Shoreline Mapping of the St. Lawrence River from Morristown to Massena

A high-resolution vector shoreline dataset for the St. Lawrence River between Morristown, NY and Massena, NY-ONT. The data was compiled by the National Oceanic and Atmospheric Administration (NOAA) from imagery interpretation and uses the C-COAST attribution scheme. It is suitable for use as a geographic information system (GIS) data layer.

Use Cases

• Conducting coastal erosion studies based on the high-resolution shoreline vector data.
• Creating or updating nautical charts based on the standardized C-COAST attribution scheme.
• Integrating shoreline data into regional GIS models for environmental planning.
• Analyzing river morphology changes using the interpreted imagery-based line and point features.

Strengths

• Data is described as providing an accurate high-resolution shoreline.
• Attribution follows the NOAA-developed C-COAST scheme, designed for consistency with international standards.
• Data is provided in both line and point vector shapefiles for GIS use.

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.
• The description metadata is limited; actual data quality requires manual inspection after download.
