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.名为"地形数字地表模型（LiDAR 2018）"的数据集为叠加建筑物与植被信息的地表晕渲图像。<br>该数据集基于机载激光雷达测量技术构建，平均点密度为每平方米16个点，高程精度达10厘米（1σ=68%），航空数据采集作业于2018年春季完成。
