Google Earth Engine ——(2001-2016年)的全球土地覆盖类型/土地利用500m分辨率MODIS/006/MCD12Q1数据集

标签:Engine MODIS Google area cover least 60% dominated 2m


The MCD12Q1 V6 product provides global land cover types at yearly intervals (2001-2016) derived from six different classification schemes. It 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.
