Digital Geologic-GIS Map of the Moccasin Quadrangle, Colorado (1:24,000 Scale)

A digital geologic-GIS dataset for the Moccasin Quadrangle in Colorado, adapted from a 1999 National Park Service geologic map. The dataset is composed of GIS data layers and tables, available in multiple formats including a file geodatabase and an OGC geopackage. It was completed as part of the NPS Geologic Resources Inventory program and includes ancillary documents with geologic unit descriptions.

Use Cases

• Conducting geologic resource evaluations based on the included geologic unit descriptions and map information.
• Creating derivative maps and analyses using the provided GIS data layers for faults, contacts, and attitudes.
• Assessing locational accuracy for features in the Moccasin Quadrangle based on the stated 1:24,000 source map scale.

Strengths

• Includes multiple GIS format options (file geodatabase, OGC geopackage, shapefile) for compatibility with different software.
• Provides ancillary PDF documents with geologic unit descriptions and metadata for context.
• States a locational accuracy standard: features are within 12.2 meters (40 feet) horizontally based on the 1:24,000 source scale.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
