The products include per-pixel latitude and longitude, surface height, solar and sensor zenith and azimuth angles, along with quality flags describing geolocation validity. In addition, scan-level timing, spacecraft attitude, and orbital navigation parameters are provided to support precise georeferencing and downstream processing. The GEO data are distributed in self-describing data formats and are intended to be used in conjunction with Level-1 radiance products to enable the generation and analysis of higher-level geophysical data products.", "distribution": [{"@type": "dcat:Distribution", "conformsTo": "http://www.isotc211.org/2005/gmi", "description": "The metadata's original source.", "downloadURL": "https://cmr.earthdata.nasa.gov/search/concepts/C1940926976-OB_DAAC.iso19115", "format": "ISO", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "downloadURL": "https://nasa.github.io/oceandata-notebooks/", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://oceancolor.gsfc.nasa.gov/files/obdaac-ancillary-data-sources.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://oceandata.sci.gsfc.nasa.gov/directdataaccess/Geo-Location/NOAA20-VIIRS/", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://search.earthdata.nasa.gov/search/granules?p=C1940926976-OB_DAAC", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://www.earthdata.nasa.gov/data/instruments/VIIRS", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://www.earthdata.nasa.gov/data/platforms/space-based-platforms/NOAA-20", "format": "BIN", "mediaType": "application/octet-stream"}], "identifier": "10.5067/NOAA-20/VIIRS/L1/GEO/2", "keyword": ["earth-science-geodetics-solid-earth", "earth-science-sensor-characteristics-spectral-engineering", "earth-science-sensor-characteristics-spectral-engineering-geolocation"], "license": "https://www.usa.gov/government-works", "modified": "2026-06-23", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "NASA/GSFC/SED/ESD/GCDC/OB.DAAC;OBPG"}, "spatial": "[\"CARTESIAN\", [{\"NorthBoundingCoordinate\": 90, \"EastBoundingCoordinate\": 180, \"SouthBoundingCoordinate\": -90, \"WestBoundingCoordinate\": -180}]]", "temporal": "2017-11-29/2026-06-15", "theme": ["Earth Science"], "title": "NOAA-20 VIIRS Level-1 Geolocation Data, version 2"}
