Embodiment 1
[0051] A method for accurately identifying new landslide areas based on multi-source time-series remote sensing images. The specific implementation steps of the method are as follows, as follows: figure 1 Shown:
[0052] Obtain multi-source remote sensing images before and after the landslide, and cut the digital terrain DEM, vegetation coverage index NVDI and surface radiation temperature remote sensing images before and after the landslide according to the preset landslide area to obtain the landslide area correspondence Remote sensing images of digital terrain DEM, vegetation cover index NVDI and surface radiation temperature before and after the landslide.
[0053] Specifically, in the solution provided in the embodiment of this application, the remote sensing images before and after the landslide include but are not limited to various remote sensing images such as orthophoto, fusion or mosaic. The remote sensing images before and after the landslide can be files in *.tif...
