High-Resolution Spatial Modeling of Permafrost Landform: Polygonal Patterned Ground in the Three-River Source Region
Polygonal patterned ground (PPG) is an important remote-sensing indicator of permafrost dynamics, yet its high-resolution distribution in alpine permafrost regions remains unknown. In this study, we developed an ensemble modeling framework to map PPG in the Three-River Source Region (TRSR), northeastern Qinghai–Tibet P...
