Calcareous Ostracod Cummings Paleogeography Line Features

GIS line features illustrate the calcareous, ostracod, and Cummings paleogeography of the Western Canada Sedimentary Basin. The data was produced by the Alberta Geological Survey from archived mid-1990s digital files and edited in 2005-06. It represents Figure 4 from Chapter 17 of the Geological Atlas of the Western Canada Sedimentary Basin.

Use Cases

• Analyze the spatial distribution of calcareous paleogeography line features to reconstruct ancient sedimentary environments.
• Compare ostracod paleogeography features with other fossil records to study paleoecology within the Western Canada Sedimentary Basin.
• Integrate Cummings paleogeography line data with other GIS layers from the Geological Atlas to model basin evolution.
• Use the attributed and consolidated line features for cartographic reproduction of the original Atlas figure in digital formats.

Strengths

• Data consolidated into single files by feature type and figure for easier use.
• Edited in 2005-06 to correct and attribute the original mid-1990s digital files.
• Part of a reference volume documenting the subsurface geology of a major sedimentary basin.

Limitations

• Original source data is from the mid-1990s, representing historical interpretations.
• Specific row counts, column names, and spatial extents are not provided in the description.
• Data is limited to line features from a single figure within a larger atlas.
