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.本研究以渭河干流甘肃段 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、配准、融合、镶嵌和裁剪等处理,结合影像的图像特征,采用交互解译的方法提取渭河甘肃段河岸线边界,主要包括渭河管理范围线、渭河临水边界线、渭河外缘边界线.同时利用高精度无人机航测影像数据与影像底图数据上典型区域和重要标志物相结合,以保证河岸线提取的可靠性.本数据集可为渭河干流水文动态监测和驱动机制研究提供数据支撑,并为后续河湖岸线保护和河道生态治理提供科学决策依据.
A dataset of spatial changes of river shorelines in Gansu section of the Weihe River main stream(2008,2015,2022)
As the largest tributary of the Yellow River,the Weihe River has an important influence on the Yellow River in terms of both its flow and sediment load.Carrying out spatial and temporal evolution monitoring of the river shorelines is an important basis for grasping the hydrological changes of the river in the basin.In this study,we used the high-frequency and resource satellite image data of the Gansu section of the Weihe River in 2008,2015 and 2022 as the base map,and extracted the river shorelines of the Gansu section of the Weihe River through the processing of image ortho-correction,alignment,fusion,mosaicing and cropping;combining with the image characteristics of the image,we adopted the method of interactive deciphering,including the Weihe River management range line,the Weihe River waterfront boundary line,and the Weihe River outer edge boundary line.Additionally,high-precision UAV aerial image data were utilized,integrating typical areas and important markers on the image base map data to ensure the reliability of river shoreline extraction.This dataset can provide data support for studying the hydrological dynamic monitoring and driving mechanisms of the Weihe River main stream.Furthermore,it can serve as basis for making informed decisions regarding the protection of river and lake shorelines and the ecological management of the river.
