NOAA Shoreline Data Rescue Project for Ontonagon Harbor, Michigan

A high-resolution historical shoreline dataset for Ontonagon Harbor and Vicinity, Michigan, automated for use as a GIS data layer. The data were derived from shoreline maps produced by the NOAA National Ocean Service and its predecessors, based on imagery interpretation and field surveys. It uses the NGS C-COAST attribution scheme, influenced by the IHO S-57 standard, to facilitate data translation.

Use Cases

• Analyze historical shoreline change based on high-resolution geospatial data.
• Create coastal base maps for GIS applications based on NOAA-derived shoreline features.
• Translate shoreline data into S-57 compliant formats based on the C-COAST attribution scheme.
• Study coastal morphology in the Great Lakes region based on the specific geographic focus.

Strengths

• Data is described as high-resolution and accurate for GIS use.
• Derived from authoritative NOAA National Ocean Service shoreline maps.
• Attribution scheme (C-COAST) is designed for compatibility with the IHO S-57 standard.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Available file formats are PDF and HTML, which may not be the primary geospatial data formats.
