Abstract
Methods and apparatus for facilitating detection of a presence or an absence of at least one underground facility within a dig area. A digital image of a geographic area including the dig area is electronically received, and at least a portion of the received digital image is displayed on a display device. The dig area is delimited on the displayed digital image, via a user input device associated with the display device, so as to generate a marked-up digital image including a delimited dig area, without acquiring geographic coordinates to delimit the dig area. Information relating to the dig area is electronically transmitted and/or electronically stored so as to facilitate the detection of the presence or the absence of the at least one underground facility within the dig area.
