Abstract: 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.

Abstract: Methods and apparatus for facilitating detection of a presence or an absence of at least one underground facility within a dig area. Source data representing one or more input images of a geographic area including the dig area is electronically received at a first user location, which may be remote from the dig area. The source data is processed so as to display at least a portion of the input image(s) on a display device at the first user location. One or more indicators are added to the displayed input image(s), via a user input device associated with the display device, to provide at least one indication of the dig area and thereby generate a marked-up digital image. In one example, the indicator(s) is/are added to the displayed input image(s) without acquiring geographic coordinates corresponding to the indicator(s).

Abstract: Methods and apparatus for generating electronic records of marking operations for underground facilities/utilities. Electronic records of marking information may be logged/stored in local memory of a marking device, formatted in various manners, processed and/or analyzed at the marking device itself, and/or transmitted to another device (e.g., a remote computer/server) for storage, processing and/or analysis. In one example, multiple pieces of geo-location data (e.g., from a GPS receiver) are collected and logged per actuation of a marking device (e.g., a trigger-pull to dispense marking material). A computer-generated image or other visual representation of the marking operation may be electronically rendered in a display field based on logged marking information, essentially in real time as the marking operation is conducted, and/or recreated thereafter based on one or more stored electronic records.

Abstract: Methods and apparatus for facilitating detection of a presence or an absence of at least one underground facility within a dig area. A digital image of a geographic area including the dig area is electronically received, and at least a portion of the received digital image is displayed on a display device. The dig area is delimited on the displayed digital image, via a user input device associated with the display device, so as to generate a marked-up digital image including a delimited dig area, without acquiring geographic coordinates to delimit the dig area. Information relating to the dig area is electronically transmitted and/or electronically stored so as to facilitate the detection of the presence or the absence of the at least one underground facility within the dig area.

Abstract: Methods and apparatus for assessing a locate and marking operation. Ticket information is received as provided to a first locate technician prior to performing the operation. A locate manifest is received including a digital marked-up image of a geographic area surrounding a dig area in which the operation was performed, on which image at least one digital representation of at least one locate mark is electronically overlaid. The locate manifest, at least some of the ticket information, and a plurality of icons representing different possible quality assessments of the locate and marking operation are displayed. The plurality of icons includes an approved icon representing a satisfactory locate and marking operation, a QC icon representing an unsatisfactory locate and marking operation, and a coach icon representing that the first locate technician requires coaching. One of the displayed icons is selected so as to provide a quality assessment of the locate and marking operation.

Abstract: Locate information, marking information, and/or landmark information relating to a locate operation and/or a marking operation to detect and/or mark a presence or an absence of at least one underground facility is categorized into a plurality of display layers for electronic rendering. At least some of the display layers may be independently enabled or disabled for display such that only enabled display layers are displayed in a display field of a display device. Alternate enabling and disabling of one or more display layers facilitates comparative viewing of the layers. A layer directory or layer legend pane may be displayed to allow for selective enabling/disabling of one or more layers. One or more layers further may be categorized into sub-layers, and respective sub-layers of a given layer similarly may be independently enabled or disabled for display.

Abstract: Methods and apparatus for providing on a display device an electronic rendering of a locate operation to detect a presence or an absence of an underground facility. One or more electronic detection marks are displayed in a display field of the display device, based at least in part on locate information generated by a locate device used for the locate operation. The locate device includes a receiver antenna to detect a magnetic field from the underground facility. The locate information includes magnetic field information based on the detected magnetic field, and geographic information indicating at least one location of the locate device during the locate operation. One or more characteristics of the electronic detection mark(s) is/are based on the magnetic field information, and one or more positions in the display field at which the electronic detection mark(s) is/are displayed is/are based on the geographic information.

Abstract: Docking stations and docking methods are provided for use with marking devices used for marking the presence or absence of an underground facility in a dig area. The docking station may serve as a home base for storage of a marking device, for charging the battery of a marking device, for transferring data to and from a marking device, and for securing a marking device against unauthorized use and/or theft. The docking station may be a mobile docking station that is installed in a vehicle or may be a fixed docking station that is installed at a central location in the field, at a central office, at a home base facility, and the like.

Abstract: Methods and apparatus for providing on a display device an electronic rendering of a marking operation to mark on ground, pavement, or other surface a presence or an absence of at least one underground facility. One or more electronic locate marks are displayed in a display field of the display device, based at least in part on one or more actuation data sets representing at least one physical locate mark created by an actuation of a marking device used for the marking operation. Exemplary actuation data sets comprise at least two pieces of geographic information for a corresponding physical locate mark. Electronic locate marks may be rendered statically or dynamically in the display field (e.g., as feedback during the marking operation, and/or in a timed sequence so as to recreate the marking operation), and may be overlaid on a digital image of work site/dig area in which the marking operation is performed.
