A walk-in globe for permitting unobstructed viewing of a map of the world which includes a hollow sphere having a diameter substantially greater than that of the height of an adult person. The door provided in the sphere permits access for persons to enter the interior of the sphere. An accurately scaled map of the entire world covers the inner surface of the hollow sphere. In order to support the person within the globe, an elevated support platform is carried therein which supports a person at a height so that the eye level of the person standing on the support platform is substantially at the same level as the center of the sphere. Tracking mechanisms are provided for automatically giving the longitudinal and latitudinal coordinates of a particular location, and for automatically calculating the distances between the various locations shown on the map.
