Subsurface Information Modeling (SIM): Using LiDAR Technologies to Build on SUE, SUM, and BIM Building on SUE, SUM, and BIM to Advance Underground Stewardship The use of Subsurface Utility Mapping (SUE) dates back to the early 1980s. In 1991, SUE gained an official endorsement from the Federal Highway Administration (FHWA). A few years later, the famous Purdue study proved its […]

Underground Infrastructure Mapping with Mobile Lidar and GPR

September 3, 2018 Leave a comment

Governments are beginning to mandate that underground infrastructure mapping be carried out as national policy. Underground infrastructure mapping of utilities and other infrastructure is one of the major challenges in creating a digital twin at the municipal, regional, and national level. LiDAR reality capture of the above-ground ground features simultaneously with ground penetrating radar (GPR) scans of subsurface infrastructure at […]
