“一带一路”中西亚及中国西北地区典型区域洪水遥感影像及解译数据集

中西亚及中国西北地区作为“一带一路”建设的重要组成部分，正面临洪水灾害对区域可持续发展的严峻挑战。鉴于该地区现有洪水灾害信息单一、分析提取不足等问题，本研究以2017–2022年“一带一路”中西亚及中国西北地区典型洪水的雷达影像为基础，通过面向对象法提取灾害前后的水体信息，采用变化监...The Belt and Road Initiative (BRI) is not only a large-scale cooperation framework connecting the world, but also shapes the global development landscape across economic, political, cultural and other fields, exerting a profound impact on the global development pattern. Floods and other geological disasters have severely impacted regional development. In view of the problems existing in this region such as single flood disaster information and insufficient analysis and extraction, this study takes radar images of typical regions in Central and West Asia and Northwest China under the Belt and Road Initiative from 2017 to 2022 as the basis, and adopts an oriented...
