Historical Shoreline of Amagansett, NY from 1896 NOAA Maps

A high-resolution historical shoreline data layer for Amagansett and Vicinity, New York, derived from 1896 maps produced by the NOAA National Ocean Service and its predecessor agencies. The data were automated for GIS use and attributed using the NGS-developed C-COAST scheme, influenced by the International Hydrographic Organization's S-57 standard. This resource is a member of a larger NOAA data collection.

Use Cases

• Analyze historical shoreline change based on the high-resolution 1896 map data.
• Create GIS basemaps for coastal management based on the automated, attributed shoreline layer.
• Validate or translate coastal data into S-57 standards based on the C-COAST attribution scheme.
• Study coastal erosion or accretion patterns in New York based on the historical geographic data.

Strengths

• Data is derived from authoritative NOAA National Ocean Service historical maps.
• Shoreline is described as high-resolution and accurate for GIS use.
• Attribution uses a structured scheme (C-COAST) designed for translation to international standards.

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 is based on 1896 maps; modern shoreline conditions require supplemental data.
