Characteristics of Surface Deformation in Lanzhou with Sentinel-1A TOPS [PDF]
Geosciences, 2020 While surface deformations and their impact on buildings have been observed in the city of Lanzhou, it is difficult to find studies of surface deformation and the influential factors in the recent decades. This study was designed to detect the spatial position of these surface deformations and to understand the mechanism behind them.
