【摘要】 在陕西南部地区，抽水蓄能电站站址的资源相对较好，然而这些站点处于秦岭腹地，地形复杂，交通不便，气象条件差，且在前期勘测阶段测量区域较大，导致地形测绘工作实施困难，进度难以预测。文章结合实际案例，探讨了动力三角翼机载激光雷达（LiDAR）系统在这种特殊地形中的应用，相比无人机机载LiDAR技术，该系统在大面积大比例尺地形测绘中具有显著的应用优势。更多还原

【Abstract】 In the southern part of Shaanxi Province, the resources at pumped storage power station sites are relatively good, however, these stations are located in the hinterland of Qinling Mountains, with complex terrain, inconvenient transportation, poor meteorological conditions, and large measurement area in the early survey stage, which makes the implementation of topographic surveying and mapping di ffi cult and the progress di ffi cult to predict. Combined with practical cases, this paper discusses the application of powered delta wing airborne Light Detection and Ranging(LiDAR) system in this special terrain. Compared with UAV airborne LiDAR technology, this system has significant application advantages in large area and large measuring scale topographic survey and mapping.更多还原
