Digital Geologic Map of Fork Ridge Quadrangle, Tennessee at 1:24,000 Scale

A National Park Service Geologic Resources Inventory digital map of the Tennessee part of the Fork Ridge Quadrangle. The dataset includes GIS layers, tables, and ancillary documents, adapted from a 1991 Tennessee Division of Geology source map. Data formats include a file geodatabase, geopackage, and shapefiles, with locational accuracy within 12.2 meters based on the original 1:24,000 scale.

Use Cases

• Analyze geologic unit distributions based on the provided GIS data layers.
• Model subsurface structures based on the included faults and folds data.
• Conduct spatial analysis for resource management based on the geologic contacts and attitude observations.
• Integrate geologic data with other environmental layers based on the geodatabase format.

Strengths

• Includes multiple GIS formats (file geodatabase, geopackage, shapefile) for compatibility with various software.
• Provides ancillary PDF documents with geologic unit descriptions and metadata.
• Locational accuracy is specified as within 12.2 meters horizontally based on the 1:24,000 source map scale.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific quadrangle and source map.
