The relevance of the topic is due to the increasing need of the mining industry for prompt and highly accurate spatial data acquisition for mining operations and safety. The article presents a methodology for creating a digital model of the earth's surface in the development of deposits using unmanned aerial vehicles (UAVs). Modern technologies of aerial photography, data processing and construction of high-precision digital models of the Earth's surface are considered. The stages of aerial photography and image processing are described, allowing minimizing errors and improving the accuracy of model construction. A technique is proposed to improve the accuracy of models by optimizing the flight parameters of UAVs and calibrating sensors. The results obtained can be applied to optimize mining operations and geodetic monitoring of the state of man-made facilities and environmental control.
