High-resolution (HR) optical remote sensing images are typically small in swath and, due to cloud cover, their revisit period, mosaic error, and other problems, it is often infeasible to obtain a large range of remote sensing images for a study area. Meanwhile, low-resolution (LR) satellite images suffer from insufficient spatial and texture information for ground objects. Therefore, classifying a study area with high spatial resolution, large area, and no cloud occlusion using optical remote sensing imagery is very difficult. In recent years, the rapid development of super-resolution reconstruction (SRR) technology has made high-quality spatial resolution reconstruction possible. The SRR of real images is usually accompanied by problems such as sensor spectral range differences, cloud occlusion in the research area, and the SRR algorithm sacrificing a lot of the original information. In this study, with an improved PGGAN, we use only a small number of samples, the wide-swath medium-resolution satellite was restored to the same resolution as the high-resolution satellite, a new method for SRR multi-spectral optical remote sensing image classification based on texture reconstruction information is proposed, and a wide range of high-precision feature classifications are achieved in the study area. In order to solve the problem of spectral distortion in the process of multi-spectral image SRR and the weak generalization of optical remote sensing image ground object classificatio...
