WebJun 5, 2024 · Topographic correction requires elevation data for illumination correction over the shadowed regions of the satellite images. DEM should be of similar spatial resolution as that of satellite image. Further, slope angle (in degrees) and aspect angle are calculated from DEM using Horn’s method. WebWho We Are.
