Title: Geophysical Mapping Versus Locating Utilities: Where Are We and Where Do We Go from Here?

Availability: Transportation Research Board Business Office 500 Fifth Street, NW Abstract: Geophysical tools have been used for locating underground utilities for decades. Modern pipe and cable locators are highly tuned EM devices used to map metallic utilities or utilities that have had a metallic tracer wire attached. These tools have limitations, as all tools do, and the continuing need to improve detection and to map not just locate buried utilities has led to implementations of technologies such as ground penetrating radar (GPR). GPR has been developed into a tool with worldwide use for locating and mapping utilities. Like EM locators, GPR has limitations. High conductivity soils such as clays and soils saturated with brackish or salty water limit the penetration depth of GPR signals. Many geophysicists and engineers involved in utility mapping have concluded that multi-sensor systems are the best way to accomplish mapping in all soils and conditions. This paper describes the current status and continued development of a system to gather and fuse data from multiple geophysical sensors for mapping utilities.
