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