Historical Shoreline of Sacramento River, CA, from NOAA Maps

Sacramento River, California, 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 office interpretation of imagery and/or field surveys. Attribution follows the NGS-developed C-COAST scheme, influenced by the IHO S-57 standard for translation.

Use Cases

• Analyze historical shoreline change based on the high-resolution GIS data layer.
• Integrate historical coastal features into modern GIS systems based on the C-COAST attribution scheme.
• Validate or compare modern shoreline data against historical baselines derived from NOAA maps.

Strengths

• Data were automated to provide an accurate high-resolution historical shoreline.
• Derived from shoreline maps produced by the authoritative NOAA National Ocean Service.
• Attribution follows a structured scheme (C-COAST) influenced by the IHO 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 the temporal and methodological bias inherent to the original historical maps.
