Abstract: One or more pieces of equipment (e.g., a locate wand, a marking tool) are used to perform an operation to identify, in response to a ticket, a presence or an absence of an underground facility at a dig area. Data relating to the use of the equipment to perform the operation is electronically processed to determine whether the operation was completed correctly. In one example, ticket information from the ticket also is processed with the data relating to the use of the equipment to determine whether the operation was completed correctly. In another example, the equipment includes a marking apparatus, and data relating to the use of the marking apparatus that is processed includes one or more of marker characteristic information, timing information, supply information and location information relating to one or more markers dispensed by the marking apparatus.

Abstract: Providing access at a jobsite to an electronic record of a locate operation. Data related to the locate operation is acquired by locate equipment and transmitted to a data repository for storage in the electronic record of the locate operation. A site-specific access mechanism is provided that establishes a link to the electronic record of the locate operation. In one example, the site-specific access mechanism is a physical mechanism, such as a printout of a website address, a barcode, or an RFID tag. In another example the site-specific access mechanism is a virtual mechanism, such as geographic location information provided by a location tracking system (e.g., GPS apparatus) and/or derived from information available to a wireless communications system or WiFi network. In one aspect, the access mechanism may be configured for use at the jobsite only by a person particularly authorized to access the electronic record of the locate operation.

Abstract: Generating an accuracy-referenced electronic record of a locate and/or marking operation performed by a locate technician. The locate and/or marking operation comprises locating and/or 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 location of the at least one underground facility and/or the at least one physical locate mark is electronically rendered on a display device so as to generate an electronic visual representation of the locate and/or marking operation. An accuracy of the represented location is digitally represented on the display device using at least one accuracy indicator overlaid on the electronic visual representation of the locate and/or marking operation so as to generate an accuracy-annotated representation of the locate and/or marking operation.

Abstract: A bare grid is displayed on a display device. At least one digital representation of at least one physical locate mark is added to the displayed grid to generate a marked-up grid. The physical locate mark(s) include(s) non-white paint and/or a non-white flag, and is/are applied during a locate operation performed after generation of and pursuant to a locate request ticket relating to a dig area that is planned to be excavated or disturbed during prospective excavation activities. The locate operation comprises providing at least one visible warning to an excavator performing the prospective excavation activities, using the physical locate mark(s), of a presence or an affirmative absence of at least one underground facility at the dig area specified in the locate request ticket. Information relating to the marked-up grid is electronically stored and/or transmitted so as to generate a searchable electronic record of the locate operation.

Abstract: Manual, semi-automated or automated image-based electronic manifests of locate operations. Image layers may be selectively enabled or disabled for display to facilitate viewing of base images and/or categories of information overlaid on the base image(s) relating to the locate operation.
