Methods and apparatus for generating a searchable electronic record of a locate operation in which a locate technician, using one or more physical locate marks, identifies a presence or an absence of at least one underground facility within a dig area. A digital image of a geographic area comprising the dig area is electronically received, and at least a portion of the received digital image is displayed on a display device. Location information regarding an identified location of the at least one physical locate mark is also electronically received and, based at least in part on the received location information, one or more digital representations of the identified location of the physical locate mark(s) is/are included in the displayed digital image so as to generate a marked-up digital image. Information relating to the marked-up digital image is electronically stored and/or electronically transmitted so as to generate the searchable electronic record of the locate operation.
