Devonian-Mississippian Petroleum System Polygon Overlay Features

A GIS dataset of polygon overlay features representing the Devonian-Mississippian petroleum system within the Western Canada Sedimentary Basin. The data was created by the Alberta Geological Survey in the mid-1990s and later edited and attributed in 2005-2006. It is part of a geological atlas chapter on petroleum generation and migration.

Use Cases

• Map the spatial extent of the Devonian-Mississippian petroleum system using polygon boundaries.
• Analyze relationships between petroleum system polygons and other geological features from the atlas.
• Integrate attributed polygon data into basin-scale geospatial models for resource estimation.

Strengths

• Data is part of an authoritative geological atlas reference volume.
• Polygon features were consolidated and attributed into single files by type.

Limitations

• Original data is from the mid-1990s, potentially lacking recent discoveries.
• Specific row counts, column details, and sample data are unavailable for review.
