Patent number: 9958287Abstract: Based on map information acquired from a map DB, a viewpoint for viewing a ground surface on a map of a set region at a time of displaying the map is set. Altitude information that indicates an altitude of a landform present in at least a partial region of the set region is stored. In a case where the altitude information is present in the map DB at a position on the map, which is set in response to a position indicated by inputted position information, a sight direction of the viewpoint is changed, and the viewpoint is thereby set at a position higher than the altitude of the landform, which is indicated by altitude information of the position on the map. A display data for displaying, on a display device, a map in a case of viewing the ground surface from the viewpoint set is generated.Type: GrantFiled: July 18, 2014Date of Patent: May 1, 2018Assignee: MITSUBISHI ELECTRIC CORPORATIONInventor: Masafumi Asai
