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 ...
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.
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.
Subsurface Utilities are the utility networks generally laid under the ground surface. These utilities include pipeline networks for water supply, sewage disposal, petrochemical liquid transmission, petrochemical gas transmission or cable networks for power transmission, telecom data transmission, any other data or signal transmission.
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 ...
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.
Ground penetrating radar is a non-invasive technique, and is used within civil construction and engineering for a variety of uses, including detection of utilities (buried water, gas, sewerage, electrical and telecommunication cables), mapping of soft soils, overburden for geotechnical characterization, and other similar uses.

A cave survey is a map of all or part of a cave system, which may be produced to meet differing standards of accuracy depending on the cave conditions and equipment available underground. Cave surveying and cartography , i.e. the creation of an accurate, detailed map, is one of the most common technical activities undertaken within a cave and ...
