Abstract

The AW3D30 dataset is a publically available, high-accuracy digital surface model; the model’s cited nominal elevation accuracy is 5 m (1σ). In order to verify the accuracy of AW3D30, we selected China as test area, and used field measurement points in the national control point image database as control data. The elevation accuracy of the field measurement points in the national control point image database is better than 1 m. The results show that the accuracy of the AW3D30 satisfies the requirement of 5 m nominal accuracy, and elevation accuracy reached 2 m (1σ). Accuracy is related to both terrain and slope. Accuracy is better in flat areas than in areas of complex terrain, and the eastern region of China is characterized by better accuracy than the western region.
