Position determining method for use in navigation device of e.g. mobile radio telephone, involves storing digitalized image of map in storage, and determining calibration additional information that enables image calibration in coordinates

摘要

The method involves storing a digitalized image of a map in a data storage, and selecting a point of the image of the map. Location coordinates of a location, which corresponds to the selected point of the image, are determined and assigned to the selected point of the image. Calibration additional information that enables a calibration of the image of the map in the location coordinates is determined.
