Shoreline Data Rescue Project: Historical Shoreline of Sacramento River Valley, CA

Sacramento River Valley, California, is covered by a high-resolution historical shoreline dataset automated for GIS use. The data are derived from NOAA National Ocean Service shoreline maps 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

• Analyze historical shoreline change based on high-resolution geospatial data.
• Create GIS base layers for coastal planning and management.
• Validate or integrate shoreline data using the C-COAST attribution scheme.
• Study river valley geomorphology using interpreted imagery and survey data.

Strengths

• Data are described as high-resolution and accurate for GIS applications.
• Derived from authoritative NOAA National Ocean Service maps.
• Attribution scheme is designed for translation into the S-57 hydrographic standard.

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 may reflect geographic and temporal bias inherent to the source maps.
