Diffendal and others. The original map consists of a 1:250,000 scale map plate with a \u201cstack unit\u201d structure showing multiple overlying units, as well as several roughly 1:750,000 scale maps in an accompanying pamphlet showing bedrock geology and structure contours. To capture as much of this content as possible in a geodatabase, three \u201clayers\u201d are included in this database: 1) Overlay polygons showing Quaternary loess deposits (Qes) where they overlay older Quaternary units; 2) a layer (consisting of line and polygon feature classes) showing Quaternary and bedrock units as depicted on the published 1:250,000 scale map (with the exception of Qes as described above), 3) a \u201cbedrock\u201d layer (consisting of line and polygon feature classes), showing pre-Quaternary units. Vector data were created by a combination of exporting vectors from published PDF files and hand digitizing against georegistered images of the published map and associated pamphlet figures. Required fields and non-spatial tables were populated with data from the printed map and pamphlet. The spatial data are accompanied by non-spatial tables that describe the sources of geologic information, a description of geologic map units, a glossary of terms, and a Data Dictionary that duplicates the Entity and Attribute information contained in the metadata file.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9B9F0GL", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.630fb899d34e36012efa0994.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_630fb899d34e36012efa0994", "keyword": ["Cretaceous", "GeMS", "Geologic Map Schema", "NCGMP", "NGS", "National Cooperative Geologic Mapping Program", "National Geologic Synthesis Project", "Nebraska", "O'Neill", "Quaternary", "Tertiary", "US Geoframework Initiative", "USGI", "USGS:630fb899d34e36012efa0994", "geologic maps", "geoscientificInformation", "structure contours"], "modified": "2022-10-28T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-99.9973, 41.9536, -98.0082, 43.0457", "theme": ["geospatial"], "title": "Digital database of the previously published geologic map of the O'Neill 1x2 degree quadrangle, Nebraska"}
