Abstract: This paper proposes DGACO-Net, a new model combining deep belief network (DBN), graph convolution network (GCN), and ant colony optimisation (ACO) to address the challenges of feature extraction and spatial relationship modelling in multi-source remote sensing data for land cover classification. DBN is used to extract advanced features, GCN captures spatial topological relationships, and ACO optimises hyperparameters to enhance model accuracy. Experimental results on the UC Merced Land Use and WHU-RS19 datasets demonstrate significant improvements in classification performance, with accuracies of 95% and 94%, respectively, outperforming benchmark models like SVM, random forest, and CNN. Ablation studies and feature visualisation validate the synergy of DBN, GCN, and ACO. DGACO-Net shows great potential for remote sensing image analysis and land resource management, offering an innovative solution for multi-source data classification.
