Abstract
The present invention provides a map providing apparatus (10) that receives, from a portable terminal (30) including at least a display unit (32), a piece of position information that indicates a location point of the portable terminal (30) and transmits, to the portable terminal (30), a map image that corresponds to the received piece of position information. The map providing apparatus (10) includes: a reference direction specifying unit (104) that specifies a reference direction that is required when a user of the portable terminal (30) brings the map image displayed on the display unit (32) of the portable terminal (30) into correspondence with actual directions, based on the piece of position information received from the portable terminal (30); a reference direction information generating unit (100) that generates a piece of reference direction information for having the user of the portable terminal (30) understand the reference direction specified by the reference direction specifying unit (104); and a transmitting unit (100) that transmits, to the portable terminal, the piece of reference direction information generated by the reference direction information generating unit (100), together with the map image.

16. A map providing apparatus that receives, from a portable terminal including at least a display unit, location information indicative of a location of a portable terminal held by a user, and transmits a map image that corresponds to received location information to the portable terminal, the map providing apparatus comprising:
-
a reference direction specifying unit that, based on the received location information, specifies a reference direction that is a direction required when a user of the portable terminal brings the map image displayed on the display unit of the portable terminal into correspondence with actual directions and that is a direction of a target object that can be visually recognized by the user from the location;
a reference direction information generating unit that generates reference direction information for having the user understand specified reference direction; and
a transmitting unit that transmits generated reference direction information together with the map image to the portable terminal. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
