Historical Shoreline Data for Ludington Harbor, Lake Michigan

A high-resolution historical shoreline dataset for Ludington Harbor on Lake Michigan, automated for use as a GIS data layer. The data are derived from shoreline maps produced by the NOAA National Ocean Service and its predecessor agencies, based on imagery interpretation and field surveys. Attribution follows the NGS-developed C-COAST scheme, influenced by the International Hydrographic Organization's S-57 standard.

Use Cases

• Analyze historical shoreline change based on high-resolution mapping data.
• Create GIS base layers for coastal management and planning.
• Validate or train coastal erosion models based on interpreted imagery and survey data.
• Translate shoreline data into S-57 compliant formats for hydrographic applications.

Strengths

• Data are described as high-resolution and accurate for GIS use.
• Attribution follows a structured scheme (C-COAST) influenced by an international standard (S-57).
• 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 file size are unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to the specific harbor location and historical survey methods.
