Point Lookout Quadrangle Geologic Map in Colorado at 1:24,000 Scale

A digital geologic-GIS map of the Point Lookout Quadrangle in Colorado, composed of GIS data layers and tables. The dataset was produced by the National Park Service's Geologic Resources Inventory program, adapted from a 1999 source map by Griffitts. It is available in multiple GIS formats including a file geodatabase and an OGC geopackage.

Use Cases

• Conducting geologic unit analysis based on the provided geologic unit descriptions and GIS layers.
• Performing spatial analysis of geologic features like faults and contacts within the quadrangle.
• Integrating geologic data into broader environmental or land management studies for the National Park Service.
• Creating derivative maps or visualizations using the provided ArcGIS Pro and ArcMap files.

Strengths

• Data is provided in multiple standard GIS formats, including a file geodatabase and an OGC geopackage.
• Includes ancillary documentation such as geologic unit descriptions and a user-friendly FAQ metadata file.
• Based on a source map with a defined scale of 1:24,000, providing a known level of detail.

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.
• Users are cautioned that features have a locational accuracy of within 12.2 meters (40 feet) of their actual location.
