TLDR
The method and device for locating underground utilities within an area includes traversing the area with a plurality of underground utility sensors and obtaining area location data to locate the area traversed as mentioned in this paper.Abstract:
The method and device for locating underground utilities within an area includes traversing the area with a plurality of underground utility sensors and obtaining area location data to locate the area traversed. The sensor data and area location data are used to map the location of one or more utilities within the area traversed.read more

Utility mapping and data distribution system and method
Gary Young,Kevin L. Alft +1 more
TL;DR: In this article, a system and method of mapping underground utilities and other subsurface objects involves one or more of acquiring utility location data using a number of different detectors and sensors, processing the multiple detector/sensor output data to produce mapping data, storing the mapping data in a database, and providing access to and use of the stored mapping data by subscribing users on a usage fee basis.
Patent
Locating equipment communicatively coupled to or equipped with a mobile/portable device
TL;DR: A mobile/portable device may be mechanically and/or electronically coupled to the equipment, and may be programmed so as to log and generate electronic records of various information germane to a locate/mark operation as discussed by the authors.
Patent
Methods, apparatus and systems for generating searchable electronic records of underground facility locate and/or marking operations
TL;DR: In this paper, a digital representation of the at least one physical locate mark is added to the displayed bare grid so as to generate a marked-up grid, which is then transmitted and/or stored to generate the searchable electronic record of the locate operation.
Patent
Methods and apparatus for overlaying electronic locate information on facilities map information and/or other image information displayed on a locate device
TL;DR: In this paper, a locate device for a locate operation to detect a presence or absence of one or more underground facilities is configured to access and display facilities map information, and/or other image information, as a visual aid to facilitate the locate operation.
Patent
Searchable electronic records of underground facility locate marking operations
TL;DR: In this article, the authors present a searchable electronic record of a locate operation in which a presence or absence of at least one underground facility within a dig area may be identified using one or more physical locate marks.

TL;DR: In this article, a multisensor vehicle-mounted mine detector has been used for detecting objects in the ground while moving, where a navigational system tracks the coordinates of the detected objects, performs data fusion, declares whether the object is a target worthy of interest and if so, stops the vehicle with a trailing thermal neutron activator sensor (TNA) over the coordinates and interrogates the object with slow neutrons to confirm whether it contains sufficient nitrogen to indeed be a mine.
Patent
System for locating multiple concealed underground objects
Alan J. Rider,Lester R. Querry +1 more
TL;DR: In this paper, an improved locator system was proposed which simultaneously couples a number of different frequency signals to the underground conductive lines, for the purpose of locating and distinguishing between the underground lines.
Patent
Method and apparatus for determining direction to and position of an underground conductor
TL;DR: In this article, a unique antenna unit having upper and lower sensors, each sensor having two orthogonal solenoid coils, are processed to yield corresponding digital values, which are combined in a novel formula to yield a value which has been empirically found to be indicative of lateral postion.
