CM-8001: Historical Shoreline Data for Saginaw River, Michigan

NOAA's Shoreline Data Rescue Project CM-8001 provides a high-resolution historical shoreline for the Saginaw River, Michigan, suitable as a GIS data layer. The data are derived from shoreline maps produced by the NOAA National Ocean Service and its predecessors, based on imagery interpretation and field surveys. 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 management and planning.
• Translate shoreline features into S-57 compliant formats for hydrographic systems.
• Conduct coastal erosion or accretion studies using historical map interpretations.

Strengths

• Data are described as high-resolution and accurate for GIS use.
• Attribution follows a structured scheme (C-COAST) influenced by an international hydrographic standard.
• Source lineage is documented, originating from NOAA National Ocean Service maps.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset scale are unknown, which may limit suitability assessment.
• Data formats are limited to PDF and HTML, which may not be ideal for direct geospatial analysis.
