Claim 17:
18. An information processing method comprising:
a photograph reception step of receiving a captured map photograph from a terminal device;
a determination step of searching a navigation information group that contains two or more pieces of navigation information that contain map representation data and two or more pieces of correspondence information that are each a set of coordinate information and position information on the map representation data that is one of an illustration map, a handwritten map, and a sketch map, and determining a piece of navigation information that has a relationship that satisfies a first condition, with the map photograph;
a string acquisition step of acquiring one or more strings from the map photograph; and
a navigation information transmission step of transmitting the piece of navigation information determined in the determination step, to the terminal device, wherein:
the determination step includes determining the piece of navigation information that satisfies the first condition, using the one or more strings,
region specification information that specifies a region that is covered by the piece of map representation data is stored in association with the piece of navigation information,
the string acquisition step includes acquiring three or more strings from the map photograph,
the information processing method further comprises:
a position information acquisition step of acquiring pieces of position information corresponding to pieces of location information that are three or more strings acquired in the string acquisition step, using a location dictionary that contains one or more pieces of location position information that associate the pieces of location information that specify locations and pieces of position information that specify positions of the locations with each other; and
a region specification information acquisition step of acquiring region specification information that specifies a region that is covered by the map photograph, using the three or more pieces of position information acquired in the position information acquisition step, and

the determination step includes determining a piece of navigation information corresponding to the region specification information acquired in the region specification information acquisition step and the region specification information that satisfies the first condition.
