Stockpile Measurement Services by Laser Survey

SPECTRO can measure and quantify dry bulk inventory stockpiles, such as coal and petroleum coke, using advanced laser surveying technology. Laser surveying provides faster stockpile measurement times, better accuracy, and real time results. This laser survey accurately determines the volume of an irregularly-faced stockpile, without the necessity of complete stockpile grooming. In fact, minimal stockpile grooming is ideal for best results.
Inspection reports include 3D images of the stockpile, and can be quickly produced.
Laser surveying experts measure bulk inventory stockpiles, including coal, minerals, petroleum-coke, agricultural products and dry bulk chemicals.
