This method was still time-consuming and lacked precision.ĭrones catapulted stockpile measurement tools to a new level of technological advancement. A drone only needs a few minutes to complete a job that would otherwise take hours using manual tools. The process for using a drone to measure stockpiles begins with flying the drone to capture aerial images. The drone can determine its own flight path-all that’s required is for the remote pilot to input a few variables about the area being flown like GPS data or ground control points (GCP method). Then stand by and let the drone collect the data.įrom there, all that’s left to do is upload the data into a software that can turn it into a 3-D model, like the Propeller Platform (this is one example of many drone mapping software options). Once the drone data is uploaded and processed, the software automatically calculates the volume and provides additional tools to calculate tonnage, cost, and other metrics about the stockpiles. You can specify a reference level and the type of material in most software settings. With cloud-based drone software, the calculations can be accessed in the field on an iPad for a quick turn-around time. Having accurate measurements can reduce overestimated material and supply orders, cutting back on waste and unnecessary spending. Additionally, more frequent data collection can keep inventory counts up-to-date.Ĭonstruction companies can collect stockpile measurements as often as they want to fly the drone. It becomes much easier to conduct frequent surveys with a drone, enabling monthly instead of quarterly or annual inventory counts. This can be extremely useful when dealing with erodable material that needs to be audited frequently. Measurements such as volume, density, and tonnage can be precisely calculated using drone mapping software. Drone data is incredibly accurate, with an accuracy of 1/10ft (3cm) for stockpile measurements. This level of accuracy is accomplished through a variety of drone surveying and mapping methods, such as GCPs, photogrammetry, and LiDAR. With the appropriate drone mapping software, construction companies have fast and reliable access to cut and fill calculations, historical volume comparisons, and more.
