Long range LiDAR scanning has significant potential for research in a wide area of geotechnical engineering, geological engineering and geoscience disciplines. This proposal is for the acquisition of a state-of-the-art long range scanner capable of imaging materials at distances of between 5m and 4km. The scanner will be used to characterize rock slopes for geotechnical and geoscience purposes and to allow accurate monitoring of slope deformations. It will provide valuable research opportunities of both an applied and pure nature. A major area of application of the long range LiDAR will be in the development and exploitation of Canada's natural resources. The scanner will allow improved understanding of slope instability, deformation and erosion in both open pit mine and harvested forest slopes. The scanner will be used to further our understanding of groundwater flow in fractured rock masses an important factor in groundwater resources characterization and in slope failure mechanisms. The use of the long range scanner in the characterization of the stratigraphy and geological structure in rock outcrops will also have important applications towards the hydrocarbons industry. Scanning will also be undertaken of pillars and mine walls in large underground excavations. An important area of focus will be the use of the long-range LIDAR to improve geohazard risk assessment of natural and engineered rock and soil slopes in addition to the monitoring of deformation and characterization of volcanic and glaciated slopes. Research will be conducted to improve the integration of the long range LiDAR imagery with multiple data sets available at the co-applicants institutions. These will include digital photogrammetry, satellite and ground -based InSAR and thermal imagery. The co-applicants will also strive to develop improve methods of data visualization and interpretation using augmented and virtual reality platforms available at SFU and UBC. The integration of the remote sensing datasets into state-of-the-art geomechanical and geoscience software will provide exciting new research opportunities. The long range LiDAR will provide excellent opportunities for state-of-the-art training to a large cohort of engineering and geoscience HQP.

长距离激光雷达扫描在岩土工程、地质工程和地球科学学科的广泛领域具有巨大的研究潜力。这项提议是为了购置一台能够在5米至4公里距离对材料成像的最先进的远程扫描仪。该扫描仪将用于岩土工程和地球科学目的的岩石边坡特性，并允许精确监测边坡变形。它将提供应用和纯自然的宝贵研究机会。 长距离激光雷达的一个主要应用领域将是加拿大自然资源的开发和利用。该扫描仪将有助于更好地了解露天矿和采伐森林边坡的边坡不稳定性、变形和侵蚀。该扫描仪将用于进一步了解裂隙岩体中的地下水流动，这是地下水资源特征描述和边坡破坏机制的重要因素。在岩石露头中的地层学和地质结构的表征中使用远程扫描仪也将对碳氢化合物工业具有重要的应用。还将对大型地下挖掘中的支柱和矿壁进行扫描。一个重要的重点领域将是使用远程激光雷达改进对自然和工程岩石和土壤斜坡的地质灾害风险评估，以及监测火山和冰川斜坡的变形和特征。将进行研究，以改进远程激光雷达图像与共同申请机构提供的多个数据集的整合。这些将包括数字摄影测量、卫星和地面干涉合成孔径雷达和热成像。共同申请人还将努力利用SFU和UBC提供的增强和虚拟现实平台开发改进的数据可视化和解释方法。将遥感数据集纳入最先进的地质力学和地球科学软件将提供令人兴奋的新研究机会。 远程激光雷达将为大批工程和地球科学HQP提供最先进的培训机会。
