Abstract
A digital image (e.g., a facility map, an aerial/satellite image, an engineering drawing) is displayed on a display device of a locate receiver used to detect a presence or absence of an underground facility. Image data used to generate the image is selected based on information obtained from a ticket associated with a locate operation for which the locate receiver is used, and geographic information indicative of a location of the locate receiver. Based on a strength of a magnetic field received by an RF antenna of the locate receiver, one or more electronic markings representing a detected presence of the underground facility are overlaid on the displayed digital image.
