ABSTRACT:
A system and method for determining a distance of a utility asset from a moving equipment. The invention determines a first current location of the equipment; accesses stored coordinates for a plurality of utility assets; selects an area of interest including a portion of the plurality of utility assets; identifies local utility assets in the selected area; determines a utility asset nearest to the first current position of the equipment, from the local utility assets; determines velocity and direction of the moving equipment; and determines the distance from the nearest utility asset to the second current location of the equipment responsive to the determined velocity and direction of the equipment. The invention may then generate a warning indication responsive to the determined distance.
