Unmanned aerial vehicles (UAVs) have been used across a variety of different fields in civil engineering, such as geomatics engineering, transportation engineering, water resources engineering, and structural engineering. Through the basic techniques of photogrammetry and remote sensing and the utilization of different types of sensors mounted on these vehicles, UAVs are proving to be a versatile and economical option for data acquisition.

Examples of the applications of UAVs include topographic and cadastral mapping, as well as irrigation mapping and monitoring, structural health monitoring, traffic monitoring, infrastructure mapping and monitoring, and construction site inspections. They are proving to be an important technological asset for civil engineering. With advancements in sensor technology, as well as developments in data processing techniques such as artificial intelligence, computer vision, and pattern recognition, research into the application of UAVs in civil engineering is advancing at an ever-increasing pace.
