A boring tool is moved through the ground within a region along a path from a starting point. A reference path is established. An information generating arrangement is located partially at the boring tool and partially at the locator including a transmitter for transmitting an electromagnetic signal from the boring tool and a receiver in the portable locator to generate certain information about the position of the boring tool relative to the position of the locator. The boring tool is moved in cooperation with the locator to establish a series of boring tool locations on the particular path such that each boring tool location is associated with one of a series of associated reference points on the reference path. An actual path of the boring tool is established which actual path corresponds to a particular path taken by the boring tool and a record is saved.
