We are in the process of migrating all NASA Earth science data sites into Earthdata from now until end of 2026. Not all NASA Earth science data and resources will appear here until then. Thank you for your patience as we make this transition.Read about the Web Unification Project
Description
The MCD12C1 Version 6 data product was decommissioned on July 31, 2023. Users are encouraged to use the MCD12C1 Version 6.1 data product.
The Terra and Aqua combined Moderate Resolution Imaging Spectroradiometer (MODIS) Land Cover Climate Modeling Grid (CMG) (MCD12C1) Version 6 data product provides a spatially aggregated and reprojected version of the tiled MCD12Q1 Version 6 data product. Maps of the International Geosphere-Biosphere Programme (IGBP), University of Maryland (UMD), and Leaf Area Index (LAI) classification schemes are provided at yearly intervals at 0.05 degree (5,600 meter) spatial resolution for the entire globe from 2001 to 2020. Additionally, sub-pixel proportions of each land cover class in each 0.05 degree pixel is provided along with the aggregated quality assessment information for each of the three land classification schemes.
Provided in each MCD12C1 Version 6 Hierarchical Data Format 4 (HDF4) file are layers for Majority Land Cover Type 1-3, Majority Land Cover Type 1-3 Assessment, and Majority Land Cover Type 1-3 Percent.
Known Issues
Known issues are described on pages 3 and 4 of the User Guide.
The following changes and improvements were implemented for inputs to MODIS Version 6 land cover products: (1) Updated to include the improvements and changes made for the MCD12Q1 Version 6 data product, (2) Version 6 does not include a Majority Land Cover Type Quality Control (QC) Layer, (3) Land_Cover_Type_Percent_1, Land_Cover_Type_Percent_2, Land_Cover_Type_Percent_3 layers have up to 17 dimensions and include the sub-pixel proportions of the IGBP, UMD, and LAI classes in each 0.05 degree pixel, (4) The IGBP classification scheme legend used differs from the legend used for the MCD12Q1 Version 6 data product and can be found on page 16 of the User Guide, and (5) 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.
