Shoreline Mapping of the St. Lawrence River from Howe Island to Wellesley Island

A high-resolution vector shoreline dataset for the St. Lawrence River between Howe Island and Wellesley Island, compiled from imagery. The data, attributed using NOAA's C-COAST scheme, is suitable as a GIS layer. This resource is part of NOAA's Shoreline Mapping Program and was last updated in March 2026.

Use Cases

• Integrating shoreline data into Geographic Information Systems (GIS) based on the description of its suitability as a GIS layer.
• Analyzing coastal features and changes based on the high-resolution vector shoreline data.
• Translating shoreline attribution for hydrographic systems based on the C-COAST scheme's influence by S-57 standards.

Strengths

• Data is described as high-resolution and accurate.
• Shoreline attribution follows a structured scheme (C-COAST) influenced by international hydrographic standards.
• Last updated on 2026-03-13, indicating recent maintenance.

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 bias inherent to the specific river segment surveyed.
