A locate receiver to detect an underground facility includes an RF antenna to receive a magnetic field and provide an output signal based on the received magnetic field, and a processing circuit for determining a magnetic field strength of the magnetic field based on the output signal. The locate receiver also includes a display device, a memory and a processor. A map image based on facilities map data is displayed on the display device. The processor compares a first location at which an indication of detection of the underground facility is generated to a second location of a facility line as indicated by the first map data, and generates an alert based on a disagreement between the first location and the second location.
