This paper introduces application of unmanned aerial vehicle (UAV) in topographic survey of Yangtze River. Traditional measurement methods are insufficient and inaccurate due to the limitations of natural conditions in field, and sometimes danger to on-site surveyors. By applying aerial mapping system and GPS differential technology for UAVs in waterway, the working hours and labour intensity of this task was significant reduced, the safety of the surveying personnel and the measurement accuracy were highly improved. A real case was also carried out in 2021 in relation to the maintenance project of constructions in the middle and lower reaches of the Yangtze River Waterway.
