High Mountain Asia Multitemporal Landslide Inventories, Version 1

The mountains of Nepal are one of the most hazardous environments in the world, with frequent landslides caused by tectonic activity, extreme rainfall and infrastructure development. As a landlocked country, Nepal relies on proper functioning of major transportation networks such as the highways to sustain and improve the livelihoods of the population. Every year there are reports of landslides blocking the highways, especially during the rainy season; however, the frequency and location of landslides along the highway corridors are not well reported. RapidEye satellite imagery was used to create annual landslide initiation point inventories along three important highways in Nepal: the Arniko, Karnali, and Pasang Lhamu highway.

尼泊尔境内的山地是全球最具危险性的环境之一，区内滑坡灾害频发，诱因涵盖构造活动、极端降雨与基础设施建设。作为内陆国家，尼泊尔依赖高速公路等主要交通网络的正常运转，以维系并改善民众的生计。每年均有滑坡阻断高速公路的相关报道，尤其在雨季；但公路沿线滑坡的发生频次与分布位置却鲜有详实记录。本数据集借助RapidEye卫星影像，针对尼泊尔境内三条重要高速公路——阿尔尼科（Arniko）公路、卡尔纳利（Karnali）公路与帕桑拉穆（Pasang Lhamu）公路——构建了年度滑坡起始点清单。
