Feature Description
Optical remote sensing imagery is often affected by atmospheric cloud layers during imaging processes. Thin clouds cause ground objects to appear blurry, while thick clouds completely obscure features. Cloud shadows may also project onto the ground surface. To enhance data quality, cloud-affected areas can be replaced with cloud-free imagery from other temporal phases.
The Cloud Removal function addresses these issues by automatically identifying cloud-covered areas and replacing them with cloud-free image data.
When using this function, ensure the original image and reference image share consistent pixel formats, number of bands, and coordinate systems.
