该数据集是基于全站仪测量得到的超级样地16块子样地的角点、地基LiDAR基站设置点和每株林木树干基部点的大地坐标数据及其他辅助数据。\n
\n全站仪数据采集时间自2008年6月3日至2008年6月12日，分两组进行，各采用1台全站仪，型号分别为TOPCON602、 TOPCON7002。对超级样地内总计1468棵青海云杉进行了坐标测量，并对所有的子样地角点和地基LiDAR基站点上设置的标桩的顶点进行了定位。这些定位结果是该数据集的主要数据内容。另外，2008-06-03，2008-6-4，2008-6-11用差分GPS Z-MAX对所有的标桩顶点进行了定位，通过手工测量每个标桩的高度，计算得到了标桩下地表的高度，最终生成了每棵树的地表三维坐标位置和超级样地地形图。这些数据组成该数据集的辅助数据。\n
\n本数据集可为建立真实三维林分场景，为各种三维森林遥感模型的发展与校正提供翔实的地面观测数据，同时为机载激光雷达森林参数提取提供地面验证数据。

The data set is based on the geodetic coordinate data and other auxiliary data of the corner points of 16 sub plots of super sample plots, the setting points of foundation lidar base stations and the base points of each tree trunk measured by the total station.\n
\nThe data acquisition time of total station is from June 3, 2008 to June 12, 2008. It is divided into two groups. One total station is used for each group, and the models are topcon602 and topcon7002 respectively. The coordinates of 1468 Qinghai spruce trees in the super sample plot were measured, and the vertices of all sub sample plot corners and stake set on the foundation lidar base station were located. These positioning results are the main data content of the data set. In addition, on June 3, 2008, June 4, 2008, June 11, 2008, all stake vertices were located with differential GPS z-max. by manually measuring the height of each stake, the height of the surface under the stake was calculated, and finally the three-dimensional coordinate position of the surface of each tree and the topographic map of the super sample plot were generated. These data form the auxiliary data of the data set.\n
