渭河干流甘肃段河岸线空间变化数据集（2008、2015和2022年）

渭河作为黄河的最大支流，流量和含沙量对黄河均具有重要影响。开展河岸线时空演变监测是掌握流域内河道水文变化的重要基础。   该数据集以渭河干流甘肃段2008年、2015年和2022年三期的高分和资源卫星影像数据为底图，通过影像正射校正、影像配准、影像融合、镶嵌...

As the largest tributary of the Yellow River, the Wei River's runoff and sediment concentration exert critical impacts on the Yellow River. Monitoring the spatiotemporal evolution of riverbank lines serves as a fundamental basis for understanding hydrological variations of river channels within the Wei River basin.

This dataset employs three-phase Gaofen and Ziyuan satellite imagery data of the main stream of the Wei River in Gansu Province, acquired in 2008, 2015 and 2022, as the base map, and conducts processing procedures including orthorectification, image registration, image fusion, mosaic...
