The article discusses how remote sensing can be used to survey, monitor, and evaluate landslides. By studying specific points, researchers can determine the boundaries, movement characteristics, and scale of landslides. Direct monitoring using remote sensing is challenging due to the difficulty in predicting large-scale landslide movements accurately. Instead, indirect monitoring focuses on environmental changes caused by landslides. The study also highlights examples of remote sensing monitoring of lake changes, ecological damage, and new landslides triggered by landslide dam bursts. Evaluation of landslides involves assessing stability, predicting future activities, identifying influencing factors, and evaluating regional hazards. Examples from Tiantaixiang, Qianjiangpin, and the Three Gorge area are used to illustrate these concepts.
