1. A locate receiver to detect a presence or an absence of an underground facility, the locate receiver comprising:

  • a housing;

    an RF antenna for receiving a magnetic field and outputting an output signal;

    a processing circuit, for receiving the output signal from the RF antenna and determining a magnetic field strength of the magnetic field;

    a display device coupled to the housing;

    at least one memory; and

    at least one processor, coupled to the processing circuit, the display device and the at least one memory, configured to;

    display on the display device a map image that is generated based on first map data that comprises facilities map data and is selected by the at least one processor; and

    compare, by the at least one processor, 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 generate an alert based on a disagreement between the first location and the second location.
