This paper discusses the issues of creating an aerial survey complex based on an unmanned aerial vehicle. The analysis of the efficiency of using aerial survey complexes based on unmanned aerial vehicles for operational monitoring of the state of natural and man-made territorial complexes is carried out. The paper considers the process of developing a modified control system for unmanned aerial vehicles, as well as the subsequent photogrammetric processing of aerial photographs. The quality of electronic units installed on unmanned aerial vehicles has been determined. The created modified control system for unmanned aerial vehicles and geographically referenced terrain orthophotomaps obtained by photogrammetric methods make it possible to classify the captured objects, perform their vectorization and provide each object with semantic information. The developed modified aerial survey complex will allow real-time monitoring of the state of natural and man-made territorial complexes based on remote sensing data from UAVs.
