Bedrock Geology GIS Map of the Lancing Quadrangle, Tennessee at 1:24,000 Scale

Lancing Quadrangle, Tennessee is covered by a digital bedrock geologic map composed of GIS data layers and tables. The dataset was produced by the National Park Service Geologic Resources Inventory program, adapted from a 2015 University of Tennessee research group map. It is available in multiple GIS formats including an ESRI file geodatabase and an OGC geopackage.

Use Cases

• Conducting geologic unit analysis based on the bedrock geologic units layer
• Mapping structural features like faults and folds based on the dedicated GIS layers
• Creating geologic cross-sections based on the cross-section lines data
• Performing spatial analysis of geologic contacts and attitudes

Strengths

• Data is available in multiple standard GIS formats (ESRI file geodatabase, OGC geopackage)
• Includes ancillary documentation with geologic unit descriptions and metadata
• Source map scale of 1:24,000 provides a detailed base for analysis

Limitations

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