Utilizing a combination of traditional survey, terrestrial LiDAR and unmanned aerial systems with high-definition imaging capabilities, LDG conducted a 3D volumetric survey encompassing the storage yard, plant and distribution centers for National Gypsum Corporation’s Shippingport, PA facility. The information captured during the field operations was processed with Esri SiteScan and Autodesk Civil3D to generate highly accurate point cloud dataset, calculate quantities, geographically locate individual piles and facilities, and publish tabulations, maps and reports required for annual audit processes.
