Devonian Wabamun Group Isopach and Lithofacies GIS Data

1990s-era GIS shapefiles depict the thickness and rock composition of the Devonian Wabamun Group in the Western Canada Sedimentary Basin. The data was originally created by the Alberta Geological Survey and later edited for consolidation in 2005-2006. It represents a specific figure from the Geological Atlas of the Western Canada Sedimentary Basin.

Use Cases

• Analyze isopach polygon features to map variations in rock layer thickness across the basin.
• Study lithofacies polygon features to understand the distribution of different rock types and depositional environments.
• Integrate the shapefile data with other geological layers for regional subsurface modeling and resource assessment.
• Use the attributed polygon features for quantitative spatial analysis of Devonian sedimentary units.

Strengths

• Data is part of an authoritative reference volume, the Geological Atlas of the Western Canada Sedimentary Basin.
• Polygon features were consolidated and attributed into single files by feature type for usability.

Limitations

• Original digital files were created in the mid-1990s, potentially using outdated methodologies.
• Specific row counts, column details, and sample data are unavailable for assessment.
• The data's spatial accuracy is dependent on the source materials from the 1990s.
