Abstract
The article presents the use of unmanned aircraft systems in an aerial photographic survey of a gold ore deposit. The author's methodology for conducting surveys is described as stepwise. A comparative study of deposit ore zones topographic map created based on instrumental measurements was also carried out, using the aerial photography data-driven digital surface model. This study was conducted at the open pit of TOO GRK Tuz (A mining company in Kazakhstan) and includes the following stages: a topographic survey of the undeveloped area, survey scale 1:1000, a vertical interval of 1.0 m; modeling of geospatial data (point cloud, orthophoto map, digital surface model); comparison of existing topographic plan with digital surface model.
