swissSURFACE3D

swissSURFACE3D models all natural and man-made objects of the surface of Switzerland in the form of a classified point cloud. These high-accuracy and high spatial density data are collected by airborne LiDAR. swissSURFACE3D is produced in 1 km2 tiles. The tiles are numbered based on the coordinates in kilometers of their southwest angle.swissSURFACE3D数据集以分类点云的形式，对瑞士地表的全部自然与人工地物进行建模。此类数据兼具高精度与高空间密度特性，通过机载激光雷达（LiDAR）采集获取。swissSURFACE3D以1平方千米的分幅瓦片进行生产，各瓦片依据其西南角的千米级坐标进行编号。
