Relief digital surface model (LiDAR 2018)

The plane "Relief digital surface model (LiDAR 2018)" is the shaded image of the earth's surface with buildings and vegetation.<br> The data are based on airborne laser measurements with an average point density of 16 points per m2 and an altitude accuracy of 10 cm (1 sigma=68%). The aerial flight took place in the spring of 2018.本数据集“地表数字表面模型（Relief digital surface model，LiDAR 2018）”为包含建筑物与植被的地表晕渲影像。 该数据基于机载激光雷达（LiDAR）测量，平均点密度为16点/平方米，高程精度达10厘米（1σ=68%）。航空数据采集工作于2018年春季开展。
