    "abstract": "These data are a copy of MODIS data from the NASA Level-1 and Atmosphere Archive & Distribution System (LAADS) Distributed Active Archive Center (DAAC). The copy is potentially only a subset. Below is the description from https://ladsweb.modaps.eosdis.nasa.gov/missions-and-measurements/products/MCD12Q1\n\n\n\n\n\nThe MODIS Land Cover Type product contains multiple classification schemes, which describe land cover properties derived from observations spanning a year's input of Terra and Aqua data. The primary land cover scheme identifies 17 land cover classes defined by the International Geosphere Biosphere Programme (IGBP), which includes 11 natural vegetation classes, 3 developed and mosiacked land classes, and three non-vegetated land classes.\n\nThe MODIS Terra + Aqua Land Cover Type Yearly L3 Global 500 m SIN Grid product incorporates five different land cover classification schemes, derived through a supervised decision-tree classification method:\n\nLand Cover Type 1: IGBP global vegetation classification schemeLand Cover Type 2: University of Maryland (UMD) schemeLand Cover Type 3: MODIS-derived LAI/fPAR schemeLand Cover Type 4: MODIS-derived Net Primary Production (NPP) schemeLand Cover Type 5: Plant Functional Type (PFT) scheme\n\nAdditional layers include a Land Cover Type Assessment SDS, a Land Cover Percent SDS, and a Land Cover Quality Control SDS.\n\nCollection 5.1 Land Cover Type products are produced with revised training data and certain algorithm refinements.
