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.471c9cb0-abfb-453d-b2a0-fe0be89f49dd.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_471c9cb0-abfb-453d-b2a0-fe0be89f49dd", "keyword": ["f08069 = Larimer", "f56001 = Albany", "field monitoring stations", "f56007 = Carbon", "magnetic field (earth)", "f08107 = Routt", "USGS:471c9cb0-abfb-453d-b2a0-fe0be89f49dd", "f08049 = Grand", "geophysics", "geospatial datasets", "aeromagnetic surveying", "f08057 = Jackson"], "modified": "2020-11-10T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-106.75961303711, 40.24494934082, -105.74485778809, 41.077007293701", "theme": ["geospatial"], "title": "Airborne geophysical survey: North Park"}
