    en.wikipedia.org/wiki/Ground-penetrating_radar

    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 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 ...

  5. Detectable tape - Wikipedia

    en.wikipedia.org/wiki/Detectable_tape

    Detectable tape or Underground warning tape is a conductive tape typically applied over buried utilities made of non-conductive materials such as plastic, fiberglass, or cement. It is used because most utility location methods work best on conductive objects, and hence may easily miss structures made of non-conductive materials.

    en.wikipedia.org/wiki/Cave_survey

    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 ...
