Abstract
More accurate location of a buried utility conveyance (10) is obtained by first detecting, via a detector (34) the actual pattern of radiation (26, 28) of a locating signal impressed on the conveyance. The actual pattern of radiation is compared, by a processor (36) to each of a plurality of reference patterns stored in a database (38), each pattern representing the radiation for a conveyance having a known location. The processor selects the reference pattern that most closely the actual pattern and then provides an indication of the conveyance location associated with the selected reference pattern.
