无人机测绘技术在航道养护中的应用OA

To address the challenges in waterway maintenance,such as complex terrain,extended mileage,and weak satellite positioning signals,this paper proposes the application of UAV surveying and mapping technology in the topographic survey for waterway maintenance.An analysis was made on the principles and advantages of UAV map-ping technology.Taking the waterway maintenance of Lijiang River in Guilin as an example,this paper explores the actual application method of UAV surveying and mapping technology in waterway maintenance.The results demon-strate that UAV mapping technology is able to significantly improve the efficiency and accuracy of waterway mainte-nance,reduces the demand for human and material resources,and exhibits broad application prospects.
