METHODS AND APPARATUS FOR GENERATING ALERTS ON A LOCATE DEVICE, BASED ON COMPARING ELECTRONIC LOCATE INFORMATION TO FACILITIES MAP INFORMATION AND/OR OTHER IMAGE INFORMATION
First Claim
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 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.

Abstract
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.
