Abstract: A method and apparatus, including software, for the development and operational use of precise utility location and utility asset management information. Field-usable data sets may be produced that meet standards of accuracy and usability that are sufficient for use by field operations personnel participating in damage prevention activities associated with ground penetrating projects (e.g., excavating, trenching, boring, driving, and tunneling) or other asset applications. Some embodiments relate to integrating utility asset data including coordinate location, and geographical information data using a consistently available and accurate coordinates reference for collecting the data and for aligning the geographical information data. Some embodiments relate to managing projects with equipment that provides real time images and the updating of the data as required with this desired accuracy.

Abstract: A method of dynamically tracking a location of one or more selected utilities. A first step involves providing a portable controller having a memory. A global positioning system (GPS) co-ordinate device and a display are coupled to the controller. A second step involves storing in the memory of the controller a series of GPS co-ordinates for the one or more selected utilities within an assigned service area of a municipality. A third step involves using the GPS co-ordinate device to dynamically provide GPS co-ordinates to the controller as positioning of the GPS co-ordinate device changes. A fourth step involves using the display to display the GPS co-ordinates of the GPS co-ordinate device on a scrolling display of GPS co-ordinates, together with the series of GPS co-ordinates for the one or more selected utilities, such that the relative position of the GPS co-ordinate device to the one or more selected utilities is always known.
