Bedrock Geology GIS Map of Oneida North Quadrangle, Tennessee at 1:24,000 Scale

National Park Service Geologic Resources Inventory data provides a digital bedrock geology map for parts of the Oneida North Quadrangle in Tennessee. The dataset is composed of GIS data layers and tables, adapted from a 2013 Tennessee Division of Geology source map. It includes multiple file formats for GIS software and ancillary documentation with geologic unit descriptions.

Use Cases

• Map bedrock geology units based on the provided geologic unit descriptions and GIS layers.
• Conduct spatial analysis of geologic features based on the included GIS data layers.
• Integrate geologic data into regional models based on the 1:24,000 source map scale.
• Create derivative maps for resource management based on the National Park Service GRI framework.

Strengths

• Includes multiple GIS formats (file geodatabase, geopackage, shapefile) for broad software compatibility.
• Provides ancillary PDF documents with geologic unit descriptions and metadata.
• Based on a source map with a defined scale of 1:24,000.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data locational accuracy is noted to be within 12.2 meters (40 feet) horizontally.
