Winterburn Group Depositional Elements Map for Western Canada Basin

Winterburn Group Depositional Elements and Index Map is a GIS dataset of line features representing Devonian geological formations. It was created by the Alberta Geological Survey in the mid-1990s and later edited in 2005-2006. The data is part of the Geological Atlas of the Western Canada Sedimentary Basin.

Use Cases

• Analyze spatial relationships between depositional element line features to model paleoenvironments.
• Integrate these line features with other geological map layers from the Atlas for basin-scale analysis.
• Use the attributed line data to categorize and study different Winterburn Group depositional systems.

Strengths

• Data is consolidated into single files by feature type, improving usability.
• Derived from authoritative source materials created by a provincial geological survey.

Limitations

• Original digital files were created in the mid-1990s, potentially using outdated methods.
• Specific row counts and spatial accuracy metrics for the line features are not provided.

Collection Method

Shapefiles produced from archived digital files, then edited to correct, attribute, and consolidate.

Time Range

Geological time range is the Devonian period. Data creation period is mid-1990s to 2005-2006.

Freshness

Last updated on the platform in March 2026, though the underlying data is from 2005-2006 edits of 1990s files.
