Historical Shoreline Data for Manistee and Portage Lakes, Lake Michigan

A high-resolution historical shoreline dataset for Manistee, Manistee Lake, and Portage Lake on Lake Michigan, suitable for GIS applications. The data were automated from shoreline maps produced by the NOAA National Ocean Service and its predecessor agencies, based on imagery interpretation and field surveys. The attribution follows the NOAA-developed C-COAST scheme, influenced by the S-57 standard for hydrographic data.

Use Cases

• Analyze historical shoreline change based on high-resolution automated shoreline data.
• Create GIS data layers for coastal management based on NOAA-derived shoreline maps.
• Translate shoreline attribution for hydrographic systems based on the C-COAST scheme influenced by S-57.

Strengths

• Data were automated to provide high-resolution historical shoreline.
• Derived from authoritative NOAA National Ocean Service shoreline maps.
• Attribution scheme (C-COAST) was developed to conform various sources and align with S-57 standards.

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 formats are limited to PDF and HTML, which may require conversion for direct GIS use.
