Historical Shoreline of Sakonnet Point to Apponaganset Bay, RI and MA, 1936

NOAA National Ocean Service provides a high-resolution historical shoreline for a Rhode Island and Massachusetts coastal region, automated for GIS use. The data are derived from office interpretations of imagery and field surveys, attributed using the NGS-developed C-COAST scheme. This resource is part of a larger NOAA data collection identified as item 39808.

Use Cases

• Analyze historical shoreline change based on the high-resolution mapping mentioned in the description.
• Train coastal erosion models based on the attributed geospatial data layer.
• Integrate historical coastline data into modern GIS systems based on the automated format.
• Study coastal cartographic standards based on the C-COAST attribution scheme.

Strengths

• Data is derived from authoritative NOAA National Ocean Service shoreline maps.
• Shoreline is described as high-resolution and accurate, suitable for GIS layers.
• Attribution uses a structured scheme (C-COAST) influenced by international hydrographic standards.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to the 1936 source maps.
