ABSTRACT:
A map information server is disposed on the Internet, and when a position on a page is input, the map information server searches latitude information and longitude information corresponding to the position, encodes the latitude information and longitude information to a character string corresponding to a predetermined rule, and displays the resultant character string. When an encoded character string of latitude information and longitude information is input, the map information server searches the position corresponding to the latitude information and longitude information and displays the position on a map. In addition, when latitude information and longitude information are input, the map information server encodes the latitude information and longitude information to a code of a character string corresponding to a predetermined rule. When an encoded character string of latitude information and longitude information is input, the map information server decodes the character string to latitude information and longitude information. As position information, since an encoded character string of latitude information and longitude information is used, the number of codes is decreased. Thus, the position information can be easily sent.
