A method for determining a spatially resolved extent of error for position finding with a global navigation satellite system for a target area of interest using field data from a plurality of field apparatuses, particularly motor vehicles (2), that each have a receiver (3) for the global navigation satellite system and are at least intermittently situated in the target area, comprising the following steps: –ascertainment of at least one field data record (5), comprising a current GNSS position (7) in the target area and an error value (8) associated with said position, by the field apparatuses, – transmission of the field data records (5) to a central computation device (12), – ascertainment and update of an error map (14), containing the extents of error for various positions and/or subareas in the target area, by virtue of statistical evaluation of the field data records (5) in the central computation device (12). |
