Small Unmanned Aerial Systems (sUAS or drones) along with exciting new image processing algorithms are enabling a fundamental change in how stockpile volumetric computations are performed. It is now possible to create accurate three dimensional models of stockpile areas using inexpensive cameras carried by a low cost sUAS (drone). From these 3D models, volumetric computations are easily derived. These new technologies result in significantly lower cost of collection, improved accuracy and non-disruptive data collection. Best of all, they keep data collectors out of harm’s way with collection performed from a low altitude drone.
