Information updating device, its method, its program and storing medium storing the program

Abstract

A processor () of a map information generating device () acquires annotation data for displaying a location adjusting annotation about, for instance, a feature that is newly built and set a locatable position of a location-adjusting-annotation character string of the location adjusting annotation at a position substantially corresponding to a position where the feature of the location-adjusting-annotation character string exists but not overlapping with an existing annotation. Then, the processor () updates the annotation data based on the location state of the location-adjusting-annotation character string and stores it in the storage section (). When determining that that all annotations cannot be located so as not to overlap with each other only by adjusting the locatable position of the location-adjusting-annotation character string, the processor () sets the location-adjusting-annotation character string at a predetermined position, while performing location adjusting processing of an overlapped-existing-annotation character string that overlaps with the location-adjusting-annotation character string to be located at the predetermined position.
