该数据集是基于地基激光雷达（LiDAR）获取的超级样地林分3D结构的扫描点云数据及其它附属数据。数据获取时间自2008年6月4日至2008年6月12日。采用Riegl LMS-Z360i地基LiDAR。将超级样地划分为16块25m×25m的子样地，在每块子样地内设置LiDAR基站点，在每个基站点设置LiDAR采集3D全覆盖LiDAR点元数据。\n
\n该数据集的内容：每个LiDAR数据采集基站点的全站仪测量坐标（x, y, z），每个站点采集数据时用数显坡度计和角度仪测量的仪器姿态，以及每个站点的激光雷达扫描点云数据。本数据集可为建立真实的三维森林场景，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，同时为机载和星载遥感数据提供地面验证数据。
