The course "Complete knowledge of LiDAR surveys" provides a comprehensive introduction to LiDAR technology and its applications in UAV surveys. Participants learn about the principles and uses of LiDAR, compare it with photogrammetry, explore recommended UAVs and payloads, and examine real-world applications in inspection, construction, public safety, mining, cultural heritage, environment, and urban planning. The course includes case studies of road tunnel inspection and Conisbrough Viaduct. Through a summary module, an end-of-course exam, and guidance for next steps, participants gain a solid foundation in UAV LiDAR surveys and its practical implementation.
