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.

Utility mapping and data distribution system and method

Locating and/or marking equipment, such as a locate transmitter or locate receiver, a marking device, or a combined locate and marking device, may be communicatively coupled to and/or equipped with a mobile/portable device (e.g., a mobile phone, personal digital assistant or other portable computing device) that provides processing, electronic storage, electronic display, user interface, communication facilities and/or other functionality (e.g., GPS-enabled functionality) for the equipment. 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 and/or marking operation (e.g., locate information, marking information, and/or landmark information). Such records may be formatted in various manners, processed and/or analyzed on the mobile/portable device, and/or transmitted to another device (e.g., a remote computer/server) for storage, processing and/or analysis. The mobile/portable device also may provide redundant, shared and/or backup functionality for the equipment to enhance robustness.

Locating equipment communicatively coupled to or equipped with a mobile/portable device

Generating a searchable electronic record of a locate operation performed by a locate technician. The locate operation comprises identifying, using at least one physical locate mark, a presence or an absence of at least one underground facility within a dig area, wherein at least a portion of the dig area may be excavated or disturbed during excavation activities. A bare grid is displayed on display device and, via a user input device associated with the display device, at least one 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 including the at least one digital representation of the at least one physical locate mark. Information relating to the marked-up grid is electronically transmitted and/or stored so as to generate the searchable electronic record of the locate operation.

Methods, apparatus and systems for generating searchable electronic records of underground facility locate and/or marking operations

A locate device for a locate operation to detect a presence or an 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. In various aspects, methods and apparatus relate to: selection of an appropriate “base” facilities map, or information from a database of facilities map data, relating to a given work site/dig area; selection of an appropriate pan and/or zoom (resolution) for displaying facilities map information; appropriately updating displayed facilities map information while a locate device is used during a locate operation (e.g. changing pan, zoom and/or orientation); overlaying on the displayed facilities map information locate information and/or landmark information relating to the locate operation; and storing locally on the locate device, and/or transmitting from the locate device, facilities map information and/or overlaid locate/landmark information (e.g., for further processing, analysis and/or subsequent display).

Methods and apparatus for overlaying electronic locate information on facilities map information and/or other image information displayed on a locate device

Methods and apparatus for generating a searchable electronic record of a locate operation in which a presence or an absence of at least one underground facility within a dig area may be identified using one or more physical locate marks. Source data representing one or more input images of a geographic area comprising the dig area is received and processed so as to display at least a portion of the input image(s) on a display device. One or more digital representations of the physical locate mark(s) applied to the dig area during the locate operation are added to the displayed input image(s) as “locate mark indicators” so as to generate a marked-up image. Information relating to the marked-up image is electronically transmitted and/or electronically stored so as to generate the searchable electronic record of the locate operation.

Searchable electronic records of underground facility locate marking operations

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.
