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 NTRcorrection, where
NTRCorrection=|(Δ
t*V)·
(NTR)|/|(NTR)|
(2)where Δ
t is the processing time t and V is the velocity of the equipment.

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.

2. A system for determining a distance of a utility asset from a moving equipment comprising:
-
a global position system receiver for determining a first current location and a second current location of the equipment; a database for storing coordinates for a plurality of utility assets; means for selecting an area of interest including a portion of the plurality of utility assets; a processor for identifying local utility assets in the selected area, 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, determining 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, and adjusting the determined distance by a correction factor as a function of processing time and the determined velocity. - View Dependent Claims (3, 4, 5)
