A method and device for displaying map data and related data and thereby permitting easy enlargement of the scope of the application of map-based data services, wherein additional drawing data for superposing on a map displayed on a screen, and setting data for specifying a map display, are sent and received between different application programs using inter-application exchange in a standard data format. Required map data and related data are displayed on the screen using a first application program having a function for converting received additional drawing data and setting data to the aforesaid data format and transmitting it by inter-application exchange, then using a second application program which displays a map on the display screen according to the setting data transmitted by the first application program and displays additional data on the screen map corresponding to the additional drawing data.

[ What is claimed is:] [1.]1. A data structure system for providing map data and data related to said map data at a user terminal, comprising:map data means for regularly updating and storing said map data corresponding to position data, for sending a map data search page to said user terminal, for retrieving said regularly updated map data according to multiple searching parameters simultaneously entered by a user using said map data search page, said multiple searching parameters including information in addition to a location name, and for displaying at said user terminal only said regularly updated map data retrieved according to said searching parameters when said user directly accesses said regularly updated map data;position data means for storing said position data and first map-related data in accordance with one of said position data and said map data, for sending a position data and first map-related data search page to said user terminal, for retrieving said position data and said first map-related data according to said multiple searching parameters entered by said user using said position data and first map-related data search page, and for displaying at said user terminal only said position data and said first map-related data retrieved according to said multiple searching parameters when said user directly accesses said position data and said first map-related data;guide data means for storing second map-related data, for sending a guide data search page to said user terminal, for retrieving said second map-related data according to said searching parameters entered by said user using said guide data search page, and for displaying at said user terminal only said second map-related data retrieved according to said multiple searching parameters when said user directly accesses said second map-related data, wherein said guide data means selectively displays map data corresponding to said second map-related data and said second map-related data only when said user presses a map button displayed with said second map-related data at said user terminal; andnetwork means for transferring to said map data means, to said position data means, and to said guide data means said searching parameters entered using said map data search page, said searching parameters entered on said position data and first map-related data search page and said searching parameters entered on said guide data search page, respectively, and for transferring from said map data means said regularly updated map data, from said position data means said position data and said first map-related data, and from said guide data means said second map-related data and said map data, whereinsaid map data means, said position data means, and said guide data means are linked together.
