NOAA Shoreline Mapping: Sacramento River Vector Data from Sacramento to Garcia Bend

NOAA's National Geodetic Survey provides a high-resolution vector shoreline for the Sacramento River between Sacramento Bend and Garcia Bend, California. The data is compiled from imagery and structured using the C-COAST attribution scheme to align with international hydrographic standards. This resource is part of a larger NOAA shoreline mapping program, with metadata last updated in March 2026.

Use Cases

• Integrate shoreline data into GIS for change detection analysis based on the high-resolution vector line data.
• Model riverbank erosion or accretion over time using the spatially accurate shoreline geometry.
• Create base maps for environmental planning and management in the Sacramento River region.
• Translate shoreline attributes for hydrographic chart production based on the C-COAST scheme influenced by S-57 standards.

Strengths

• Data is described as 'accurate high-resolution shoreline' compiled from imagery.
• Attribution follows the structured C-COAST scheme, designed for compatibility with international hydrographic standards.
• Metadata is available for both line and point shapefiles, indicating structured documentation.

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 available only in PDF and HTML formats, which may require conversion for direct GIS use.
