The mission was co-sponsored by the National Aeronautics and Space Administration (NASA) and National Geospatial-Intelligence Agency (NGA). NASA's Jet Propulsion Laboratory (JPL) performed preliminary processing of SRTM data and forwarded partially finished data directly to NGA for finishing by NGA's contractors and subsequent monthly deliveries to the NGA Digital Products Data Wharehouse (DPDW). All the data products delivered by the contractors conform to the NGA SRTM products and the NGA Digital Terrain Elevation Data (DTED) to the Earth Resources Observation & Science (EROS) Center. The DPDW ingests the SRTM data products, checks them for formatting errors, loads the SRTM DTED into the NGA data distribution system, and ships the public domain SRTM DTED to the U.S. Geological Survey (USGS) Earth Resources Observation & Science (EROS) Center.   \n\nTwo resolutions of finished grade SRTM data are available through EarthExplorer from the collection held in the USGS EROS archive:\n\n1 arc-second (approximately 30-meter) high resolution elevation data are only available for the United States.\n\n3 arc-second (approximately 90-meter) medium resolution elevation data are available for global coverage. The 3 arc-second data were resampled using cubic convolution interpolation for regions between 60\u00b0 north and 56\u00b0 south latitude.\n\n[Summary provided by the USGS.]", "distribution": [{"@type": "dcat:Distribution", "description": "Search results for publications that cite this dataset by its DOI.", "downloadURL": "https://scholar.google.com/scholar?q=10.5067%2FBA180DOW1E1Q", "format": "HTML", "mediaType": "text/html", "title": "Google Scholar search results"}, {"@type": "dcat:Distribution", "description": "Direct download via HTTPS protocol.", "downloadURL": "https://n5eil01u.ecs.nsidc.org/PRE_OIB/BLVIS2.001/", "format": "HTML", "mediaType": "text/html", "title": "Download this dataset"}, {"@type": "dcat:Distribution", "description": "NASA's newest search and order tool for subsetting, reprojecting, and reformatting data.", "downloadURL": "https://search.earthdata.nasa.gov/search/granules?p=C1397419923-NSIDC_ECS&m=61.61129042101072%21-37.57342970122993%211%210%210%210%2C2&q=BLVIS2", "format": "HTML", "mediaType": "text/html", "title": "Download this dataset through Earthdata Search"}, {"@type": "dcat:Distribution", "description": "Tool to visualize, search, and download IceBridge data.", "downloadURL": "https://nsidc.org/icebridge/portal/map", "format": "HTML", "mediaType": "text/html", "title": "Download this dataset"}, {"@type": "dcat:Distribution", "description": "Data Access link for ITSD project", "downloadURL": "https://nsidc.org/data/data-access-tool/BLVIS2/versions/1/", "format": "HTML", "mediaType": "text/html", "title": "Download this dataset"}, {"@type": "dcat:Distribution", "description": "Provides access to data, documentation, tools, citation information, support, and other resources.", "downloadURL": "https://doi.org/10.5067/BA180DOW1E1Q", "format": "HTML", "mediaType": "text/html", "title": "This dataset's landing page"}, {"@type": "dcat:Distribution", "description": "Includes a user's guide, supplemental documents like ATBDs and academic papers, How Tos, FAQs, etc.", "downloadURL": "https://doi.org/10.5067/BA180DOW1E1Q", "format": "HTML", "mediaType": "text/html", "title": "View documentation related to this dataset"}], "identifier": "C1220555800-USGS_LTA", "issued": "2000-02-01", "keyword": ["earth-science", "land-surface", "radar", "spectral-engineering", "topography"], "landingPage": "https://cmr.earthdata.nasa.gov:443/search/concepts/C1220555800-USGS_LTA.html", "language": ["en-US"], "modified": "2025-03-31", "programCode": ["026:001"], "publisher": {"@type": "org:Organization", "name": "DOI/USGS/EROS"}, "spatial": "-180.0 -56.0 180.0 60.0", "temporal": "2000-02-01T00:00:00Z/2000-02-29T23:59:59.999Z", "theme": ["SRTM", "geospatial"], "title": "Shuttle Radar Topography Mission DTED Level 1 (3-arc second) Data (DTED-1)"}
