NOAA Shoreline Data Rescue Project for Sturgeon Bay and Canal, Lake Michigan

NOAA's Shoreline Data Rescue Project provides a high-resolution historical shoreline for Sturgeon Bay and Canal, Lake Michigan, Wisconsin, as a GIS data layer. The data were automated from shoreline maps produced by the NOAA National Ocean Service and its predecessors, based on imagery interpretation and field surveys. The attribution follows the NGS-developed C-COAST scheme, influenced by the International Hydrographic Organization's S-57 standard.

Use Cases

• Historical shoreline change analysis based on high-resolution geospatial data.
• Coastal zone mapping and GIS layer creation based on automated shoreline vectors.
• Validation of modern shoreline datasets against historical NOAA survey data.
• Integration into hydrographic systems based on S-57-influenced attribution standards.

Strengths

• Data is derived from authoritative NOAA National Ocean Service shoreline maps.
• Shoreline is described as high-resolution and historically accurate.
• Attribution scheme (C-COAST) is designed for translation into the S-57 hydrographic standard.

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 freshness should be verified despite a listed update date of 2026-03 -13.
