Permafrost Polygon Features for Chipewyan Lake Surficial Geology

A geospatial dataset depicting the surficial geology and discontinuous permafrost polygon features of the Chipewyan Lake area (NTS 84A/NW). It was created by the Alberta Geological Survey and published as part of Map 572. The data was last updated in March 2026.

Use Cases

• Analyze the spatial distribution of permafrost polygon features to model ground stability for construction planning.
• Correlate surficial geology units with permafrost presence to understand regional hydrogeology and ecosystem dynamics.
• Use the polygon boundaries as a base layer for environmental impact assessments in the discontinuous permafrost zone.

Strengths

• Data is derived from the authoritative Alberta Geological Survey Map 572.
• Covers a specific, defined map area (NTS 84A/NW).
• Published in standard geodatabase and shapefile formats for GIS interoperability.

Limitations

• The specific number of polygon features, rows, and file size is unknown.
• No column or attribute schema is provided, limiting detailed analysis of feature properties.
• Temporal coverage of the underlying geological mapping is not specified.
