A global 150-m dataset of urban building heights around 2020

Here, we provide a 150-m global urban building heights dataset around 2020 by combining the spaceborne lidar (Global Ecosystem Dynamics Investigation, GEDI), multi-sourced data (Landsat-8, Sentinel-2, and Sentinel-1), and topographic data. The validation results revealed that the GEDI-estimated building height samples were effective in comparison to the reference data (Pearson's r = 0.81, RMSE = 3.58 m). The mapping product also demonstrated good performance, as indicated by its strong correlation with the reference data (Pearson's r = 0.71, RMSE = 4.73 m).

The global dataset of our urban building heights is availably visible by following the website (https://nju-eco-lidar.projects.earthengine.app/view/gbh2020), powered by the Google Earth Engine (GEE).
