Digital Geologic-GIS Map of the Chattanooga Quadrangle, Tennessee

The Digital Geologic-GIS Map of the Chattanooga Quadrangle, Tennessee is a GIS dataset from the National Park Service Geologic Resources Inventory program. It is composed of GIS data layers and tables, available in file geodatabase and geopackage formats, adapted from a 1964 Tennessee Division of Geology quadrangle map. The data includes ancillary documents with geologic unit descriptions and metadata.

Use Cases

• Conduct geologic analysis and visualization based on the provided GIS data layers.
• Integrate geologic unit information into environmental models based on the included ancillary map information.
• Perform spatial queries on geologic features like faults and folds based on the GIS structure.
• Create derivative maps for land management or educational purposes based on the source map scale and accuracy standards.

Strengths

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

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Users are cautioned about locational accuracy; features are within 12.2 meters of their actual location.
