Spot-specifying code providing method using communication between server and client terminal

摘要

A client terminal can obtain a spot-specifying code by accessing a server via the Internet. At first, when a user wants to obtain a spot-specifying code pertinent to a spot, the user appoints the spot on a map shown in a display of the client terminal. When the user appoints the several spots on the map, marks and numerals that indicate the appointed spots are displayed. Upon finishing appointment of all the spots, the user clicks a button of "ISUUE SPOT-SPECIFYING CODE.' The server then converts coordinates of the appointed spots into the spot-specifying codes using a conversion table to make a file. The file is thereby downloaded to the terminal.
