Abstract
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 a two-dimensional coordinates is successively computed and the current location of said running body is displayed successively, in accordance with the data thus computed, on a display screen having a map previously displayed thereon. According to this apparatus, longitude and latitude values of a reference point in a mesh consisting of lines of longitude and latitude in each map of divided areas are registered as known factors and the current location of the running body on the two-dimensional coordinates thus computed is converted to a location on longitude-latitude coordinates, whereby the current location on the map is calculated from the known longitude and latitude values of the reference point displayed on the display screen.
