Surficial Geology and Permafrost Polygons for Dizzy Creek Area

Alberta Geological Survey Map 540 provides GIS data depicting the surficial geology and discontinuous permafrost polygon features of the Dizzy Creek Area (NTS 84N/SE). The data were created by the Government of Alberta and released in shapefile format for public distribution. It was last updated in March 2026.

Use Cases

• Map permafrost polygon distribution and type using polygon geometry and attribute fields.
• Analyze the relationship between surficial geology units and permafrost occurrence via geological feature labels.
• Model terrain stability for engineering projects by integrating polygon features with elevation data.
• Assess climate change impacts on discontinuous permafrost by tracking changes in polygon boundaries over time.

Strengths

• Data originates from the authoritative Alberta Geological Survey Map 540.
• Provides vector polygon features specifically for permafrost analysis.
• Publicly released in standard GIS shapefile format for compatibility.

Limitations

• Specific row count, column names, and spatial resolution are unknown.
• The dataset is limited to a single map area (NTS 84N/SE), restricting broader regional analysis.
• Temporal coverage for the underlying geological mapping is not specified.
