Digital Geologic-GIS Map of Wetherill Mesa Quadrangle, Colorado

A digital geologic-GIS map of the Wetherill Mesa Quadrangle in Colorado, adapted from a 1999 National Park Service geologic map. The dataset includes GIS data layers and tables available in file geodatabase and geopackage formats, along with ancillary PDF documents containing unit descriptions and metadata. It was produced by the National Park Service's Geologic Resources Inventory program.

Use Cases

• Conduct geologic unit analysis based on the provided geologic unit descriptions and GIS layers.
• Perform spatial analysis of geologic features like faults and contacts within the Wetherill Mesa quadrangle.
• Integrate geologic data into broader environmental or land management studies using the provided GIS formats.
• Verify and assess locational accuracy of geologic features for field studies, based on the stated map scale of 1:24,000.

Strengths

• Includes multiple GIS format options (file geodatabase, geopackage, shapefile) for compatibility with different software.
• Provides ancillary documentation (PDFs) with geologic unit descriptions and metadata for context.
• States a horizontal locational accuracy standard of 12.2 meters (40 feet) based on the 1:24,000 source map scale.

Limitations

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