Aiming to evaluate its effectiveness in multi-class land cover classification, the GF-6 WFV imagery was used to conduct large-scale land cover classification research in the complex mountainous region of southwest Sichuan. By combining spectral bands and calculating vegetation indices, the ability to monitor vegetation health was enhanced. The introduction of the red-edge band (B5) and yellow band (B8) provided new technical advantages for vegetation and land use classification. In terms of supervised classification methods, four approaches were employed, including Mahalanobis distance, Maximum likelihood, Convolutional neural networks (CNN), and Support vector machine (SVM).
