Abstract Two methods for removing the thin cloud cover from the RapidEye remote sensing imagery in western mountain areas of China based on Photoshop environment are introduced in this paper. One is to directly adjust the three bands respectively by adjustment function of levels, and the other is band substitution. In the second method, the first step is to substitute infrared band for blue band, and then three bands are adjusted respectively in levels. Test results show that the imagery quality is enhanced obviously when the processed imagery is compared with the original one, and the efficiency in the production practice is improved.
