Permafrost Polygon Features for the Beatty Lake Map Area

Polygon features delineate permafrost zones within the Beatty Lake area of the National Topographic System map sheet 84M/NE. The Government of Alberta created this GIS data in ArcInfo format for public distribution. The dataset was last updated in March 2026.

Use Cases

• Classify terrain stability by analyzing permafrost polygon boundaries and their spatial relationships.
• Model permafrost extent for climate impact studies using the polygon feature geometry and attributes.
• Assess infrastructure development risks by overlaying permafrost polygon data with proposed project sites.
• Train geospatial ML models to identify permafrost features from other remote sensing data using this labeled polygon set.

Strengths

• Data is provided in multiple standard GIS formats (E00, shapefile) for compatibility.
• Covers a defined NTS map area (84M/NE), providing a complete spatial unit for analysis.
• Maintained by a government organization (Government of Alberta), suggesting authoritative sourcing.

Limitations

• Specific data volume (row/feature count) and attribute columns are not documented.
• The spatial coverage is limited to a single NTS map sheet, not a broader regional study.
