Information processing system, information processing method, and information processing program

An information processing method, comprising:

• by an information processing system including,
• a first information processing terminal that includes a first display apparatus and is configured to display on the first display apparatus a first map and a first route from a current location to a destination in a superimposed manner, the first map being created using a first creation system, and
• a second information processing terminal that is capable of communicating with the first information processing terminal, includes a second display apparatus, and is configured to display on the second display apparatus a second map and a second route from the current location to the destination in a superimposed manner, the second map being created by a second creation system,
• displaying an integrated map, synchronized between the first display apparatus and the second display apparatus, the integrated map being a map obtained by integrating the first map and the second map;
• and
• displaying an integrated route, synchronized between the first display apparatus and the second display apparatus, the integrated route being a route obtained by integrating the first route and the second route.

An information processing program that causes

• a processor of
• a first information processing terminal that includes a first display apparatus and is configured to display on the first display apparatus a first map and a first route from a current location to a destination in a superimposed manner, the first map being created using a first creation system, or
• a second information processing terminal that is capable of communicating with the first information processing terminal, includes a second display apparatus, and is configured to display on the second display apparatus a second map and a second route from the current location to the destination in a superimposed manner, the second map being created by a second creation system, to operate to:
• display an integrated map, synchronized between the first display apparatus and the second display apparatus, the integrated map being a map obtained by integrating the first map and the second map;
• and
• display an integrated route, synchronized between the first display apparatus and the second display apparatus, the integrated route being a route obtained by integrating the first route and the second route.
