Shoreline Data Rescue Project: Historical Shoreline of Narragansett Bay-East Passage, RI

Narragansett Bay-East Passage, Rhode Island, is covered by a high-resolution historical shoreline dataset automated for GIS use. The data were derived from shoreline maps produced by the NOAA National Ocean Service and its predecessors, based on imagery interpretation and field surveys. The attribution follows the NGS-developed C-COAST scheme, influenced by the S-57 standard for hydrographic data.

Use Cases

• Historical shoreline change analysis based on the high-resolution historical shoreline data.
• GIS layer integration for coastal zone management based on the geographic information system data layer.
• Data translation and standardization for hydrographic systems based on the C-COAST attribution scheme influenced by S-57.
• Coastal cartographic object modeling based on the NOAA National Ocean Service's mapping methodology.

Strengths

• Data were automated to provide an accurate high-resolution historical shoreline.
• Derived from shoreline maps produced by the NOAA National Ocean Service and its predecessor agencies.
• Attribution follows the NGS-developed C-COAST scheme, influenced by the International Hydrographic Organization's S-57 standard.

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 source maps and interpretation methods.
