Digital Geologic-GIS Map of the 39-Mile Reach of Missouri National Recreational River and

Nebraska and South Dakota's 39-mile reach of the Missouri National Recreational River is mapped in this digital geologic-GIS dataset from the National Park Service. The data includes GIS layers and tables in multiple formats, such as a file geodatabase, OGC geopackage, and KMZ for Google Earth, and is supported by ancillary documents with geologic unit descriptions. It was produced by the NPS Geologic Resources Inventory program, adapted from a 2019 University of Nebraska-Lincoln source map.

Use Cases

• Visualizing regional geology in Google Earth based on the provided KMZ/KML files
• Conducting spatial analysis of geologic units using the GIS data layers and tables
• Referencing detailed geologic unit descriptions from the ancillary map information document

Strengths

• Data is available in multiple GIS formats, including a file geodatabase, OGC geopackage, and KMZ/KML
• Includes supporting project files for ArcGIS Pro, ArcMap, and QGIS software
• Ancillary documents provide geologic unit descriptions and map information

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• The KMZ/KML format version is limited in data layers presented and access to ancillary table information
• Row count is unknown, which may limit suitability assessment
