Stockpile Volume Measurement & Earthwork Estimation

Overview

Drone-based volumetric surveys enable precise calculation of stockpile and excavation volumes in construction, quarrying, and mining sites. Using high-resolution imagery and photogrammetry, drones produce accurate 3D surface models to estimate material quantities. This method replaces manual or ground-based volume surveys with safer, faster, and highly accurate alternatives.
