High precision stockpile volume calculation was required  to be accomplished in a short time, without using Ground Control Points in a safe and automated process. The area was surveyed with DJI Phantom 4 Pro with the use of DatuFly™ drone app. The received images were later on processed with DatuSurvey™ Enterprise. This case study describes the outputs received with  DatuSurvey™ Enterprise Softwar and compares them to the results achieved with the traditional surveying method. In the end, we describe the object elimination processing. Data was collected with a DJI Phantom 4 Pro drone using a 20 MP camera. Mission was planned with flight planner app DatuFly , allowing quick, precise and automatic image capturing. Flight duration was 6 minutes at an altitude of 132 ft. (40m). Resolution was 2.4cm/pixel.
