SYSTEMS, METHODS AND APPARATUS RELATING TO GENERATION, TRANSMISSION, ACCESS AND STORAGE OF VIRTUAL WHITE LINE (VWL) IMAGES AND DATA FOR EXCAVATION PROJECTS

摘要

Systems, 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. 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 of a staged excavation project, the input image, or a plurality of associated images, may be marked-up to include multiple dig area indicators corresponding to multiple stages of the staged excavation project.
