Permafrost Polygon Features for Slavey Creek Area

GIS polygon data depicts permafrost distribution within the Slavey Creek area of the Canadian Arctic (NTS 84N/SW). The dataset was created by the Government of Alberta for public distribution. It was last updated in March 2026.

Use Cases

• Classify permafrost presence/absence using polygon geometry and associated surficial geology attributes.
• Map terrain stability for infrastructure planning by analyzing the spatial distribution of permafrost features.
• Model ground ice content by joining polygon data with other regional geophysical or borehole datasets.
• Analyze surficial geology patterns in relation to permafrost extent using polygon feature attributes.

Strengths

• Data covers a defined National Topographic System (NTS) map sheet area (84N/SW).
• Available in multiple standard GIS formats (E00, shapefile) for interoperability.
• Maintained by a government authority (Government of Alberta) with a recent update in 2026.

Limitations

• Specific row count, column names, and attribute schema are not documented.
• The spatial coverage is limited to a single NTS map sheet, not a broader region.
• Sample data is unavailable to preview attribute fields and data structure.
