Volume calculation can be done in a number of different ways, which includes traditional GPS measurements and surveying by drone. Some stockpiles however require a more accurate solution, depending on the value of the actual material. Terrestrial laserscanners offer a highly accurate solution and ultimately are better for accurately calculating total stockpile volume, its value and perhaps transportation costs as well.
Some materials can be quite valuable, which means highly accurate terrestrial laser scanners are the only way to accurate calculate the total stockpile value. And in some cases a terrestrial laser scanner is the only option available. For example, when working underground or in an area where drones are not allowed or simply introduce too much other risks.
This animation showcases some of the basic steps we go through while scanning and processing the data.
