Overall map accuracies at classification stages 1 and 2. (A) Stage-1 formation level map OA, including native and non-native vegetated and non-vegetated classes, for the seven alternative feature spaces F1–F7. (B) Stage-2 physiognomy level map OA for native vegetation classes only, across the seven alternative feature spaces F1–F7. For each feature space, the classification process has been repeated 500 times with different training/validation vegetation reference data splits. Aside from the paired groups indicated in black, all post-hoc pairwise comparisons between feature spaces (Tukey Multiple Comparison tests) where significant p ≤ 0.05.
