Abstract:
1. A method for determining a distance of a utility asset from a moving equipment, the method comprising: electronically determining a first current location of the equipment; electronically accessing stored coordinates for a plurality of utility assets; selecting an area of interest including a portion of the plurality of utility assets; identifying local utility assets in the selected area; electronically determining a utility asset nearest to the first current location of the equipment, from the local utility assets; determining velocity and direction of the moving equipment; and electronically determining the distance from the nearest utility asset to a second current location of the equipment responsive to the determined velocity and direction of the equipment, wherein—the distance from the nearest utility asset to the second current location of the equipment (NTR) is corrected by NTR where Δt is the processing time t and V is the velocity of the equipment.
