Global River Widths from Landsat (GRWL)
收藏资源简介:
This is a novel dataset, called 'Global River Widths from Landsat', which characterizes the global coverage of rivers and streams. This Database is the first global compilation of river planform geometry. It contains planform measurements of >2.1 million km (>58 million measurements) of rivers ≥30 m wide at mean annual discharge. It also contains >7.6 million flagged measurements of lakes, reservoirs, and canals connected to the fluvial network. The dataset can be used for fluviogeomorphological changes associated to climate change.
本数据集为一款新型科研数据集,命名为全球Landsat河道宽度数据集(Global River Widths from Landsat),旨在刻画全球河流与溪流的覆盖格局。作为全球首份河流平面形态几何特征的汇编数据集,其包含年平均径流量条件下、宽度≥30米的河流共计超210万千米的平面形态测量数据,对应超5800万次独立测量结果。此外,数据集还收录了与河网相连的湖泊、水库及人工渠道共计超760万条带标注测量数据。该数据集可用于开展与气候变化相关的河流地貌变化研究。
