Abstract
Currently, the existing approaches to geodetic support for the design, survey, construction and reconstruction of buildings and structures do not fully meet the needs of the construction industry. Digital large scale topographic plans do not fully reflect the situation on the construction site. In this regard, to supplement digital engineering and topographic plans with information obtained using the survey materials of unmanned aircraft systems (UAS) is proposed. The article discusses the possibilities of obtaining and processing the materials of surveying with UAS at low altitudes, using the example of the construction of a new metro station in Novosibirsk. The DJI Phantom 4 PRO quadrocopter was used as a UAS. The accuracy of the obtained orthophotoplan is sufficiently suitable as explanatory information for the digital engineering and topographic plan of the object under study.
