Users are encouraged to use the [MCD12Q1 Version 6.1](https://doi.org/10.5067/MODIS/MCD12Q1.061) data product. The Terra and Aqua combined Moderate Resolution Imaging Spectroradiometer (MODIS) Land Cover Type (MCD12Q1) Version 6 data product provides global land cover types at yearly intervals (2001-2020), derived from six different classification schemes listed in the User Guide. The MCD12Q1 Version 6 data product is derived using supervised classifications of MODIS Terra and Aqua reflectance data. The supervised classifications then undergo additional post-processing that incorporate prior knowledge and ancillary information to further refine specific classes. Layers for Land Cover Type 1-5, Land Cover Property 1-3, Land Cover Property Assessment 1-3, Land Cover Quality Control (QC), and a Land Water Mask are provided in each MCD12Q1 Version 6 Hierarchical Data Format 4 (HDF4) file. Known Issues * The \"units\" field is missing in the metadata, however, this information can be found in the table above or on page 5 of the User Guide. * Known issues are described on pages 3 and 4 of the User Guide. * For complete information about known issues please refer to the [MODIS/VIIRS Land Quality Assessment website](https://landweb.modaps.eosdis.nasa.gov/knownissue?sensor=MODIS&sat=TerraAqua&as=6). Improvements/Changes from Previous Version * Version 5 used five classification schemes whereas Version 6 uses six classification schemes, including an entirely new classification scheme based on the Land Cover Classification System (LCCS) from the Food and Agricultural Organization (FAO). * New gap-filled spectro-temporal features developed by applying smoothing splines to the Nadir Bidirectional Reflectance Distribution Function (BRDF)-Adjusted Reflectance (NBAR) time series. This change results in significant changes between land cover classifications in Version 5 and Version 6 data. * Algorithm used in Version 6 includes a post-processing Hidden Markov Model (HMM) that reduces spurious year-to-year variation in class labels. * Algorithm refinements were implemented in upstream MODIS data used as inputs, such as the cloud mask, surface reflectance, and NBAR data products. * The value of \"Water\" in the IGBP classification scheme has changed from \"0\" to \"17.\" * The data product should not be used to determine post-classification land cover change between years due to the uncertainty in the land cover labels for any one year. More information can be found on page 2 of the User Guide. * File size is smaller due to HDF internal compression.", "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/C2763289443-LPCLOUD.iso19115", "format": "ISO", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "downloadURL": "https://doi.org/10.5067/MODIS/MCD12Q1.006", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://e4ftl01.cr.usgs.gov/WORKING/BRWS/Browse.001/2020.07.30/BROWSE.MCD12Q1.A2019001.h08v05.006.2020212125659.1.jpg", "format": "JPEG", "mediaType": "image/jpeg"}, {"@type": "dcat:Distribution", "downloadURL": "https://ladsweb.modaps.eosdis.nasa.gov/filespec/MODIS/6/MCD12Q1", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://landweb.modaps.eosdis.nasa.gov", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://lpdaac.usgs.gov/documents/101/MCD12_User_Guide_V6.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://lpdaac.usgs.gov/documents/86/MCD12_ATBD.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://www.earthdata.nasa.gov/centers/lp-daac", "format": "BIN", "mediaType": "application/octet-stream"}], "identifier": "10.5067/MODIS/MCD12Q1.006", "keyword": ["earth-science-land-use-land-cover-land-surface-land-use-land-cover-classification"], "license": "https://www.usa.gov/government-works", "modified": "2026-05-11", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "LP DAAC;NASA/GSFC/SED/ESD/TISL/MODAPS"}, "spatial": "[\"CARTESIAN\",[{\"NorthBoundingCoordinate\":90,\"WestBoundingCoordinate\":-180,\"EastBoundingCoordinate\":180,\"SouthBoundingCoordinate\":-90}]]", "temporal": "2001-01-01/2020-12-31", "theme": ["Earth Science"], "title": "MODIS/Terra+Aqua Land Cover Type Yearly L3 Global 500m SIN Grid V006"}
