The HCI-III system consists of three different components. The first is an imaging spectrometer which collects reflectance data with a spatial resolution of approximately 500 nanometers (nm) for 514 spectral channels covering the 450-2,500 nm wavelength range of the electromagnetic spectrum (Martini and others, 2017). The second is a spectrally calibrated RGB camera that collects high resolution imagery of the samples with a 50 micrometer (\u03bcm) pixel size. The third component is a three-dimensional (3D) laser profiler that measures sample texture, surface features and shape with a vertical resolution of 20 \u03bcm (Martini and others, 2017).\nCorescan reflectance data were provided for a total of 63 hand samples and four billets analyzed using the HCI-III system in three scans.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/F7057DWM", "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.5a048975e4b0dc0b45b50689.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5a048975e4b0dc0b45b50689", "keyword": ["Alaska", "Alaska Range", "Bond Creek", "Canada", "ENVI", "Environment for Visualizing Images", "GGGSC", "Geology, Geophysics, and Geochemistry Science Center", "MRP", "Mineral Resources Program", "Nabesna", "Nabesna A-2 quadrangle", "Nabesna A-4 quadrangle", "Nabesna B-4 quadrangle", "Nikonda Creek", "Nutzotin Mountains", "Orange Hill", "SWIR", "USGS:5a048975e4b0dc0b45b50689", "VNIR", "Valdez-Cordova County", "Wrangell Mountains", "Wrangell\u2013Saint Elias National Preserve", "Yukon Territory", "economy", "geoscientificInformation", "hyperspectral imaging", "imaging spectroscopy", "infrared imaging", "mineral resources", "mineralogy", "remote sensing", "shortwave infrared", "spectroscopy", "visible-near infrared"], "modified": "2020-09-30T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-142.85154, 62.08211, -141.86813, 62.25573", "theme": ["geospatial"], "title": "Corescan\u00a9 hyperspectral reflectance data"}
