The use of UAV is a revolution in accuracy of stockpile measurements.
Publications and our experience indicate the advantage of drones. Using a dense cloud of points, which is generated quickly and, what is very important, safely, we can achieve the error of not more than 0.5-3%. The use of UAV does not require the work suspension in the mine and it eliminates the necessity of direct access to dangerous zones. It enables measurements in totally inaccessible areas.
A dense DTM also depicts big land deformations connected with the effects of underground mining operations.
