Enhancing Selkirk College's RPAS Capacity

光距离和测距，或称激光雷达，是一种活跃的遥感技术。激光雷达系统发射激光脉冲，并测量反射光被探测到的时间。然后，可以使用光速来计算与系统的距离。生成的数据表示为三维点云。激光雷达在林业中有许多应用，因为一些激光脉冲通过树冠到达地面，或者被森林树冠的部分反射回来。这使得只需一次调查就可以创建详细的地表或地形模型，以及森林本身的树木和灌木的详细模型。精确而紧凑的激光雷达系统可以在相对便宜的遥控航空系统(RPA-也称为无人机)上飞行，使组织能够根据需要收集自己的航空激光雷达。塞尔柯克学院要求购买绿谷国际LiAir S220及相关软件。LiAir 220可以与我们现有的DJI M600 Pro六角测量仪一起使用，以收集数据，以支持我们与小型RPA公司及其林业行业客户合作开展的应用研究项目。

Light Distance And Ranging, or lidar, is an active remote sensing technology. The lidar system emits laser pulses and measures the time until the reflected light is detected. Distance from the system can then be calculated using the speed of light. The resulting data is represented as a 3D point cloud. Lidar has many applications in forestry because some of the laser pulses reach through the canopy to the ground, or are reflected back by parts of the forest canopy. This enables the creation of both detailed surface or terrain models, and detailed models of trees and shrubs in the forest itself from a single survey. Accurate and compact lidar systems can be flown on relatively inexpensive remotely piloted aerial systems (RPAS - also known as drones), enabling organizations to collect their own aerial lidar as needed. Selkirk College is requesting a Green Valley International LiAir S220 and related software. The LiAir 220 can be used with our existing DJI M600 Pro hexacopter to collect data in support of applied research projects we are conducting in partnership with small RPAS companies and their clients in the forest industry.
