Digital Bedrock Geologic Map of Pilot Mountain Quadrangle, Tennessee

A GIS-based digital bedrock geologic map of the Pilot Mountain Quadrangle in Tennessee, adapted from a 1985 Tennessee Division of Geology source map. The dataset is provided by the National Park Service's Geologic Resources Inventory program and includes data layers, ancillary information, and unit descriptions. It is available in multiple GIS formats including an ESRI file geodatabase and an OGC geopackage.

Use Cases

• Conducting geologic mapping and analysis based on the bedrock unit layers.
• Integrating geologic data with other GIS layers for environmental planning based on the geospatial format.
• Studying regional bedrock geology for research or education based on the provided unit descriptions.

Strengths

• Data is provided in multiple standard GIS formats (ESRI file geodatabase, OGC geopackage).
• Includes supporting documentation like geologic unit descriptions and a user-friendly FAQ.
• Based on a source map with a defined scale of 1:24,000.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Based on the source map scale, features have a stated horizontal locational accuracy of 12.2 meters (40 feet).
