Optimizing KNN and multi-features extracted from GF-1 and GF-3 for forest above-ground biomass (AGB) estimation

China is advancing toward its carbon peak and neutrality goals, in which accurate above-ground biomass (AGB) estimation is crucial. In this study, GF-1, GF-3, and their combined data from Yiliang and Puer were used, testing KNN and two enhanced algorithms (KNN-FIFS and GA-KNN) for AGB estimation. We...
