Fig. 1: Predicted canopy height map over China and regional comparisons across different land covers in 2019.
From: Substantial contribution of trees outside forests to above-ground carbon across China
The figure illustrates the predicted canopy height map of China at a 10 m resolution for the year 2019 using the GEDI-Sentinel based U-NET canopy height model. Plot a shows the nationwide spatial distribution of vegetation height. Plots b–g provide detailed comparisons between satellite imagery and predicted canopy height across different land cover types: b trees in the forests of Heilongjiang (Northeast), c trees in urban Shanghai (East), d trees on croplands in Sichuan (Southwest), e trees on plains in Inner Mongolia (North), f trees in mountainous areas in Chongqing (Southwest), and g trees in the forests of Hainan (South). These comparisons demonstrate the model’s robustness in capturing vegetation structure across various landscapes, including dense forests, croplands, plains, urban areas, and mountainous terrain.
