2020 年左右全球 150 米城市建筑高度数据集

在这里，我们通过结合星载激光雷达（全球生态系统动力学调查，GEDI）、多源数据（Landsat-8、Sentinel-2 和 Sentinel-1）和地形数据，提供了 2020 年左右 150 m 的全球城市建筑高度数据集。验证结果表明，与参考数据（Pearson's r = 0.81，RMSE = 3.58 m）相比，GEDI估计的建筑高度样本是有效的。测绘产品也表现出良好的性能，如其与参考数据的强相关性（Pearson's r = 0.71，RMSE = 4.73 m）所示。通过关注由 Google 地球引擎 （GEE） 提供支持的网站 （https://nju-eco-lidar.projects.earthengine.app/view/gbh2020），可以看到我们城市建筑高度的全球数据集。<br><br>

Here, we present a global urban building height dataset at ~150 m around 2020 by integrating space-borne lidar (Global Ecosystem Dynamics Investigation, GEDI), multi-source data (Landsat-8, Sentinel-2 and Sentinel-1) and topographic data. Validation results demonstrate that the GEDI-estimated building height samples are valid compared with the reference data (Pearson's r = 0.81, RMSE = 3.58 m). The mapping product also exhibits excellent performance, as evidenced by its strong correlation with the reference data (Pearson's r = 0.71, RMSE = 4.73 m).
