In surveys such as this one where the data were originally collected in digital form and not digitized from contour maps, the information we provide typically includes latitude, longitude, magnetic anomaly in nanoTeslas, and intermediate values used to derive the magnetic anomaly such as total magnetic field.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://mrdata.usgs.gov/magnetic/show-survey.php?id=AK_ak29", "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.1b4e52f4-6cd8-43c0-ad28-b3eec17fdfe8.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_1b4e52f4-6cd8-43c0-ad28-b3eec17fdfe8", "keyword": ["field monitoring stations", "magnetic field (earth)", "USGS:1b4e52f4-6cd8-43c0-ad28-b3eec17fdfe8", "geophysics", "geospatial datasets", "aeromagnetic surveying"], "modified": "2020-11-10T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-145.58500671387, 65.376998901367, -144.53099060059, 65.591003417969", "theme": ["geospatial"], "title": "Airborne geophysical survey: Circle Mining District"}
