Scatterplots of measured AGB (t/ha) in wheat and the AGB estimated with three machine learning techniques (left: SMLR, second column: SVR, third column: ELM, right: RF) from the VIs alone (a–d), canopy height metrics alone (e–h) and the combined data (i–l). The data points displayed in each plot represent the validation set. The dashed diagonals represent 1:1 lines and the solid lines represent the fitted linear functions
