The aim of this course is to provide field-based demonstrations of Aerial Surveying using Unmanned Aerial Vehicle to acquire ultra-high resolution imagery of the study area, which will later (in the lab) be used to generate various geographic information products such as orthophoto, point clouds, digital elevation models (DEMs), digital surface models (DSMs) and detailed mapping from high spatial-resolution orthomosaic image. In particular, the detailed mapping of various land surface entities can be mapped accurately on the produced high resolution image.
Drone technology also known as Unmanned Aerial Vehicles (UAVs) is the future for cost-effective and rapid data acquisition. Furthermore, UAVs can be used in high-risk situations and inaccessible areas in real-time. UAVs have been found to be a low-cost, alternative digital photogrammetry as opposed to the Light detection and ranging (LiDAR) technique. This has revolutionized 3-D topographic surveys in most geological engineering and science works.
