English(EN) A Systematic Evaluation of the COTQ Provincial Land Cover Product: Structural Consistency, Spectral Separability, and Relative Positioning Against ESA, ESRI, and Google Products

新研究评估魁北克省COTQ土地覆盖产品与全球数据集的对比情况

一篇新的研究论文系统地评估了为魁北克省开发的COTQ省级土地覆盖产品,并将其与三个全球10米土地覆盖数据集进行了对比:ESA WorldCover、ESRI LandCover和Google DynamicWorld。该研究在通用图例下统一了这些产品,并采用结构指标、光谱可分性指标和航空摄影判读来分析它们的一致性和差异。结果表明,COTQ在结构和光谱上与ESA WorldCover最为相似,但在定义和优先级方面存在显著差异,尤其是在城市、湿地和岩石区域。 AI

影响 提供了对土地覆盖产品的详细比较,有助于选择和应用卫星衍生的数据进行环境监测和土地管理。
