<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.
