Permafrost Polygon Features for Hay Lake Area

GIS data from the Government of Alberta depicts permafrost areas within the Hay Lake region (NTS 84L/NE). It consists of polygon features created in ArcInfo format and distributed for public use. The dataset was last updated in March 2026.

Use Cases

• Classify permafrost extent from polygon geometry and attributes for regional hazard mapping.
• Analyze the relationship between surficial geology units and permafrost polygon features.
• Integrate polygon boundaries with other geospatial layers for environmental impact assessments.

Strengths

• Polygon features provide detailed spatial boundaries for permafrost analysis.
• Data is provided in multiple standard GIS formats (E00, shapefile) for interoperability.
• Maintained by a government authority (Government of Alberta), suggesting formal data collection.

Limitations

• Specific row count, column names, and sample data are unavailable for assessing volume and detail.
• The dataset covers a single map sheet area (84L/NE), limiting broader regional analysis without joining other sheets.
