Great Lakes Shoreline Ecosystem Inventory With Two-Kilometer Inland Zone

An updated geospatial inventory replaces earlier versions 1.0 and 2.0, covering the entire Canadian Great Lakes shoreline. The Government of Ontario produced this dataset, which extends from the land-water interface to two kilometers inland and includes connecting channels. It was last updated in March 2026.

Use Cases

• Classify ecosite polygons using the detailed GLSE classification system for habitat mapping.
• Calibrate remote sensing models with field survey calibration point data for improved accuracy.
• Analyze ground-level ecological data associated with polygons to assess species distribution.
• Map wetland interface changes along the shoreline using the inland boundary data.

Strengths

• Full coverage of the Canadian Great Lakes shoreline and connecting channels.
• Integrates data from two prior mapping product versions (1.0 and 2.0).
• Includes ground-level ecological data for field validation.

Limitations

• Specific row counts, column details, and sample sizes are not provided.
• Geographic scope is limited to the Canadian side of the Great Lakes.
