MCD12Q1 Version 6 以年为间隔的全球地表覆盖类型分布(2001-2018), 从User Guide获得了六种不同的分类方案,产品通过对MODIS Terra and Aqua 监督和分类反射率数据.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 Versio 6 Hierarchical Data Format 4 (HDF4) file.
The Terra and Aqua combined MODIS Land Cover Climate Modeling Grid (CMG) (MCD12C1) Version 6 数据产品是 MCD12Q1 Version 6 数据产品的空间降采样和重投影产品. 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 2018. 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.
MCD12Q2 v006:MODIS/Terra and Aqua Land Cover Dynamics Yearly L3 Global 500 m SIN Grid (2001-2017)
MCD12Q2 Version 6 数据产品提供以年为间隔的2001-2017年之间全球地表物候指标,该产品获取自 2-band Enhanced Vegetation Index (EVI2) (计算自 MODIS Nadir Bidirectional Reflectance Distribution Function (BRDF)-Adjusted Reflectance (NBAR).)的时间序列影像。 Vegetation phenology metrics at 500 meter spatial resolution are identified for up to two detected growing cycles per year. For pixels with more than two valid vegetation cycles, the data represent the two cycles with the largest NBAR-EVI2 amplitudes.
Provided in each MCD12Q2 Version 6 Hierarchical Data Format 4 (HDF4) file are layers for the total number of vegetation cycles detected for the product year, the onset of greenness, greenup midpoint, maturity, peak greenness, senescence, greendown midpoint, dormancy, EVI2 minimum, EVI2 amplitude, integrated EVI2 over a vegetation cycle, as well as overall and phenology metric-specific quality information. A low-resolution browse image showing greenup is also available when viewing each MCD12Q2 granule. SDS layers may be multi-dimensional with up to two valid vegetation cycles.
For areas where the NBAR-EVI2 values are missing due to cloud cover or other reasons, the data gaps are filled with good quality NBAR-EVI2 values from the year directly preceding or following the product year.
The Global Land Cover dataset - This is the harmonisation of all the regional products, into a full resolution global product, with a generalised legend.
Regional Land Cover datasets - The classification of these windows have been produced by regional GLC2000 partners, with a regionally specific legend, to provide as much detail as possible.

fromglc10 glc10v01的意思是global land cover 10年的v1版本 分类方式,就是按照这个标准进行土地覆盖分类。
