's S-57 standard.

Use Cases

• Analyzing historical shoreline change and erosion based on the high-resolution mapping mentioned in the description.
• Creating or validating coastal base maps in a GIS based on the derived shoreline data layer.
• Integrating historical coastal data with modern datasets based on the standardized C-COAST attribution scheme.

Strengths

• Data were automated to provide an accurate high-resolution historical shoreline suitable as a GIS data layer.
• Derived from authoritative NOAA National Ocean Service shoreline maps.
• Attribution follows a structured scheme (C-COAST) influenced by an international hydrographic standard (S-57).

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.
• The C-COAST attribution scheme is noted as not a recognized standard.
