Abstract: This paper introduces the main components and operational processes of UAV remote sensing systems, and focuses on the application of UAV remote sensing in the land survey and measurement community, and takes the example of the land survey and measurement community at the Mazhu Expressway (Dawu to Hong'an Section) as an example. Topographic surveys of UAV aerial surveys were conducted and the accuracy of topographic maps was analyzed. The results show that the application of drone aerial survey in the land survey field is feasible, and the efficiency is relatively high, which can meet the requirements of large scale mapping accuracy.

Key words: UAV, land survey field, UASMaster
