Abstract
A mobile detection device for an evaluation of a location information of one or more occluded utility lines. The device comprises at least two magnetic detector units with detection coils for an alternating magnetic field. An electronic signal evaluation unit derives the location information of the utility line according to a difference in the electrical signals from the detector units. A spectral analyzing unit derives a spectral signature of a detected signal and a data link is established to a server, at which an identification of a type or class of one or more utility lines is derived by comparing the spectral signature to a database of signatures of known utility lines. A resulting utility line identification information is provided to the detection device. A visualisation unit of the device charting the one or more utility lines with the utility line location information and providing the utility line identification information.
