  2. Ground-penetrating radar - Wikipedia

    en.wikipedia.org/wiki/Ground-penetrating_radar

    Ground-penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. It is a non-intrusive method of surveying the sub-surface to investigate underground utilities such as concrete, asphalt, metals, pipes, cables or masonry. [ 1 ]

  3. Geophysical survey (archaeology) - Wikipedia

    en.wikipedia.org/wiki/Geophysical_survey...

    Most commonly applied to archaeology are magnetometers, electrical resistance meters, ground-penetrating radar (GPR) and electromagnetic (EM) conductivity meters. These methods can resolve many types of archaeological features, are capable of high sample density surveys of very large areas, and of operating under a wide range of conditions.

  4. Lidar - Wikipedia

    en.wikipedia.org/wiki/Lidar

    Lidar (/ ˈ l aɪ d ɑːr /, also LIDAR, an acronym of "light detection and ranging" [1] or "laser imaging, detection, and ranging" [2]) is a method for determining ranges by targeting an object or a surface with a laser and measuring the time for the reflected light to return to the receiver.

    Electromagnetic methods, such as magnetotellurics, ground penetrating radar and transient/time-domain electromagnetics, surface nuclear magnetic resonance (also known as magnetic resonance sounding). [3] Borehole geophysics, also called well logging. Remote sensing techniques, including hyperspectral.

  6. Survey (archaeology) - Wikipedia

    en.wikipedia.org/wiki/Survey_(archaeology)

    Ground penetrating radar is a tool used in archaeological field surveys. In archaeology, survey or field survey is a type of field research by which archaeologists (often landscape archaeologists) search for archaeological sites and collect information about the location, distribution and organization of past human cultures across a large area (e.g. typically in excess of one hectare, and ...

  7. Exploration geophysics - Wikipedia

    en.wikipedia.org/wiki/Exploration_geophysics

    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. [5]

  8. Near-surface geophysics - Wikipedia

    en.wikipedia.org/wiki/Near-surface_geophysics

    Ground-penetrating radar is one of the most popularly used near-surface geophysics in forensic archaeology, forensic geophysics, geotechnical investigation, treasure hunting, and hydrogeology, with typical penetration depths down to 10 m (33 ft) below ground level, depending upon local soil and rock conditions, although this depends upon the ...
