The disclosure relates to a locating system, comprising at least one hand-held locating sensor, which is provided for capturing locating data related to objects to be located that are hidden under an examination surface, a position sensor, which is provided for capturing position data, which can be associated with the locating data, and an evaluating unit, which is provided for determining at least two-dimensional map information from the locating data and the position data and providing said at least two-dimensional map information. According to the disclosure, the locating system comprises at least one data source, which is provided for providing data for the purpose of a modification of the at least two-dimensional map information.

A hand-held locating apparatus comprises at least one hand-held locating device for acquiring locating data on objects that are hidden below a surveyed surface and are to be located, and comprises a position sensor for sensing position data of the locating device in relation to the surveyed surface. The locating system includes at least one evaluation device for determining directionally and/or spatially resolved location information from the locating data in a first mode of operation of the locating system without repositioning the locating device in relation to the surveyed surface and for determining at least three-dimensional locating information from the locating data and the position data by assigning locating data to position data in a second mode of operation. Also disclosed is a method for locating objects hidden below a surveyed surface, wherein the at least two modes of operation of the locating system can be selected.

The disclosure relates to a method for operating an imaging location device by which at least two-dimensional map information is generated by location of concealed location objects under an examination surface. It is proposed that a handling instruction for guiding the location device is derived using an evaluation unit of the location device from positioning data determined by means of a location unit of the location device and/or from position data determined by means of a position sensor of the location device and/or from system parameters of the location device, in order to obtain optimized accrual of map information relating to the location.

An imaging locating device includes a first locating apparatus, a position sensor, and an evaluation apparatus. The first locating apparatus is configured to detect locating data in relation to objects to be located. The objects are concealed under an examination surface. The position sensor is configured to detect position data of the locating device in relation to the examination surface. The evaluation apparatus is configured to determine a first at least two-dimensional map information items by assigning the locating data of a first category from the first locating apparatus to the position data. The evaluation data is further configured to determine at least one further at least two-dimensional map information item. The at least one further at least two-dimensional map information item differs from the first at least two-dimensional map information item.
