Bedrock Geology GIS Map of Jones Knob Quadrangle, Tennessee at 1:24,000 Scale

A National Park Service digital geologic map for the Jones Knob Quadrangle, adapted from a 1965 Tennessee Division of Geology source. The dataset includes GIS layers, tables, and ancillary documents like unit descriptions and a metadata FAQ. Data locational accuracy is within 12.2 meters horizontally, based on the original 1:24,000 map scale.

Use Cases

• Conducting geologic unit analysis based on the provided geologic unit descriptions and GIS layers.
• Creating derivative geologic maps for the Jones Knob area using the provided ESRI file geodatabase or geopackage formats.
• Assessing locational accuracy of geologic features for planning purposes based on the documented 12.2-meter standard.
• Integrating bedrock geology data into regional models using the provided geologic contacts and units layers.

Strengths

• Includes ancillary PDF documents with geologic unit descriptions and map information.
• Data is available in multiple GIS formats, including an ESRI file geodatabase and an OGC geopackage.
• Horizontal locational accuracy is explicitly defined as within 12.2 meters (40 feet).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The core source map is from 1965, which may not reflect recent geologic interpretations.
• Row count and dataset size are unknown, which may limit suitability assessment.
