There is disclosed an apparatus for displaying a travel path of a running body in which a constantly changing location of the running body on two-dimensional coordinates is successively computed and the current location of the running body is displayed successively, in accordance with the data thus computed, on a display screen having a map previously displayed thereon, comprising: means for registering as known factors longitude and latitude values of reference points, each of which is formed by an intersection point of a mesh consisting of lines of longitude and latitude on the map, the map having divided areas; means for converting the current location of the running body on the two-dimensional coordinates to a position on latitude-longitude coordinates; means for calculating the current location on the map, on the basis of the known latitude-longitude values of a reference point on the map displayed on the display screen; means for displaying the current locations on the display screen, wherein the latitude-longitude of a position of a target point set on a map displayed on the display screen is calculated from the reference point of the map and means is provided to obtain and display a distance between the current location of the running body and the target point from a difference in position between latitude-longitude coordinates of the current location of the running body displayed on the map of one area and of the target point displayed on the map of another area. |
