Global River Morphology (GRM)

The Global River Morphology (GRM) map shows the global distribution of rivers and their channel belt deposits by morphology. The data are derived based on a VGG-19 modified CNN classifying 2020 Landsat-8 imagery at a 30m global resolution.全球河流地貌（Global River Morphology, GRM）图展示了全球范围内河流及其河道带沉积物的地貌分布情况。该数据集基于经改进的VGG-19卷积神经网络（Convolutional Neural Network, CNN）构建，通过对2020年Landsat-8卫星影像以30米的全球空间分辨率进行分类得到。
