In the earlier days of surveying, the only way to represent this data was to generate an analog map with contour lines. This dataset is a representation of the digitized contour lines either by following the lines or by choosing the intersection of the contour and flight-line to create a value of the magnetic field. The values presented are latitude, longitude, and map magnetic-field values.", "distribution": [{"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.a0a2d52d-1f4b-4e1c-a9b2-5968ffd78c72.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_a0a2d52d-1f4b-4e1c-a9b2-5968ffd78c72", "keyword": ["USGS:a0a2d52d-1f4b-4e1c-a9b2-5968ffd78c72", "aeromagnetic surveying", "f26053 = Gogebic", "f26131 = Ontonagon", "f55125 = Vilas", "field monitoring stations", "geophysics", "geospatial datasets", "magnetic field (earth)"], "modified": "2020-11-10T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-89.502082824707, 46.111309051514, -88.999069213867, 46.990825653076", "theme": ["geospatial"], "title": "Airborne geophysical survey: Michigan Coop South '63"}
