Abstract
The development of InSAR technique and the tremendous amount of SAR data have made InSAR the fundamental tool in landslide monitoring.This paper begins with the data selection, the effects of different datasets and scenes in landslide monitoring by InSAR are introduced. We analyze the main limitations affecting the accuracy of landslide monitoring by InSAR, and demonstrate the corresponding solutions. Subsequently, the methods in retrieving landslide-induced 3D displacement using InSAR are then classified, and their advantages, disadvantages, and application scopes are also analyzed. Finally, the limitations in landslide monitoring with InSAR, the corresponding solutions, and future development trends are discussed.
