Historical Shoreline of the Saco River, Maine, Derived from NOAA Maps

Saco River, Maine shoreline data automated to provide a high-resolution historical GIS 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 International Hydrographic Organization's S-57 standard.

Use Cases

• Analyze historical shoreline change based on high-resolution mapping.
• Integrate historical coastal features into a GIS based on the described geospatial layer.
• Translate coastal cartographic data into S-57 standard formats based on the C-COAST attribution scheme.

Strengths

• Data provides a high-resolution historical shoreline suitable for GIS.
• Derived from authoritative NOAA National Ocean Service maps.
• Attribution scheme designed for compatibility with the S-57 hydrographic standard.

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 may reflect temporal and methodological bias inherent to the original map production era.
