Abstract
A method is provided for reporting location of a buried object detected by a utility locator device. The method includes: determining location of a buried object using electromagnetic field emissions emitted from a utility locator device, determining global coordinates for the location of the buried object using a global positioning system (GPS), determining an accuracy measure for the global coordinates using the accuracy of the location determined by the locator and the accuracy of the GPS; and reporting the global coordinates for the buried object, along with the accuracy measure, to an operator of the utility locator device. An operator of the locator may be notified when the accuracy measure for the global coordinates exceeds a tolerance for reporting the location of the buried object.
