Digital Geologic-GIS Map of the Bell Farm Quadrangle, Kentucky

The Digital Geologic-GIS Map of the Bell Farm Quadrangle and parts of the Barthell SW Quadrangle, Kentucky is composed of GIS data layers and tables. It was produced by the National Park Service Geologic Resources Inventory program, adapted from source maps by the Kentucky Geological Survey and U.S. Geological Survey. The dataset includes geodatabase and geopackage formats, layer files, and ancillary PDF documentation.

Use Cases

• Conducting geologic analysis based on the provided GIS data layers and geologic unit descriptions.
• Creating custom geologic maps using the included ArcGIS Pro or ArcMap files.
• Integrating park-specific geologic data into regional models based on the 1:24,000 scale source maps.
• Studying geologic contacts and observation localities referenced in the platform tags.

Strengths

• Data is available in multiple GIS formats including a 10.1 file geodatabase and an OGC geopackage.
• Includes comprehensive ancillary documentation such as geologic unit descriptions and a user-friendly FAQ metadata PDF.
• Based on source maps from authoritative institutions: the Kentucky Geological Survey and U.S. Geological Survey.

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.
• The description cautions about locational accuracy, noting features are within 12.2 meters horizontally based on map scale standards.
