Abstract

A system for wirelessly tracking utility assets comprises a remote wireless modem, a remote asset tracking computer in communication with the remote wireless modem, and a wireless utility asset mapping device in wireless long distance communication with the remote wireless modem. A utility asset is located, the wireless utility asset mapping device is placed over the location of the utility asset, and a coordinate is determined. The coordinate is wirelessly transmitted over long distance in both low density and high density areas. The coordinate is received and then transmitted to a remote asset tracking computer. The coordinate is stored in a database in the remote asset tracking computer. The remote asset tracking computer may also comprise a geographic information system in communication with the database.

Claims

1. A method for wirelessly mapping utility assets comprising:

locating an unmapped or inaccurately mapped utility asset, wherein the utility asset has unknown or unverified geographical coordinates;

placing a wireless utility asset mapping device over the location of the utility asset;

determining a geographical coordinate of the wireless utility asset mapping device;

wirelessly transmitting the coordinate reliably in low density and high density areas;

wirelessly receiving the coordinate;

transmitting the received coordinate to a remote asset tracking computer; and

storing the coordinate in a database in the remote asset tracking computer.

2. The method claim 1 wherein said wirelessly transmitting comprises wirelessly transmitting over at least 500 feet in low density and high density areas.
