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

2021-10-10 09:32:19 作者：互联网

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.

MCD12Q1 V6产品提供了按年度（2001-2016年）的全球土地覆盖类型，由六种不同的分类方案得出。它是通过对MODIS Terra和Aqua反射率数据进行监督分类得出的。监督下的分类然后经过额外的后处理，结合先前的知识和辅助信息，进一步完善特定的类别。
