"一带一路"沿线区域沙漠沙脊线数据集（2000-2020年）

本数据集基于Landsat遥感影像，通过辐射定标和大气校正等预处理算法得到沙漠区域影像，通过人工目视解译的方法提提取沙漠区域中的沙脊线。数据集涉及的沙漠主要包括塔克拉玛干沙漠、 古尔班通古特沙漠（准噶尔盆地沙漠）、巴丹吉林沙漠、腾格里沙漠、库木塔格沙漠、柴达木盆地沙漠、库布齐沙漠、乌...

This dataset is constructed using Landsat remote sensing imagery. Preprocessing steps including radiometric calibration and atmospheric correction were employed to derive desert region images, followed by the extraction of sand ridge lines within these desert areas through manual visual interpretation. The deserts included in this dataset mainly comprise the Taklimakan Desert, Gurbantunggut Desert (Junggar Basin Desert), Badain Jaran Desert, Tengger Desert, Kumtag Desert, Qaidam Basin Desert, Kubuqi Desert, and the W...
