AB  - &Emsp&Emsp; As the largest tributary of the Yellow River, the flow rate and sediment concentration of the Wei River have significant impacts on the Yellow River. Conducting spatiotemporal evolution monitoring of riverbanks is an important foundation for understanding hydrological changes in river basins.&Emsp& Emsp; This dataset is based on the high-resolution and resource satellite image data of the Gansu section of the main stream of the Wei River in 2008, 2015, and 2022. Through image orthorectified correction, image registration, image fusion, and mosaic cropping, combined with the image features of remote sensing images, interactive interpretation is used to extract the riverbank boundary of the Gansu section of the Wei River, including the Wei River management scope line, the Wei River waterfront boundary line, and the Wei River outer edge boundary line.&Emsp& Emsp; The dataset of the main stream shoreline of the Wei River can provide data support for hydrological dynamic monitoring and driving mechanism research in the Wei River Basin, and provide scientific decision-making basis for subsequent river lake shoreline protection and river ecological governance.
