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.
