Digital Geologic-GIS Map of the Sharp Place Quadrangle, Tennessee

A 2026-updated digital geologic-GIS map for parts of the Sharp Place Quadrangle, Tennessee, created by the National Park Service Geologic Resources Inventory program. The dataset is adapted from a 2015 Tennessee Division of Geology geologic quadrangle map by Hoyal and Horton and includes GIS data layers, tables, and ancillary documentation. It is available in multiple GIS formats including a file geodatabase and an OGC geopackage.

Use Cases

• Conduct geologic resource evaluation based on the included geologic unit descriptions and map information.
• Perform spatial analysis of geologic features like contacts and cross-sections using the provided GIS data layers.
• Integrate geologic data into park management plans using the standardized GRI digital format.
• Assess locational accuracy of geologic features for field studies based on the stated 1:24,000 source map scale.

Strengths

• Data is provided in multiple standard GIS formats, including an OGC geopackage and an ESRI file geodatabase.
• Includes comprehensive ancillary documents: a GIS readme, geologic unit descriptions, and a user-friendly FAQ metadata file.
• Source map scale of 1:24,000 provides a defined level of detail for the geologic features.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Users are cautioned that features have a horizontal locational accuracy of within 12.2 meters (40 feet) of their actual location.
• Row count and dataset size are unknown, which may limit suitability assessment.
