"一带一路"沿线区域沙漠分布及面积数据集（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，通过人工目视解译及波段指数的方法提提取沙漠边界区域。数据集涉及的沙漠主要包括"一带一路"沿线区域主要沙漠。分别为腾格里沙漠，塔克拉马干沙漠，巴丹吉林沙漠，库布奇沙漠，乌兰布和沙漠，库木塔格沙漠，古...

This dataset is constructed using Landsat remote sensing imagery. Preprocessing operations including radiometric calibration and atmospheric correction were first applied to generate desert region images, followed by the extraction of desert boundary areas through manual visual interpretation and band index-based methods. The covered deserts primarily refer to the major deserts along the Belt and Road Initiative routes, namely Tengger Desert, Taklimakan Desert, Badain Jaran Desert, Kubuqi Desert, Ulan Buh Desert, Kumtag Desert, Gul...
