Laser scanning and ground penetrating radar (GPR) can be used together to create a full 3D model of underground utilities and above ground structures. Coastway and Minerex are companies that provide these surveying services. They use laser scanning to create high definition 3D models of surfaces and GPR to map underground structures and utilities to depths of 1-9 meters. The combined data sets can be analyzed and delivered to clients in various 3D and 2D formats.
