A technique is described for correcting digitized map data stored in a map database of a navigation device, wherein the map data comprises routing data in the form of route links and shape points, and wherein each route link is associated with a sequence of shape points representing a course of a road segment that is displayable on a navigation screen. A method aspect comprises the steps of detecting a first user input operation indicative of a selection of a road segment displayed on the screen, detecting at least one second user input operation indicative of a graphical manipulation of the course of the selected road segment on the screen, generating on basis of the detected second user input operation corrected routing data reflecting the manipulated course of the selected road segments and storing the corrected routing data in the map database. |
