Volumetric analysis can be performed on stockpiles using 3D laser scanning. For large stockpiles of materials, it can be extremely difficult to determine the volume of the material. Using laser scanners to capture the point cloud data of the stockpile, the volume can be determined regardless of size or shape.

Ground Penetrating Radar Surveying (GPRS)
Ground Penetrating Radar Surveying (GPRS) is a non-invasive way to detect surface and subsurface elements. This versatile method uses electromagnetic pulses to identify void spaces,
