However, if you have a few worksites within close proximity to each other, you might find that this is the ideal solution for you. You’ll be responsible for replacing a key player of the organization, getting them trained and certified, and on the road. If an employee leaves the company or is promoted, they take their skills and certification with them, leaving you without a drone pilot. Internal drone pilots must be Part 107 certified to fly a drone for commercial purposes. This will play a role in the affordability of having your own internal drone program.Ĭompanies also need to consider employee turnover and training expenses. Consider travel expenses such as meals, vehicle rental, fuel, and lodging costs. Within a few hours, you will have stockpile volume reports to share with your team.įlying your own drone can be more expensive if your company has worksites across multiple states or even hundreds of miles apart. You can invest in a drone, get certified, measure your stockpiles, and upload the imagery to Stockpile Reports. This solution is perfect for companies that have a couple of worksites within a short drive of each other. Many companies choose to complete their stockpile measurements with their own drones. It’s important for your company to evaluate whether you want to invest and maintain your own internal drone program or if it would be better to partner with a company that can complete the drone measurements for you. We created a solution for companies that is straight-forward and simple. Whether you fly yourself or have Stockpile Reports fly for you, we believe that completing inventory shouldn’t be a hassle. Drones allow you to measure all of your stockpiles in just a few minutes. For example, flatter stockpiles will benefit more from a high GSD than taller stockpiles.There is no doubt that using a drone for measuring stockpiles is a great solution for many companies with inventory spread across large worksites. Vertically, they lower the uncertainty in Z values, which is proportional to the resolution. Horizontally, high-resolution photogrammetric results create more precise stockpile models, and thus better volume measurement accuracy than ones interpolated from certain measured points. A photogrammetric survey with a fine ground sampling distance (GSD, which indicates the actual distance each pixel represents) is able to better describe irregular stockpiles in detail. When it comes to stockpile volume measurements, stockpiles do not conform to a perfect shape. Why use photogrammetry for stockpile volume measurements? High-resolution images give you more details of the mapped stockpiles These top mining companies claim that by applying the photogrammetry workflow with Pix4Dmapper, they can achieve measurement accuracies of around 2-5% for their stockpile volumes. Of the biggest 40 mining companies announced in PWC’s mining report, nearly half of them use Pix4Dmapper photogrammetry software for stockpile measurement and volume comparison as part of their mining workflow.Ĭalculating and managing stockpile inventory, that is, finding a solution for accurate volume measurement and easy inventory management, is one of the biggest challenges in the mining industry. Speed and accuracy: that's the reason why most of the largest mining companies use drones and photogrammetry software in their workflow.
