Landslides arc the most common type of geological disaster. Research on the formation mechanism and influencing factors of landslide events will shed light on the identification of the hidden dangers of potential landslides that may be in similar environments for further monitoring and early warning. High-precision deformation monitoring of the post-landslide area is also helpful during the emergency rescue period in case of potential secondary dangers. In this paper, application of multi-platforms RS are introduced, including multitemporal satellite images, InSAR method and unmanned aerial vehicle photogrammetry for the pre- and mid-disaster phases, while the ground-based radar for the postdisaster deformation observation. Different features of each method for the landslide study are compared in generally. And an universal technical workflow is concluded. Our research provides significant guidelines for investigating potential landslide dangers and for landslide disaster emergency response and assessment. be utilized to observe the postdisaster deformation of the landslide.
