1. An apparatus for facilitating generation of an electronic manifest of at least one physical locate mark applied to a ground surface by a technician at an excavation site prior to excavation activities, the apparatus comprising:

  • a communication interface;

    a display device;

    a memory to store processor-executable instructions; and

    a processing unit coupled to the communication interface, the display device, and the memory, wherein upon execution of the processor-executable instructions by the processing unit, the processing unit;

    controls the display device so as to display at least one grid to provide a reference for a geographic area including the excavation site;

    acquires user input from a user input device, the user input relating to a geographic location of the at least one physical locate mark applied by the technician to the ground surface at the excavation site to indicate a presence or an absence of at least one underground facility at the excavation site;

    further controls the display device to add to the displayed at least one grid, based at least in part on the user input acquired from the user input device, at least one digital representation of the at least one physical locate mark so as to generate a marked-up image including the at least one grid and the at least one digital representation of the at least one physical locate mark; and

    controls the communication interface and/or the memory to electronically transmit and/or electronically store information relating to the marked-up image so as to generate the electronic manifest.
