Data users are encouraged to transition to the equivalent [VJ203MODLL](https://doi.org/10.5067/VIIRS/VJ203MODLL.021) (primary) or [VJ103MODLL](https://doi.org/10.5067/VIIRS/VJ103MODLL.021) (secondary) data products.\n\nThe Visible Infrared Imaging Radiometer Suite (VIIRS) Moderate Resolution Terrain Correction Geolocation (VNP03MODLL) Version 2 product from the NASA/NOAA Suomi National Polar-orbiting Partnership (Suomi NPP) VIIRS sensor is produced in 6 minute temporal satellite increments (swaths) at 750 meter resolution.  Intersecting the VIIRS line of sight vector with Earth’s geoid and the World Geodetic System (WGS) ellipsoid, this product is based on the SRTM30 Version 2 digital elevation model (DEM), which uses GTOPO30 data for areas from 60° North to 60° South. VNP03MODLL is a terrain correction geolocation product that provides the spatial location for various VIIRS data products.  Each swath of data is approximately 3,060 kilometers along track (long) and 3,060 kilometers across track (wide). \n\nProvided in the VNP03MODLL product are layers for height, latitude, and longitude. \n\nThese Science Data Sets (SDS) layers / Variables are used in conjunction with the [VNP14](https://doi.org/10.5067/viirs/vnp14.002) swath product for accurate geolocation information.\n\nKnown Issues\n\n* For complete information about known issues please refer to the [MODIS/VIIRS Land Quality Assessment website](https://landweb.modaps.eosdis.nasa.gov/knownissue?sensor=VIIRS).","stac_version":"1.0.0","stac_extensions":["https://stac-extensions.github.io/storage/v2.0.0/schema.json"],"extent":{"spatial":{"bbox":[[-180,-90,180,90]]},"temporal":{"interval":[["2012-01-17T00:00:00.000Z",null]]}},"assets":{"nasa":{"href":"https://search.earthdata.nasa.gov/search/granules?p=C2545310947-LPCLOUD","title":"Direct Download","description":"Earthdata Search allows users to search, discover, visualize, refine, and access NASA Earth Observation data.","roles":["data"]},"provider_metadata":{"href":"https://doi.org/10.5067/VIIRS/VNP03MODLL.002","title":"Provider Metadata","description":"The LP DAAC product page provides information on Science Data Set layers and links for user guides, ATBDs, data access, tools, customer support, etc.","roles":["metadata"]},"s3_lp_prod_protected_VNP03MODLL_002":{"href":"s3://lp-prod-protected/VNP03MODLL.002","roles":["data"],"title":"lp_prod_protected_VNP03MODLL_002","storage:refs":["aws"]},"s3_lp_prod_public_VNP03MODLL_002":{"href":"s3://lp-prod-public/VNP03MODLL.002","roles":["data"],"title":"lp_prod_public_VNP03MODLL_002","storage:refs":["aws"]},"s3_credentials":{"href":"https://data.lpdaac.earthdatacloud.nasa.gov/s3credentials","title":"S3 credentials API endpoint","roles":["metadata"]},"s3_credentials_documentation":{"href":"https://data.lpdaac.earthdatacloud.nasa.gov/s3credentialsREADME","title":"S3 credentials API endpoint documentation","roles":["metadata"]},"metadata":{"href":"https://cmr.earthdata.nasa.gov/search/concepts/C2545310947-LPCLOUD.xml","title":"CMR XML metadata for C2545310947-LPCLOUD","type":"application/xml","roles":["metadata"]}},"providers":[{"name":"LPCLOUD","roles":["producer"]},{"name":"NASA EOSDIS","roles":["host"]}],"links":[{"rel":"self","href":"https://cmr.earthdata.nasa.gov/stac/LPCLOUD/collections/VNP03MODLL_002","type":"application/json"},{"rel":"root","href":"https://cmr.earthdata.nasa.gov/stac","type":"application/json","title":"Root Catalog"},{"rel":"parent","href":"https://cmr.earthdata.nasa.gov/stac/LPCLOUD/collections","type":"application/json","title":"Provider Collections"},{"rel":"license","href":"https://www.earthdata.nasa.gov/engage/open-data-services-software-policies/data-use-guidance","title":"EOSDIS Data Use Policy","type":"text/html"},{"rel":"about","href":"https://cmr.earthdata.nasa.gov/search/concepts/C2545310947-LPCLOUD.html","title":"HTML metadata for collection","type":"text/html"},{"rel":"via","href":"https://cmr.earthdata.nasa.gov/search/concepts/C2545310947-LPCLOUD.native","title":"Native metadata for collection","type":"application/xml"},{"rel":"via","href":"https://cmr.earthdata.nasa.gov/search/concepts/C2545310947-LPCLOUD.echo10","title":"ECHO10 metadata for collection","type":"application/echo10+xml"},{"rel":"via","href":"https://cmr.earthdata.nasa.gov/search/concepts/C2545310947-LPCLOUD.json","title":"CMR JSON metadata for collection","type":"application/json"},{"rel":"via","href":"https://cmr.earthdata.nasa.gov/search/concepts/C2545310947-LPCLOUD.umm_json","title":"CMR UMM_JSON metadata for collection","type":"application/vnd.nasa.cmr.umm+json"},{"rel":"items","href":"https://cmr.earthdata.nasa.gov/stac/LPCLOUD/collections/VNP03MODLL_002/items","type":"application/geo+json","title":"Collection Items"}],"license":"CC0-1.0","keywords":["EARTH SCIENCE","SPECTRAL/ENGINEERING","SENSOR CHARACTERISTICS","GEOLOCATION"],"summaries":{"platform":["Suomi-NPP"],"instruments":["VIIRS"]},"storage:schemes":{"aws":{"type":"aws-s3","platform":"https://{bucket}.s3.{region}.amazonaws.com","bucket":"lp-prod-protected","region":"us-west-2"}}}
