Subsurface utility engineering (SUE) refers to a branch of engineering that involves managing certain risks associated with utility mapping at appropriate quality levels, utility coordination, utility relocation design and coordination, utility condition assessment, communication of utility data to concerned parties, utility relocation cost estimates, implementation of utility accommodation ...
Utility locating is the process of identifying and labeling public utility mains that are underground. These mains may include lines for telecommunication , electricity distribution , natural gas , cable television , fiber optics , traffic lights , street lights , storm drains , water mains , and wastewater pipes.
Different cable locators employ different methods to function. The two known methods, Passive Utility Detection locating naturally present or naturally produced signals known as a passive signal. The other is to locate a signal that is applied AKA an Active signal , [7] are called the Passive Utility Detection and Active Utility Detection.
Borehole radars utilizing GPR are used to map the structures from a borehole in underground mining applications. Modern directional borehole radar systems are able to produce three-dimensional images from measurements in a single borehole. [8] One of the other main applications for ground-penetrating radars is for locating underground utilities.
A 2-dimensional or 3-dimensional velocity map, showing the spatial velocity difference of the subsurface, can thus be created for observing the geological structures. Subsurface mapping by ambient noise tomography can be applied in different fields, such as detecting the underground void space, [ 4 ] monitoring landslides , [ 5 ] and mapping ...

An underground power line provides electrical power with underground cables. Compared to overhead power lines, underground lines have lower risk of starting a wildfire and reduce the risk of the electrical supply being interrupted by outages during high winds, thunderstorms or heavy snow or ice storms. An added benefit of undergrounding is the ...
Detection and analysis of the geophysical signals forms the core of Geophysical signal processing. The magnetic and gravitational fields emanating from the Earth's interior hold essential information concerning seismic activities and the internal structure. Hence, detection and analysis of the electric and Magnetic fields is very crucial.
