A method of displaying a map by displaying a map on a user terminal or the like is widely used. In this case, the user needs to associate a map on the terminal with a real-world landscape. The association here means the association between the landmark on the map and the landmark in the real world. For example, it is necessary to confirm which building in the real world is the building described on the map. If an incorrect association is made, the current location on the map may be misidentified or the direction may be different from the presented guidance direction. In addition, it is necessary to change the mark on the map in accordance with changes in the real world (for example, when a convenience store is newly created instead of a bookstore). The correction cost associated with this change work is large and requires labor.

  On the other hand, a system using an electronic tag for route guidance is known. The electronic tag is installed near the object to be a landmark on the route, and the user can be guided to the destination by sequentially displaying the electronic tag of the object located on the route to the destination on the terminal. .
