Geologic studies in this region are hampered by a scarcity of bedrock exposures because of a nearly continuous blanket of unconsolidated sediments resulting from glaciation of the region during the Pleistocene ice ages. The USGS mapping, done largely at a scale of 1:24,000, routinely recorded the location and extent of exposed bedrock to provide both an indication of where direct observations were made and a guide for future investigations to expedite location of observable rock exposures. The locations of outcrops were generally shown as colored or patterned overlays on printed geologic maps. Although those maps have been scanned and are available as Portable Document Format (PDF) files, no further digital portrayal of the outcrops had been done. We have conducted a prototype study of digitizing and improving locational accuracy of the outcrop locations in parts of Dickinson County, Michigan, to form a data layer that can be used with other data layers in geographic information system applications.", "description": "Report: 3 p.; Data release", "publisher": {"@type": "Organization", "name": "U.S. Geological Survey"}, "author": [{"@type": "Person", "name": "Cannon, William F.", "givenName": "William F.", "familyName": "Cannon", "identifier": {"@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0002-2699-8118", "url": "https://orcid.org/0000-0002-2699-8118"}, "affiliation": [{"@type": "Organization", "name": "Eastern Mineral and Environmental Resources Science Center", "url": "https://www.usgs.gov/centers/geology-energy-and-minerals-science-center"}]}, {"@type": "Person", "name": "Schulte, Ruth", "givenName": "Ruth", "familyName": "Schulte", "identifier": {"@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0003-4724-5905", "url": "https://orcid.org/0000-0003-4724-5905"}, "affiliation": [{"@type": "Organization", "name": "National Minerals Information Center", "url": "https://www.usgs.gov/centers/national-minerals-information-center"}, {"@type": "Organization", "name": "Eastern Mineral and Environmental Resources Science Center", "url": "https://www.usgs.gov/centers/geology-energy-and-minerals-science-center"}]}, {"@type": "Person", "name": "Bickerstaff, Damon", "givenName": "Damon", "familyName": "Bickerstaff", "identifier": {"@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0003-0887-9761", "url": "https://orcid.org/0000-0003-0887-9761"}, "affiliation": [{"@type": "Organization", "name": "Eastern Mineral and Environmental Resources Science Center", "url": "https://www.usgs.gov/centers/geology-energy-and-minerals-science-center"}]}], "funder": [{"@type": "Organization", "name": "Eastern Mineral and Environmental Resources Science Center", "url": "https://www.usgs.gov/centers/geology-energy-and-minerals-science-center"}], "spatialCoverage": [{"@type": "Place", "additionalType": "country", "name": "United States", "url": "https://geonames.org/6252001"}, {"@type": "Place", "additionalType": "state", "name": "Michigan", "url": "https://geonames.org/5001836"}, {"@type": "Place", "additionalType": "state", "name": "Wisconsin", "url": "https://geonames.org/5279468"}, {"@type": "Place", "additionalType": "state", "name": "Dickinson County", "url": "https://geonames.org/4990845"}, {"@type": "Place", "additionalType": "state", "name": "Florence County", "url": "https://geonames.org/5253306"}, {"@type": "Place", "additionalType": "state", "name": "Iron County", "url": "https://geonames.org/4997220"}, {"@type": "Place", "additionalType": "state", "name": "Marinette County", "url": "https://geonames.org/5261856"}, {"@type": "Place", "geo": [{"@type": "GeoShape", "additionalProperty": {"@type": "PropertyValue", "name": "GeoJSON", "value": {"type": "FeatureCollection", "features": [{"type": "Feature", "properties": {}, "geometry": {"type": "Polygon", "coordinates": [[[-88.1333, 45.75], [-87.7, 45.75], [-87.7, 46.1], [-88.1333, 46.1], [-88.1333, 45.75]]]}}]}}}, {"@type": "GeoCoordinates", "latitude": 45.925000000000004, "longitude": -87.91664999999999}]}]}
