Geologic Applications of Mobile and Tripod LiDAR Systems

光探测和测距（LiDAR）系统是一种复杂的测量工具，它通过脉冲激光束扫描表面来创建高分辨率的地形数据。地面激光雷达系统，如安装在三脚架上的激光雷达系统，已经成功地用于监测露天采矿作业和评估山体滑坡的安全隐患。最近，移动激光雷达扫描系统也有了新的发展。在这里，可以在汽车、全地形车或步行穿越地形时收集高精度的地形数据。这些技术直到最近才被发明出来，并且这些技术在地质现场调查中的应用仍处于起步阶段。与Teledyne Optech合作，我们寻求将两种新仪器（北极星远程三脚架激光雷达和Maverick移动测绘激光雷达）应用于现场调查，这将为地质过程的解释创造创新的新产品。我们提出的项目特别旨在描述寒冷气候地质过程，这些过程决定了加拿大高北极地区地形的形态。Teledyne Optech公司的具体问题是，他们缺乏实地研究，证明这些新扫描仪在科学地质研究中的实用性。我们将通过提供有关地球科学家如何使用这些系统的信息来解决这个问题，帮助他们改进技术并开辟潜在的新市场。

Light Detection and Ranging (LiDAR) systems are sophisticated surveying tools that work by scanning asurface with a pulsed laser beam to create high-resolution topography data. Ground-based LiDAR systems,such as those mounted on tripods, have been used with great success for monitoring open-pit mining operationsand for assessing safety hazards from landslides. There have been recent developments in mobile LiDARscanning systems as well. Here, high-precision topographic data can be collected while traversing terrain in acar, by ATV, or on foot. These techniques have only recently been invented, and the application of thistechnology to geologic field investigations remains in its infancy. Working with Teledyne Optech, we seek toapply two new instruments (the Polaris long-range tripod LiDAR, and the Maverick mobile mapping LiDAR)to field investigations that will create innovative and novel products for the interpretation of geologicprocesses. Our proposed project specifically aims to characterize cold-climate geologic processes that dictatethe morphology of the terrain in the Canadian High-Arctic. Teledyne Optech's company specific problem isthat they lack field studies that demonstrate the utility of these new scanners for scientific geologic research.We will address this problem by providing information about how geoscientists might use these systems,helping them to make technology improvements and open up potential new markets.
