2020年全球地表覆盖产品数据集

该数据集为2020年全球1km地表覆盖年度产品。产品以国产风云卫星和MODIS协同生产的时间序列地表反射率产品为基础数据，以现有的2020年高分辨率全球地表覆盖分类产品构建初始样本集，利用随机森林模型，通过全球地理分区、样本迁移和模型迁移的方法生产得到，直接验证精度为90.78%。

This dataset is the annual 1km global land cover product for 2020. It is developed based on time-series surface reflectance products jointly produced by domestically developed Fengyun satellites and MODIS. An initial sample set was constructed using existing high-resolution global land cover classification products from 2020, and the final product was generated via a random forest model through three core workflows: global geographic zoning, sample transfer, and model transfer. Its direct validation accuracy reaches 90.78%.
