Multidimensional Quantification of Engineering Distresses and Secondary Periglacial Hazards Along Linear Infrastructure in the Permafrost Region of Northeast China Using UAV-LiDAR and Synchronous Visible-Light Imagery

Permafrost degradation is intensifying differential settlement, structural deformation, and secondary periglacial hazards along linear infrastructure in cold regions, underscoring the need for monitoring approaches that integrate corridor-scale screening with fine-scale quantification. This study investigated highways,...

A Multi-Source Remote Sensing and Multi-Evidence Fusion Framework for Regional Permafrost-Condition Screening for Preliminary Engineering Planning in the Daxing’anling Region

Permafrost maps are important for regional planning in cold regions, but binary products do not represent gradients in thermal conditions, seasonal thaw response, or mapping confidence. This study developed an uncertainty-aware regional permafrost-condition screening framework for the Daxing’anling region during 2003–2...
