GLC_FCS10: global 10 m land-cover dataset with fine classification system from Sentinel-1 and 2 time-series data

Land cover is an indispensable basic data for the global carbon and water cycle, climate change research, ecological monitoring and food security assessment. Although the global 10 m land-cover products have made a lot progresses over past few years, their simple classification system is difficult to meet the needs of diverse applications.GLC_FCS10 is a novel global 10 m land cover product in 2023 generated from time-series Sentinel-1 and 2 imageries, it contains 30 fine land-cover types and achieves an overall accuracy of 83.16% and kappa coefficient of 0.789 using the globally distributed validation points. The specific description can be found at the corresponding algorithm article.

土地覆盖（Land cover）是全球碳水循环、气候变化研究、生态监测与粮食安全评估不可或缺的基础数据。尽管近年间全球10米分辨率土地覆盖产品已取得诸多进展，但其分类体系较为单一，难以满足多样化的应用需求。
GLC_FCS10是2023年发布的一款新型全球10米分辨率土地覆盖产品，基于时序哨兵1号（Sentinel-1）与哨兵2号（Sentinel-2）影像生成，包含30种精细土地覆盖类型；依托全球分布式验证样本点测算，其总体精度达83.16%，Kappa系数为0.789。该产品的详细技术说明可参阅相关算法研究论文。
