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.
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.
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.
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.
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 ...
At the core of a modern outage management system is a detailed network model of the distribution system. The utility's geographic information system (GIS) is usually the source of this network model. By combining the locations of outage calls from customers, a rules engine is used to predict the locations of outages.
