Control of locating equipment used by a locate technician to perform a locate and/or marking operation to detect and/or mark a presence or an absence of at least one underground facility at a work site is based at least in part on marking specifications (e.g., government-based regulations, industry-based recommended guidelines/best practices, standard operating procedures of locate companies and/or facility owners, and/or contractual obligations relating to marking operations). In various examples, control signals are generated to alert a locate technician when to start and stop dispensing of a marking material, or control signals are generated to automatically or semi-automatically control dispensing of the marking material by a marking device, so as to facilitate compliance with marking specifications.
Indicating a precise geographic extent and a precise geographic location of a dig area at a work site at which excavation is planned, to facilitate detection and/or marking of a presence or an absence of an underground facility in the dig area. A graphical user interface includes an aerial image of a geographic area proximate to and including the work site and the dig area, and a drawing tool to facilitate placement of one or more dig area indicators on the aerial image. A user uses the drawing tool to delimit the precise geographic extent and the precise geographic location of the dig area(s) on the displayed aerial image so as to form the dig area indicator(s), representing unbuffered dig areas, and thereby generate a marked-up aerial image. Geographic coordinates are determined corresponding to the unbuffered dig area(s) represented by the dig area indicator(s). A locate request ticket is generated that includes the marked-up aerial image itself, the geographic coordinates corresponding to the unbuffered dig area(s), and/or a link to a webpage at which the marked-up aerial image may be viewed and/or the geographic coordinates may be accessed.
Control of locating equipment used by a locate technician to perform a locate and/or marking operation to detect and/or mark a presence or an absence of at least one underground facility at a work site (e.g., locate receivers, locate transmitters, marking devices and/or combined locate and marking devices) is based on time-keeping information associated with the technician and/or wage and hour compliance information.
