(-37.4%). b) Spain (from tile region 30SWH with low average height 6.0m). Our map with RMSE: 4.7m, bias: 0.5 m (7.7%) outperforms the UMD map with RMSE: 5.2m, bias: -3.3 m (-54.9%). c) Netherlands (from tile region 31UFT with average height 6.6m). Our map with RMSE: 6.4m, bias: 3.9 m (59.9%) yields higher error than the UMD map with RMSE: 5.9m, bias: -2.2 m (-37.5%). In both b) and c), the UMD map underestimates high vegetation and misses small structures in low vegetation areas. d) Gabon, Lopé National Park (from the tile region 32MQE with the highest average height of 36.2 m). Our map with RMSE: 8.9m, bias: -4.8 m (-13.3%) outperforms the UMD map with RMSE: 11.4m, bias: -7.9 m (-21.8%). e) US,
