<b>Leveraging Chinese GaoFen-7 imagery for high-resolution building height estimation in multiple cities</b>

This is a building height dataset estimated from Chinese Gaofen-7 imagery. The estimated building heights in the different cities (Tianjin, Lanzhou, Chongqing, Ningbo, Guangzhou, and Shenzhen) are highly consistent with the reference building height data obtained from field-measured building height data, building floor data, and airborne light detection and ranging (LiDAR) data. The R² varies from 0.75 to 0.90, while the root mean square error (RMSE) ranges from 4.06 m to 8.06 m. The validation of the estimated building heights over 106,366 buildings using airborne LiDAR height data yielded R² and RMSE of 0.90 and 6.72 m for Shenzhen and 0.89 and 4.06 m for Hong Kong, respectively. Note that the Viewing angles for the GF-7Backward image are -5°, so there is a small offset between the building roof derived from GF-7 image and the building roof derived from other images.
