These lake area estimates were produced using digital images from newly developed Planet Labs CubeSats, small satellites with a 4-band (blue, green, red, near-infrared) camera payload. In constellation, CubeSats collected imagery at very high spatial (3-5m) and temporal (near-daily) resolution. From the imagery, each lake's mean, minimum, and maximum areas and seasonal dynamism were derived. The dataset covers four Arctic-Boreal regions: the Yukon Flats Basin (YFB) in eastern interior Alaska, and the Mackenzie River Valley (MRV), Canadian Shield Transect (CST), and Hudson Bay Lowland (HBL) in Canada.", "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/C2162186248-ORNL_CLOUD.iso19115", "format": "ISO", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "downloadURL": "https://above.nasa.gov", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://daac.ornl.gov/ABOVE/guides/CubeSat_Arctic_Boreal_LakeArea_Fig1.png", "format": "PNG", "mediaType": "image/png"}, {"@type": "dcat:Distribution", "downloadURL": "https://data.ornldaac.earthdata.nasa.gov/protected/bundle/CubeSat_Arctic_Boreal_LakeArea_1667.zip", "format": "ZIP", "mediaType": "application/zip"}, {"@type": "dcat:Distribution", "downloadURL": "https://data.ornldaac.earthdata.nasa.gov/public/above/CubeSat_Arctic_Boreal_LakeArea/comp/ABoVE_grid_level_C_tile_IDs.csv", "format": "CSV", "mediaType": "text/csv"}, {"@type": "dcat:Distribution", "downloadURL": "https://data.ornldaac.earthdata.nasa.gov/public/above/CubeSat_Arctic_Boreal_LakeArea/comp/CubeSat_Arctic_Boreal_LakeArea.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://data.ornldaac.earthdata.nasa.gov/public/above/CubeSat_Arctic_Boreal_LakeArea/comp/CubeSat_Buffered_Mask_Tiles.kmz", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://doi.org/10.3334/ORNLDAAC/1667", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "https://search.earthdata.nasa.gov/search/granules?p=C2162186248-ORNL_CLOUD", "format": "BIN", "mediaType": "application/octet-stream"}], "identifier": "10.3334/ORNLDAAC/1667", "keyword": ["earth-science-ecosystems-biosphere-terrestrial-ecosystems", "earth-science-surface-water-terrestrial-hydrosphere-surface-water-features", "earth-science-surface-water-terrestrial-hydrosphere-surface-water-processes-measurements"], "license": "https://www.usa.gov/government-works", "modified": "2026-06-23", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "ORNL_DAAC"}, "spatial": "[\"CARTESIAN\", [{\"WestBoundingCoordinate\": -149.699, \"NorthBoundingCoordinate\": 70.3105, \"EastBoundingCoordinate\": -89.8193, \"SouthBoundingCoordinate\": 52.8149}]]", "temporal": "2017-05-01/2017-10-01", "theme": ["Earth Science"], "title": "Timeseries of Arctic-Boreal Lake Area Derived from CubeSat Imagery, 2017"}
