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.
