摘要： There is disclosed an apparatus for displaying a current location of a running body in which a constantly changing location of the running body on a two-dimensional coordinates is successively computed, while detecting a running distance of the running body and a running direction of the same, and the current location of said running body is displayed renewally, in accordance with the data thus computed, on a display screen having a map previously displayed thereon. The apparatus comprises means for extracting a linear running portion from current location of the running body obtained by storing data of the current location, means for extracting a linear road portion from adjoining roads on the map which corresponds to the linear running portion extracted from the current location means for effecting matching between the extracted linear running portion and linear road portion, depending on their positional relationship and means for putting the current location, onto the road to which the matching has been effected.
