Variation of water bodies along highways in the Qinghai–Tibet Plateau over the past 20 years: A case study of G109 and G219
The water bodies existing along highways in the high altitude areas of the Qinghai–Tibet Plateau (QTP) will aggravate subgrade settlement and road damage, and affect the long-term stability of road networks. Based on remote sensing and geographic information system (GIS) techniques, this study analy...
