Digital Geologic-GIS Map of the Barthell SW Quadrangle, Tennessee

A digital geologic-GIS map of parts of the Barthell SW Quadrangle in Tennessee, adapted from a 2016 Tennessee Division of Geology source map. The dataset is composed of GIS data layers and tables available in multiple formats, including a file geodatabase and OGC geopackage. It was completed as part of the National Park Service's Geologic Resources Inventory program.

Use Cases

• Conducting spatial analysis of geologic units based on the provided GIS layers.
• Creating derivative maps for park management based on the geologic unit descriptions.
• Assessing locational accuracy of geologic features based on the documented 1:24,000 source map scale.

Strengths

• Data is available in multiple GIS formats, including a 10.1 file geodatabase and an OGC geopackage.
• Includes ancillary documents with geologic unit descriptions and metadata.
• Source map scale of 1:24,000 is documented, providing a basis for accuracy assessment.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
